  • 9 integration * intelligence * insight PowerCenter 8 Overview PowerCenter 8 Repository PowerCenter repository resides in a relational database. Repository database tables contain the instructions required to extract, transform, and load data. PowerCenter Client applications access the repository database tables through the Repository Service. The repository consists of database tables that store metadata. Metadata describes different types of objects, such as mappings or transformations, that we can create or modify using the Client tools. Integration Service uses repository objects to extract, transform, and load data. The repository also stores administrative information such as user names, passwords, permissions, and privileges. we add metadata to the repository tables when you perform tasks in the PowerCenter Client application, such as creating users, analyzing sources, developing mappings or mapplets, or creating workflows. The Integration Service reads metadata created through the Client application when you run a workflow. It also creates metadata, such as start and finish times of a session or session status.
