Datasources

(datasources)

Overview

Datasources in Servoy provide a structured way to interact with various types of data sources, such as database tables, in-memory tables, views, and stored procedures. These datasources are accessible through the datasources efficient development.

Datasources include types like DBDataSource, MemDataSource, ViewDataSource, SPDataSource, and MenuDataSource, each catering to a specific use case. For example, db is used for server/table-based data sources, mem for in-memory tables, and view for view foundset data sources. Stored procedures are managed under the sp property, with server-side configuration enabling their use. The menu property handles menu-related datasources.

For details related to datasources, refer to the specific sections in the Servoy documentation:
