================================================================================= User-Defined Schema (UDS) in the context of Domain-Specific Languages (DSL) and Structured Query Language (SQL) refers to schemas that are defined by users rather than being fixed by the system. UDS allows users to specify the structure, types, and constraints of the data according to their specific needs and requirements. This flexibility can be crucial in domains where the data or its usage are specialized or require customization beyond the capabilities of standard schemas.
In DSLs, implementing UDS often involves creating a meta-language or using existing language features to define new data types, functions, and structures. In SQL, UDS might be implemented through SQL extensions or user-defined functions, types, and procedures that extend the capabilities of standard SQL. ===========================================
