For organizations running complex OLTP systems, the friction point is rarely standard SQL; it is the deep integration of Oracle-specific PL\/SQL logic.<\/p>\n<p>When evaluating a replacement, the distinction between &quot;standard SQL support&quot; and &quot;Oracle PL\/SQL engine replication&quot; is the primary determinant of migration success. Many open-source options support standard SQL queries but lack the semantic depth required to execute legacy stored procedures, packages, and triggers without significant refactoring.<\/p>\n<p>KingbaseES, as a commercial database product, positions itself within the commercial alternative space by targeting this specific compatibility gap. Rather than offering a generic SQL engine, it provides support for the proprietary syntax that defines legacy Oracle applications.<\/p>\n<h3>Deep PL\/SQL Syntax Support<\/h3>\n<p>The migration risk for enterprise OLTP workloads is highest when moving code that relies on procedural extensions. KingbaseES supports a broad spectrum of commonly used Oracle PL\/SQL syntax elements, which directly addresses the complexity of legacy application logic. Supported constructs include:<\/p>\n<ul>\n<li>Control Flow: Assignment statements, <code>IF-THEN-ELSE<\/code>, <code>CASE<\/code> statements, and <code>GOTO<\/code> statements.<\/li>\n<li>Looping Structures: <code>LOOP<\/code>, <code>WHILE-LOOP<\/code>, and <code>FOR LOOP<\/code> statements.<\/li>\n<li>Cursor Management: <code>REF CURSOR<\/code> cursors, <code>RETURNING INTO<\/code> statements, and <code>EXECUTE IMMEDIATE<\/code>.<\/li>\n<li>Collection Handling: Support for <code>BULK COLLECT<\/code> and PL\/SQL collection types.<\/li>\n<li>Autonomous Transactions: Full support for transaction processing in PL\/SQL, including autonomous transactions.<\/li>\n<\/ul>\n<p>This level of syntactic alignment suggests that applications heavily reliant on procedural logic can potentially migrate with less code rewriting than would be required for databases that only support standard SQL.<\/p>\n<h3>Complex Data Types and Pseudo-Columns<\/h3>\n<p>Beyond syntax, the data model itself presents a barrier. Oracle applications often utilize complex data types that are not part of the ANSI SQL standard. KingbaseES supports these specific types, reducing the need for schema redesign:<\/p>\n<ul>\n<li>Record and Type Attributes: Support for <code>RECORD<\/code> types, <code>%TYPE<\/code> attributes, and <code>%ROWTYPE<\/code> attributes.<\/li>\n<li>Advanced Collections: Compatibility with associative arrays, variable arrays, and nested tables.<\/li>\n<li>Pseudo-Columns: Direct support for Oracle pseudo-columns such as <code>CURRVAL<\/code>, <code>NEXTVAL<\/code>, and <code>LEVEL<\/code>.<\/li>\n<\/ul>\n<p>By maintaining compatibility with these proprietary features, KingbaseES reduces the &quot;refactoring tax&quot; that often plagues migrations to generic SQL databases. However, while &quot;most commonly used SQL statements&quot; are supported, this does not equate to a 100% feature parity guarantee for every proprietary Oracle extension. The suitability of KingbaseES depends on the specific subset of Oracle features utilized by the enterprise&#8217;s current workload.<\/p>\n<h2>Commercial vs. Open-Source: The Licensing and Support Trade-off<\/h2>\n<p>A common narrative in the search for an alternative to Oracle database is the assumption that the only viable path to cost reduction is moving to open-source software. This binary view often overlooks the operational realities of enterprise OLTP systems, where vendor support, warranty, and defined service level agreements (SLAs) are non-negotiable.<\/p>\n<p>KingbaseES is strictly a commercial database product. It is not open-source, nor is it source-available or community-supported. This distinction is fundamental for procurement teams and architects evaluating risk and cost structures.<\/p>\n<h3>The Commercial Value Proposition<\/h3>\n<p>Unlike open-source alternatives like PostgreSQL or MySQL, which rely on community forums or third-party support contracts, KingbaseES operates under a defined commercial licensing model. The product includes a software license certificate that explicitly defines:<\/p>\n<ul>\n<li>Product name and version type.<\/li>\n<li>Service period.<\/li>\n<li>Serial number.<\/li>\n<li>Restrictions on rights, including prohibitions on reverse engineering, decompilation, and transfer.<\/li>\n<li>Limited warranty and limited liability terms.