Database Schemas for WCS

For Web Coverage Service purposes, this document refers to Oracle AI Database schemas that can be user schemas and/or WCS schemas.

• A user schema is any schema used to store GeoRaster objects.

  In some examples used in this document, the schema of a database user named SCOTT is a user schema.

• A WCS schema is any database schema with an SDO_WCS_COVERAGE table, which must be created using the WCS Administration Console or the SDO_WCS.Init procedure. The coverage information is stored in a WCS schema.

  In some examples in this document, the schema of a specially created database user named WCS_USER is the WCS schema.

A given Oracle AI Database schema can be a user schema, a WCS schema, or both a user schema and a WCS schema.

Each WCS instance requires a WCS schema configured as a JDBC data source in the application container. Generally, only one WCS schema is configured for a specific database, but many WCS instances can be configured for use with the same database.
