- WOW Metadata

WOW Metadata

[Pro or EE]  WOW metadata consists of data stored in database tables; the data is used by WOW when running the WOW Builder or WOW Applications. There are two types of WOW metadata, “project” metadata and “system” metadata.

Project metadata

Every time you create or edit an application or operation in the WOW Builder, that application/operation is saved in the project metadata. (Other information such as connection and field descriptors are also saved in the project metadata.) The project metadata is stored in one or more schema's on the metadata DB system. (A schema is a collection of tables on a database system. Some database vendors use different terminology and refer to a schema as a “library” or a “database”.) When view you the list of applications in the WOW Builder, those applications are part of the WOW metadata stored in a table in the current project schema. A different project schema would have a different list of applications, a different list of operation, etc. Although there may be many project schema's in a WOW installation, the WOW Builder can only show metadata from a single project schema at a time.

System metadata

There is also a system schema which WOW uses to stored internal information required for WOW to run. Typically a WOW installation will have a single system schema, even if there are multiple project schema's.