<\/li>\n<\/ul>\n<p>This commercial framework provides a clear legal and operational boundary for enterprises that cannot risk the ambiguity of community-supported software for mission-critical data.<\/p>\n<h3>Comparison of Licensing and Support Models<\/h3>\n<table>\n<thead>\n<tr>\n<th style=\"text-align:left\">Feature<\/th>\n<th style=\"text-align:left\">KingbaseES (Commercial)<\/th>\n<th style=\"text-align:left\">PostgreSQL \/ MySQL (Open Source)<\/th>\n<th style=\"text-align:left\">Oracle Database (Incumbent)<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td style=\"text-align:left\"><strong>Licensing Model<\/strong><\/td>\n<td style=\"text-align:left\">Commercial license with defined terms, service period, and restrictions.<\/td>\n<td style=\"text-align:left\">Free to use, but enterprise support requires third-party or Red Hat\/SUSE contracts.<\/td>\n<td style=\"text-align:left\">Commercial, typically processor-based or named-user licensing.<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align:left\"><strong>Support Source<\/strong><\/td>\n<td style=\"text-align:left\">Direct vendor support with defined SLAs and warranty.<\/td>\n<td style=\"text-align:left\">Community forums or paid third-party support vendors.<\/td>\n<td style=\"text-align:left\">Direct vendor support with enterprise SLAs.<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align:left\"><strong>Warranty<\/strong><\/td>\n<td style=\"text-align:left\">Limited warranty and liability as per license certificate.<\/td>\n<td style=\"text-align:left\">Generally no warranty; &quot;as-is&quot; basis unless purchased via third party.<\/td>\n<td style=\"text-align:left\">Comprehensive warranty and liability coverage.<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align:left\"><strong>Reverse Engineering<\/strong><\/td>\n<td style=\"text-align:left\">Restricted by license agreement.<\/td>\n<td style=\"text-align:left\">Generally permitted (source available).<\/td>\n<td style=\"text-align:left\">Restricted by license agreement.<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align:left\"><strong>Target Use Case<\/strong><\/td>\n<td style=\"text-align:left\">Enterprises requiring commercial support with Oracle-like compatibility.<\/td>\n<td style=\"text-align:left\">Greenfield projects, cost-sensitive deployments, or organizations with strong in-house DBA teams.<\/td>\n<td style=\"text-align:left\">Mission-critical systems with established Oracle dependencies.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>For organizations evaluating migration, the decision often hinges on whether the organization can absorb the risk of self-managing complex infrastructure. KingbaseES offers a middle ground: it provides the Oracle-like compatibility required to minimize migration effort while maintaining the commercial support structure necessary for enterprise reliability.<\/p>\n<h2>Migration Architecture: From Oracle RAC to Commercial Clustering<\/h2>\n<p>High availability (HA) and disaster recovery (DR) are non-negotiable for enterprise OLTP workloads. When migrating from Oracle, the primary architectural concern is often the transition from Oracle Real Application Clusters (RAC) to an equivalent HA solution in the target database.<\/p>\n<p>KingbaseES supports high availability configurations, which is a critical requirement for maintaining business continuity. However, the architectural implementation differs from Oracle RAC, and understanding these differences is essential for capacity planning and SLA definition.<\/p>\n<h3>Architectural Considerations<\/h3>\n<p>While specific failover times and node limits for KingbaseES clustering are not detailed in the general evidence provided, the system&#8217;s support for high availability indicates a capability to handle enterprise-grade redundancy.<\/p>\n<p>When evaluating the migration architecture, organizations should consider:<\/p>\n<ol>\n<li>Clustering Model: Oracle RAC uses a shared-disk architecture (or shared-nothing with specific synchronization). Commercial alternatives like KingbaseES typically utilize shared-nothing or master-slave replication models. The shift requires a review of the application&#8217;s concurrency and locking mechanisms.<\/li>\n<li>Failover Mechanisms: The transition involves defining how the system handles node failures. Enterprises must validate that the KingbaseES HA configuration meets their Recovery Time Objective (RTO) and Recovery Point Objective (RPO).