One of the main changes in the development of gvSIG 2.0 has been the replacement of all previous data access methods with a new API and implementation, namely the DAL (Data Access Library).

This API combines access to both tabular and geometric data, in addition to defining a common core API between vector and raster data.

For more information about using the API, as well as the development of data providers, consult the `DAL development guide`__.
