DSNDataSourceN

DSNDataSourceN is a programmatic identifier used in software systems that manage multiple data sources. It denotes the data source name (DSN) associated with the Nth data source in a collection or batch configuration. The term is not part of the official ODBC specification but appears in various codebases, configuration schemas, or code generation templates that support multi-DSN setups.

In practice, DSNDataSourceN is used to reference or retrieve the name of a specific data source within a set, enabling dynamic selection, mapping, or iteration over sources. For example, in a script that builds connection strings for several databases, DSNDataSource1 might contain “SalesDB,” DSNDataSource2 “HRDB,” and so on. It serves as a convenient label for accessing a particular DSN entry without hardcoding names throughout the codebase.

Syntax and scope: The exact representation varies by language or framework. DSNDataSourceN may be implemented as entries in a dictionary, as a structured field in a config object, or as elements in an array. Some codebases index from 0, others from 1; the documentation should specify the indexing convention and any data type restrictions (string values, allowed characters, length limits).

Relationship and limitations: DSNDataSourceN works alongside DSN, data source names, and connection strings. It is a convenience alias for referencing a named data source within a collection. Because it is not a standardized term, its availability and behavior depend on the library, framework, or platform in use.