<\/li>\n<li>Operational Overhead: Moving from a unified RAC environment to a distributed HA setup may require changes in operational procedures, monitoring tools, and backup strategies.<\/li>\n<\/ol>\n<h3>Migration Steps for High Availability<\/h3>\n<p>To ensure a smooth transition to a high-availability architecture, the following steps are recommended:<\/p>\n<ol>\n<li>Assess Current RAC Topology: Document the current Oracle RAC configuration, including node count, storage architecture, and network topology.<\/li>\n<li>Define HA Requirements: Establish the required RTO and RPO for the new environment based on business criticality.<\/li>\n<li>Select HA Configuration: Choose the appropriate KingbaseES high availability mode (e.g., synchronous replication, asynchronous replication) that aligns with the defined requirements.<\/li>\n<li>Validate Failover Scenarios: Conduct controlled failover tests to measure actual recovery times and ensure data consistency.<\/li>\n<li>Update Application Logic: Ensure the application can handle connection failover, particularly if the HA implementation involves virtual IP (VIP) changes or connection pooling adjustments.<\/li>\n<li>Implement Monitoring: Deploy monitoring tools to track the health of the HA cluster and alert on potential issues before they impact availability.<\/li>\n<\/ol>\n<p>Note that while KingbaseES supports high availability, the specific architectural details (such as the exact failover time or maximum node count) must be verified against the specific version and deployment scenario. Enterprises should not assume identical behavior to Oracle RAC without validating the specific configuration against their workload.<\/p>\n<h2>The Migration Friction Point: Tooling and Refactoring Effort<\/h2>\n<p>The most significant risk in migrating an alternative to Oracle database is not the data movement itself, but the conversion of complex business logic. Oracle applications often rely on proprietary features like stored procedures, packages, and triggers that are not part of the standard SQL ecosystem.<\/p>\n<h3>Distinguishing Data Migration from Logic Migration<\/h3>\n<p>Data migration (ETL) is a well-understood process, often handled by standard tools. However, migrating the <em>logic<\/em> that sits on top of the data requires a different approach.<\/p>\n<ul>\n<li>Standard SQL: Most databases support standard SQL, making data migration relatively straightforward.<\/li>\n<li>PL\/SQL Logic: This is the friction point. If the target database does not support the specific syntax and data types used in the source Oracle database, the application code must be refactored.<\/li>\n<\/ul>\n<p>KingbaseES addresses this by supporting a wide range of Oracle PL\/SQL syntax and complex data types. This reduces the need for a complete application rewrite. However, the migration process is not entirely automated.<\/p>\n<h3>Migration Pathways and Tooling<\/h3>\n<p>Evidence indicates that migration from MySQL to KingbaseES is a documented process involving specific steps. While a direct &quot;Oracle to KingbaseES&quot; migration tool success rate is not explicitly detailed in the provided evidence, the syntactic compatibility suggests that the migration effort will be significantly lower than for databases that lack PL\/SQL support.<\/p>\n<p>The migration process generally involves:<\/p>\n<ol>\n<li>Schema Conversion: Converting Oracle data types to KingbaseES equivalents. Given the support for complex types (nested tables, associative arrays), the schema conversion may require minimal changes for many applications.<\/li>\n<li>Code Conversion: Converting PL\/SQL blocks. The support for loops, cursors, and pseudo-columns (<code>CURRVAL<\/code>, <code>NEXTVAL<\/code>) means that many stored procedures can be migrated with minimal modification.<\/li>\n<li>API Integration: Ensuring the application connects correctly using supported APIs. KingbaseES provides usage instructions for standard interfaces including JDBC, ODBC, DCI, and ESQL.<\/li>\n<li>Testing and Validation: Rigorous testing of the migrated code to ensure functional parity and performance stability.<\/li>\n<\/ol>\n<h3>Refactoring Requirements<\/h3>\n<p>Even with strong compatibility, some refactoring is often necessary. Enterprises should be prepared for:<\/p>\n<ul>\n<li>Unsupported Features: Identifying any Oracle-specific features not supported by KingbaseES (e.g., specific Pro*C features or proprietary extensions not covered by the PL\/SQL syntax support).