System tables of a geodatabase stored in Oracle

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

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.

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.

Upon retrieval, the coordinates are restored to their original external floating-point format.

Each geometry column of the GEOMETRY_COLUMNS table is associated with a spatial reference system, the information for which is stored in the SPATIAL_REFERENCES table. The columns of this table are those defined by the OpenGIS SQL Specification (SRID, SRTEXT, AUTH_NAME, and AUTH_SRID) and those required by ArcSDE for internal coordinate transformation.

STATE_LINEAGES

The STATE_LINEAGES table stores the lineage of each state. A new lineage name is created for each version. Each time a state is added, the lineage name and the state ID are added. When a state is added that is a new version, the ancestry state lineage of the parent state is added with the lineage name.

To return the correct view of a version, its states lineage is queried to identify all the states that recorded each change made to that version. From this list of states, the table rows that correctly represent the version can be determined.

ST_GEOMETRY_COLUMNS

This table holds the schema, geometry type, and spatial reference information for every ST_Geometry column created or added to a table object or view. Inserting ST_Geometry column information to this table is done using stored procedures to register/unregister tables or views. The table/column metadata must be registered to this table before creating a spatial index.

Creating a table with an ST_Geometry column does not insert ST_Geometry metadata. When you create a spatial index on a table, an entry will be inserted in the ST_GEOMETRY_COLUMNS and ST_GEOMETRY_INDEX tables.

This table is used to perform selections and DML metadata operations. Stored procedures are used to insert and delete entries from the ST_GEOMETRY_COLUMNS table.

ST_GEOMETRY_INDEX

This table holds the spatial index information for an ST_Geometry column. The spatial index for an ST_Geometry type is a domain index referred to in the CREATE INDEX statement.

Grid sizes and SRID are defined in the PARAMETERS clause of the CREATE INDEX statement. When using ALTER INDEX REBUILD, the SRID value should not be changed. If it is, the SRID values for all features will also need to be updated in a separate table UPDATE statement. To specify grid sizes and an SRID, use the st_grids and st_srid keywords:

CREATE INDEX shape_idx1 ON SCOTT.PARCELS (shape) 
INDEXTYPE IS SDE.ST_SPATIAL_INDEX
PARAMETERS('st_grids=1,0,0 st_srid=1');

In this case, the index entries in a single leaf block tend to point to rows in the same data blocks. If the CLUSTERING_FACTOR value is near the number of rows, the table is randomly ordered, in which case it is unlikely the index entries in the same leaf block point to rows in the same data blocks.

ST_SPATIAL_REFERENCES

This table 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_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.

Along with the ST_COORDINATE_SYSTEMS table, the ST_SPATIAL_REFERENCES table describes coordinate systems and projections available to the ST_Geometry type. Included in this table schema are scale and offsets for coordinates (x,y,z) and measures (m). This information is used to convert decimal values into integers and negative values into positive values for storage and performance reasons.

The ST_SPATIAL_REFERENCES table is prepopulated with spatial references defined by the European Petroleum Survey Group (EPSG). The EPSG codes are used for the spatial reference identifier (SRID) to make it easier to share data across databases. Other spatial references get added to the table when you import data if the incoming spatial reference does not match an exisitng spatial reference.

These versions are used to access specific database states by the application. The version name and ID are unique.

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.
