Creating data source connections
Once you have specified an application server, you can
add data source connections to the environment file.
A data source is a logical representation of physical storage. It uses a CRUD (Create, Read, Update, and Delete) interface to interact with data objects in the physical storage. Data sources are configured and bound to physical storage addresses through connections. The following data source connections are available:
- File Storage Connection
- Allows you to work with persisted instances of data in a file system.
- Relational Database Connection
- Allows you to work with persisted instances of data in a relational database. Refer to the Release Notes document for a list of supported relational databases.
- Service Data Source Connection
- Allows you to work with persisted instances of data using a collection of services, such as web services and stored procedures. The process to create a service data source connection differs from that of other connection types. Refer to Configuring a service data source connection for instructions on how to create this connection.
- XML Connection
- Allows you to work with persisted instances of data in an XML file.
Data source connections can be added to an environment in any order. The number of connections that can be added is limited only by the number of available data sources. Refer to the NexJ Framework Metadata Reference for detailed information on the elements and attributes of data source connections.