<\/li>\n<li>Performance Tuning: Re-optimizing queries that were tuned for Oracle&#8217;s specific execution plans.<\/li>\n<li>Testing: Validating that the migrated logic produces the same results under load.<\/li>\n<\/ul>\n<p>The existence of a migration guide for MySQL to KingbaseES demonstrates a structured approach to migration, but organizations migrating from Oracle should expect to invest in a detailed analysis of their specific PL\/SQL dependencies to estimate the true effort.<\/p>\n<h2>TCO Modeling: Avoiding the &#8216;Hidden Cost&#8217; of Migration<\/h2>\n<p>Total Cost of Ownership (TCO) is the ultimate metric for evaluating an alternative to Oracle database. While licensing costs are a primary driver for migration, they represent only a portion of the total cost. The &quot;hidden costs&quot; often lie in migration labor, refactoring, and long-term operational changes.<\/p>\n<h3>Components of TCO<\/h3>\n<p>When modeling TCO for KingbaseES or other alternatives, enterprises must account for:<\/p>\n<ul>\n<li>Licensing Costs: KingbaseES is a commercial product with defined licensing terms. Unlike open-source options, it incurs a direct cost, but this cost includes vendor support and warranty. The pricing structure (e.g., per-core, per-processor, or subscription) must be obtained directly from the vendor for accurate modeling.<\/li>\n<li>Migration Labor: The cost of the engineering effort required to convert data, schema, and PL\/SQL code. High compatibility reduces this cost, but it is rarely zero.<\/li>\n<li>Refactoring Costs: The cost of rewriting code for features not supported by the target database. KingbaseES&#8217;s support for complex types and pseudo-columns helps mitigate this.<\/li>\n<li>Operational Costs: Training for DBAs, changes in monitoring tools, and potential hardware upgrades.<\/li>\n<li>Risk Mitigation: The cost of downtime or data loss during migration. A well-planned migration to a compatible commercial database can reduce this risk.<\/li>\n<\/ul>\n<h3>TCO Comparison Framework<\/h3>\n<p>Without specific pricing data, a symmetrical comparison of TCO relies on the trade-off between licensing and labor:<\/p>\n<table>\n<thead>\n<tr>\n<th style=\"text-align:left\">Cost Component<\/th>\n<th style=\"text-align:left\">Oracle (Incumbent)<\/th>\n<th style=\"text-align:left\">KingbaseES (Commercial Alternative)<\/th>\n<th style=\"text-align:left\">Open-Source (e.g., PostgreSQL)<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td style=\"text-align:left\"><strong>Licensing<\/strong><\/td>\n<td style=\"text-align:left\">High (Processor\/Named User)<\/td>\n<td style=\"text-align:left\">Commercial (Defined terms)<\/td>\n<td style=\"text-align:left\">Low\/Free (but support costs vary)<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align:left\"><strong>Migration Labor<\/strong><\/td>\n<td style=\"text-align:left\">N\/A<\/td>\n<td style=\"text-align:left\">Moderate (High compatibility reduces effort)<\/td>\n<td style=\"text-align:left\">High (Significant refactoring often required)<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align:left\"><strong>Refactoring<\/strong><\/td>\n<td style=\"text-align:left\">N\/A<\/td>\n<td style=\"text-align:left\">Low (Supports complex PL\/SQL)<\/td>\n<td style=\"text-align:left\">High (Standard SQL only)<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align:left\"><strong>Support<\/strong><\/td>\n<td style=\"text-align:left\">High (Vendor included)<\/td>\n<td style=\"text-align:left\">High (Vendor included)<\/td>\n<td style=\"text-align:left\">Variable (Third-party or internal)<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align:left\"><strong>Risk Cost<\/strong><\/td>\n<td style=\"text-align:left\">Low (Mature ecosystem)<\/td>\n<td style=\"text-align:left\">Moderate (Requires validation)<\/td>\n<td style=\"text-align:left\">High (Community support risks)<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Key Insight: For enterprises with heavy PL\/SQL dependencies, the &quot;savings&quot; from open-source licensing can be quickly eroded by the high cost of refactoring and the risk of operational instability. KingbaseES offers a commercial model that may result in a lower overall TCO for legacy migrations by minimizing the labor and risk components.