Note:This topic was updated for 9.3.1.

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

To see a diagram of the geodatabase system tables, click here. (You need Adobe Reader to open this file.)

The following is an alphabetical list of the geodatabase system tables as they appear in a PostgreSQLdatabase management system (DBMS). You can use the links below to jump to different sections of the list.

This table is defined by the OpenGIS SQL specification and may be updated by other applications with geometry columns not managed by ArcSDE. When a new Geometry column is created in an OpenGIS compliant format, the fully qualified table, column name, and spatial reference ID (SRID) are added to the sde_geometry_columns table.

Each geometry column is associated with a spatial reference system. ArcSDE stores information on each spatial reference system in the sde_spatial_references table.

sde_mvtables_modified

The sde_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 sde_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.

Anytime a feature class or table is modified in a state, a new entry is created in the sde_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.

sde_spatial_references

The sde_spatial_references table 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.

Each geometry column of the sde_geometry_columns table is associated with a spatial reference system, the information for which is stored in the sde_spatial_references table. The columns of this table are those defined by the OpenGIS SQL specifications (srid, srtext, auth_name, and auth_srid) and those required by ArcSDE for internal coordinate transformation. The spatial reference system identifies the coordinate system for a geometry and gives meaning to the numeric coordinate values for the geometry.

Unlike the other system tables, this table is not stored in the SDE user's schema; it is stored in the public schema. This is necessary to allow data to successfully restore spatial data.
