System tables of a geodatabase in DB2

The system tables for a geodatabase enforce geodatabase behavior, store information about the geodatabase, and keep track of the data stored in the geodatabase.

View a diagram of the ArcSDE geodatabase system tables.

You need Adobe Acrobat Reader to open the file.

The system tables and their contents should not be altered using anything other than ArcGIS software. However, you can use SQL to view the contents of the system tables.

Some of the geodatabase system tables contain XML columns. You can use the native XML queries of your database management system to query these columns. The whitepaper "XML Schema of the Geodatabase" defines the XML tags.

COLUMN_REGISTRY

The COLUMN_REGISTRY table manages all registered columns.

CautionCaution:

If you alter column definitions using a SQL interface, the records in the COLUMN_REGISTRY table are not updated. This may cause any subsequent exports of the data to fail.

MVTABLES_MODIFIED

The MVTABLES_MODIFIED table maintains the list of all tables that are modified in each state of the database. This information aids in quickly determining if conflicts exist between versions or states of the database.

The MVTABLES_MODIFIED table maintains a record of all tables modified by state. This information allows applications to determine which tables need to be checked for changes when reconciling potential conflicts between versions and states in the database.

Any time a feature class or table is modified in a state, a new entry is created in the MVTABLES_MODIFIED table. When two versions are reconciled, the first step in the process is to identify the states these two versions reference—the current edit version’s state and the target version’s state. From these states, a common ancestor state is identified by tracing back through the state lineage of these two versions.

ST_SPATIAL_REFERENCE_SYSTEMS

This view contains all spatial references available to the ST_Geometry type. Spatial tables must be referenced correctly for you to analyze them individually or combine them to see relationships. This means they must have a spatial reference and coordinate system.

The ST_SPATIAL_REFERENCE_SYSTEMS view contains the coordinate system and floating point-to-integer transformation values. Internal functions use the parameters of a spatial reference system to translate and scale each floating-point coordinate of the geometry into 64-bit positive integers prior to storage. Upon retrieval, the coordinates are restored to their original external floating-point format.

This view is a Spatial Extender view and is not stored in the ArcSDE administrator's (the sde user) schema.

VERSIONS

The VERSIONS table contains information about versioned geodatabases.

Each version is identified by a name, with an owner, description, and associated database state. This table defines the different versions that the database contains and provides a list of available versions to be presented to the user. These versions are used to access specific database states by the application. The version name and ID are unique.

When the VERSIONS table is first created by ArcSDE, a default version is inserted into the table. This default version is named DEFAULT, is owned by the ArcSDE administrator, and is granted PUBLIC access. The initial state_id is set to 0, and the description string reads Instance Default Version. Since the default version has been granted PUBLIC access, any user can change the state of the default.