<\/p>\n<h2>Decision Matrix: Mapping Workloads to the Right Alternative<\/h2>\n<p>There is no universal &quot;best&quot; alternative to Oracle database. The optimal choice depends on the specific workload profile, the degree of legacy dependency, and the organization&#8217;s risk tolerance.<\/p>\n<h3>Conditional Recommendations<\/h3>\n<p>Choose KingbaseES if:<\/p>\n<ul>\n<li>Legacy PL\/SQL Dependency: Your application relies heavily on complex Oracle PL\/SQL packages, stored procedures, and triggers. KingbaseES&#8217;s support for RECORD types, <code>%TYPE<\/code>, <code>%ROWTYPE<\/code>, and pseudo-columns (<code>CURRVAL<\/code>, <code>NEXTVAL<\/code>) minimizes the need for code refactoring.<\/li>\n<li>Commercial Support Requirement: You require a defined vendor support model, warranty, and SLA, but want to avoid Oracle&#8217;s licensing costs.<\/li>\n<li>Data Integrity Focus: Your workload requires strict ACID compliance and enterprise-grade reliability without the risk of community-supported software.<\/li>\n<li>Migration Speed: You need to migrate quickly and want to leverage high compatibility to reduce the migration timeline.<\/li>\n<\/ul>\n<p>Choose PostgreSQL (or similar Open Source) if:<\/p>\n<ul>\n<li>Greenfield Development: You are building new applications and do not have legacy Oracle dependencies.<\/li>\n<li>Open-Source Preference: You prioritize open-source flexibility and have the in-house expertise to manage support and maintenance.<\/li>\n<li>Refactoring Tolerance: You are willing to invest significant time and resources to refactor Oracle-specific code to standard SQL.<\/li>\n<\/ul>\n<p>Choose Other Commercial Alternatives (e.g., SQL Server) if:<\/p>\n<ul>\n<li>Microsoft Ecosystem: Your infrastructure is heavily invested in the Microsoft stack (Windows, .NET, Azure).<\/li>\n<li>Specific Tooling: You require specific tooling or integrations that are better supported by Microsoft.<\/li>\n<\/ul>\n<h3>Final Assessment<\/h3>\n<p>For organizations seeking to replace Oracle, the decision should be driven by a symmetrical evaluation of compatibility, migration effort, and support. KingbaseES stands out as a commercial alternative that specifically targets the friction points of Oracle migration, namely the proprietary PL\/SQL ecosystem. However, it is not a &quot;one-size-fits-all&quot; solution.<\/p>\n<p>Enterprises must validate the specific compatibility of their custom Oracle features against KingbaseES before committing. The goal is to find the database that offers the lowest risk and TCO for the specific migration scenario, not one that is &quot;better&quot; than Oracle in every metric.<\/p>\n<h2>FAQ<\/h2>\n<h3>Is KingbaseES an open-source alternative to Oracle?<\/h3>\n<p>No. KingbaseES is a commercial database product. It is not open-source or source-available. It operates under a commercial license with defined terms, restrictions, and vendor support, distinguishing it from open-source alternatives like PostgreSQL.<\/p>\n<h3>What specific Oracle PL\/SQL features does KingbaseES support?<\/h3>\n<p>KingbaseES supports a wide range of Oracle PL\/SQL syntax, including control flow statements (<code>IF-THEN-ELSE<\/code>, <code>CASE<\/code>), loop structures (<code>LOOP<\/code>, <code>WHILE<\/code>, <code>FOR<\/code>), cursor management (<code>REF CURSOR<\/code>, <code>RETURNING INTO<\/code>), and collection handling (<code>BULK COLLECT<\/code>, associative arrays). It also supports complex data types like <code>RECORD<\/code>, <code>%TYPE<\/code>, and <code>%ROWTYPE<\/code>.<\/p>\n<h3>How does KingbaseES handle Oracle pseudo-columns like CURRVAL and NEXTVAL?<\/h3>\n<p>KingbaseES provides direct support for Oracle pseudo-columns, including <code>CURRVAL<\/code>, <code>NEXTVAL<\/code>, and <code>LEVEL<\/code>. This allows applications that rely on these pseudo-columns for sequence management and hierarchical queries to function with minimal modification.<\/p>\n<h3>What is the migration effort for complex Oracle stored procedures compared to PostgreSQL?<\/h3>\n<p>Migration effort to KingbaseES is generally lower than to PostgreSQL for applications with heavy PL\/SQL dependencies. Because KingbaseES supports proprietary PL\/SQL syntax and complex data types, it reduces the need for extensive code refactoring. In contrast, PostgreSQL typically requires converting Oracle-specific logic to standard SQL or PL\/pgSQL, which can be labor-intensive.<\/p>\n<h3>Does KingbaseES offer high availability similar to Oracle RAC?