3.4 Data Source/Query Tree

The 'Data Source' node in the Asset panel lists the available data sources, together with their associated queries, models, and VPMs.

 

A data source provides connection information for a database. The information needed varies depending on the type of the database (e.g., a relational database requires a driver and URL). For more complex data sources, the data source objects also contain the meta-data information. The following types of datasources are supported.

 

Relational Databases (JDBC: Oracle, DB2, MySql, SQL Server, Sybase, Access, etc.)

 

XML Data Source

 

Multidimensional Databases (XMLA)

 

Text Data Source (CSV, Tab-delimited)

 

Web Service Data Source (SOAP)

 

Java Object Data Source

 

SAP Data Source

Relational (JDBC) data sources may also have associated data models (discussed in the following sections). A data source can have multiple data models, but each data model can only use one data source. Likewise, each query is associated with one data source.
