ISO/IEC 9075-3:2023 defines Information technology - Database languages SQL - Part 3: Call-Level Interface (SQL/CLI), a technical reference for applications that need structured access to SQL database services through a standardized interface. It is relevant for teams evaluating database connectivity, integration behavior, and documented evaluation of software components that rely on consistent client-side database calls. As a derived document connected to ISO/IEC 9075, ISO/IEC 9075-3:2023 is useful when engineering, procurement, or compliance workflows require clarity on how SQL-based systems are accessed and validated across platforms.

ISO/IEC 9075-3:2023 standard overview

This part of the ISO/IEC 9075 series focuses on the Call-Level Interface for SQL, which generally supports application programs that communicate with relational database systems through a defined programming interface. For technical review and compliance preparation, it can help organizations assess whether database access behavior aligns with expected implementation practices, interoperability needs, and software quality workflows. ISO/IEC 9075-3:2023 is often consulted alongside related SQL documentation when teams perform technical validation or compare vendor-supported interfaces during procurement.

Applications of ISO/IEC 9075-3:2023

Typical use cases include software development, database integration testing, enterprise application deployment, and engineering documentation for systems that depend on SQL connectivity. It may also support laboratory evaluation and verification activities where consistent call-level behavior must be checked across different database environments. Organizations involved in data-driven platforms, middleware, client-server applications, and compliance-oriented software procurement may use ISO/IEC 9075-3:2023 as a reference point when reviewing interface compatibility and operational consistency.

Why ISO/IEC 9075-3:2023 matters

Reliable call-level database access is important for interoperability, testing consistency, and risk reduction in software environments that depend on SQL services. By providing a common reference for interface behavior, ISO/IEC 9075-3:2023 can help teams structure conformity assessment work, improve technical assessment outcomes, and support quality assurance during development or deployment. It is also useful when procurement teams need to compare supplier capabilities against a documented compliance reference for database connectivity.