<\/h3>\n<p>KingbaseES supports high availability configurations, which is essential for enterprise OLTP workloads. However, the specific architectural details (such as failover times or node limits) may differ from Oracle RAC. Enterprises should validate the specific HA configuration against their operational requirements and SLAs.<\/p>\n<hr \/>\n<p><strong>\ud83d\udca1 More Resources<\/strong><\/p>\n<p>If you would like to dive deeper into KingbaseES and its application practices across various industries, we have compiled the following official resources to help you get started quickly and develop and operate with efficiency:<\/p>\n<ul>\n<li><a href=\"https:\/\/bbs.kingbase.com.cn\/\">Kingbase Community<\/a>: A one-stop interactive platform for technical exchanges, Q&amp;A, and experience sharing\u2014join forces with fellow DBAs and developers.<\/li>\n<li><a href=\"https:\/\/www.kingbaseglobal.com\/Solution-Oracle.html\">Kingbase Solutions<\/a>: One-stop full-stack database migration and cloud-native solutions, supporting smooth migration of multi-source heterogeneous data, ensuring high availability, real-time integration, and sustained high performance.<\/li>\n<li><a href=\"https:\/\/www.kingbaseglobal.com\/Customers.html\">Kingbase Case Studies<\/a>: Real-world user scenarios and implementation outcomes, showcasing KingbaseES&#8217;s outstanding capabilities in high availability, high performance, and IT adaptation.<\/li>\n<li><a href=\"https:\/\/docs.kingbase.com.cn\/en\">Kingbase Documentation<\/a>: Authoritative and comprehensive product manuals and technical guides, covering the entire lifecycle from installation and deployment to development, programming, and operations management.<\/li>\n<li><a href=\"https:\/\/www.kingbaseglobal.com\/Download.html\">Free Download<\/a>: Get the latest installation packages, drivers, tools, and patches, supporting multiple platforms and domestic chip architectures.<\/li>\n<li><a href=\"https:\/\/www.kingbaseglobal.com\/blog\/\">Digital Construction Encyclopedia<\/a>: Covers digital strategy planning, data integration, metrics management, database visualization applications, and more to empower enterprise digital transformation.<\/li>\n<\/ul>\n<p><strong>Open Source Resources:<\/strong><\/p>\n<ul>\n<li><a href=\"https:\/\/github.com\/hgsandy\/Kingbase-docs\">GitHub &#8211; Kingbase-docs<\/a>: Kingbase documentation open-source repository\u2014Stars and contributions are welcome.<\/li>\n<li><a href=\"https:\/\/gitee.com\/hgsandy\/kingbase-docs\">Gitee &#8211; Kingbase-docs<\/a>: Domestic mirror repository for Kingbase documentation for faster access.<\/li>\n<\/ul>\n<p>Welcome to explore the resources above and begin your Kingbase journey!<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Oracle Alternatives: Compatibility and Migration Risk The PL\/SQL Compatibility Reality: Syntax vs. Semantics In the enterprise landscape, the search for an alternative to Oracle database often begins with a common&#8230;<\/p>\n","protected":false},"author":1409,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"meta_description":"Symmetrical comparison of Oracle alternatives for enterprise OLTP: PL\/SQL syntax support, RAC migration, licensing, TCO, and migration risk.","_kingbase_seo_description":"","footnotes":""},"categories":[1],"tags":[],"class_list":["post-756","post","type-post","status-publish","format-standard","hentry","category-uncategorized"],"_links":{"self":[{"href":"https:\/\/www.kingbaseglobal.com\/blog\/wp-json\/wp\/v2\/posts\/756","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.kingbaseglobal.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.kingbaseglobal.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.kingbaseglobal.com\/blog\/wp-json\/wp\/v2\/users\/1409"}],"replies":[{"embeddable":true,"href":"https:\/\/www.kingbaseglobal.com\/blog\/wp-json\/wp\/v2\/comments?post=756"}],"version-history":[{"count":3,"href":"https:\/\/www.kingbaseglobal.com\/blog\/wp-json\/wp\/v2\/posts\/756\/revisions"}],"predecessor-version":[{"id":1068,"href":"https:\/\/www.kingbaseglobal.com\/blog\/wp-json\/wp\/v2\/posts\/756\/revisions\/1068"}],"wp:attachment":[{"href":"https:\/\/www.kingbaseglobal.com\/blog\/wp-json\/wp\/v2\/media?parent=756"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.kingbaseglobal.com\/blog\/wp-json\/wp\/v2\/categories?post=756"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.kingbaseglobal.com\/blog\/wp-json\/wp\/v2\/tags?post=756"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
