Creating a Data Store
Concept Procedure
 
 
 

Features are stored in a data store, which is a collection of feature classes in a single data storage location. To add a feature to your map, you connect to its data store and select each feature class to include.

The main reason to create a new data store is to migrate existing data to the new FDO provider, or to create new data in that provider format.

You can create new data stores for database FDO Providers (Microsoft SQL Server, SQL Server Spatial, MySQL, or Oracle) and file-based FDO Providers (SDF or SHP) from within AutoCAD Map 3D if you have the necessary privileges for the target database or directory. After you create a data store, you can define or import a schema for it, which specifies the feature classes available in that data store and their properties.

Before creating a database data store, make sure you have created a user for the data store with the proper privileges.

To overwrite an existing data store, you must first delete the old one. For data stores from database FDO Providers, use DBMS-specific tools to drop existing tables.

After you create a data store and define a schema for it, AutoCAD Map 3D users can create, store, and access geospatial data in that data store.

If you have DWG data that you want to move to a feature source, see Migrating DWG Data to GIS.

When you create a data store, you specify the minimum and maximum X and Y spatial extents for new data store in the Create Data Store Dialog Box. This is especially important if you later use Bulk Copy to move data to that data store. You must make sure that the data you are moving are inside the extents of the destination data store. MySQL and Oracle support expanding the extents automatically if incoming data are beyond the scope of the extents.
