System tables of a geodatabase stored in Oracle

System tables of a geodatabase stored in Oracle
Release 9.3

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 an Oracle DBMS. You can use the links below to jump to a section of the list.

NOTE: The system tables should not be altered using anything other than the ArcGIS software.

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.

STATES

The STATES table contains the state metadata. It accounts for the states that have been created over time, and the creation time, closing time, parent, and owner of each state.

When a state is created, a state ID is assigned and a record is added to this table.

Field name	Field type	Discussion
STATE_ID	NUMBER(38)	A unique ID for this state, assigned by ArcSDE Primary key NOT NULL
OWNER	NVARCHAR2(32)	The user who created this state NOT NULL
CREATION_TIME	DATE	The date/time this state was created NOT NULL
CLOSING_TIME	DATE	The date/time that this state was closed
PARENT_STATE_ID	NUMBER(38)	This state’s parent's STATE_ID NOT NULL
LINEAGE_NAME	NUMBER(38)	References the state's lineage stored in the STATE_LINEAGES table NOT NULL

ST_COORDINATE_SYSTEMS

The ST_Coordinate_Systems table contains all coordinate systems registered with the Spatial Type. This table is updated when ArcSDE is installed and, when needed, upgraded. It can also be updated to include user-defined coordinate systems by using the ST_CSRegister function.

Along with the ST_SPATIAL_REFERENCES table, the ST_COORDINATE_SYSTEMS table describes coordinate systems and projections available to the ST_Geometry type.

Field name	Field type	Description
NAME	NVARCHAR2(128)	Coordinate system name
TYPE	NVARCHAR2(128)	Type of coordinate system: PROJECTED, GEOGRAPHIC, or UNSPECIFIED
DEFINITION	NVARCHAR2(2048)	Well-known text description of the coordinate system
ORGANIZATION	NVARCHAR2(128)	Name of the organization that defined the coordinate system
ID	NUMBER(38)	Coordinate system ID defined by the organization NOT NULL
DESCRIPTION	NVARCHAR2(256)	Description for the coordinate system indicating its application

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.

Field name	Field type	Description
OWNER	NVARCHAR2(32)	Schema name owning the table NOT NULL
TABLE_NAME	NVARCHAR2(32)	Unqualified table name having one or more spatial types NOT NULL

PROPERTIES	NUMBER(38)	A bit mask containing application information such as entity, table status, load/normal mode, table, or view
SRID	NUMBER(38)	Spatial reference value from ST_SPATIAL_REFERENCES table NOT NULL
GEOM_ID	NUMBER(38)	Uniquely defines a record; used as reference key to the index_id in ST_GEOMETRY_INDEX table NOT NULL

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');

OWNER, TABLE_NAME, and COLUMN_NAME uniquely identify an ST_SPATIAL_INDEX domain index.

Field name	Field type	Description
OWNER	NVARCHAR2(32)	Schema owner.
TABLE_NAME	NVARCHAR2(32)	Unqualified table name.
COLUMN_NAME	NVARCHAR2(32)	Name of the geometry column.

CLUSTERING_FACTOR	NUMBER(38)	Indicates how ordered the rows in the table are based on the values of the index; if the CLUSTERING_FACTOR value is close to the number of blocks, the table is well ordered. 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.
DENSITY	NUMBER(38)	Average number of features per grid cell.
NUM_ROWS	NUMBER(38)	Number of rows in the table containing the ST_Geometry and ST_SPATIAL_INDEX.

USER_STATS	VARCHAR2(3)	Indicates whether statistics were entered directly by the user (YES) or not (NO).
ST_FUNCS	SDE.ST_FUNCS_ARRAY	User-defined operator selectivity and cost values; when set, defined values override derived selectivity and system-defined operator costs.

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.
