2) Repository API
- The ATG Repository API (atg.repository.*) is the foundation of persistent object storage, user profiling, and content targeting in ATG products.
- A repository is a data access layer that defines a generic representation of a data store. Application developers use this generic representation to access data by using only interfaces such as Repository and RepositoryItem.
- Developers use repositories to create, query, modify, and remove repository items. A repository item is like a JavaBean, but its properties are determined dynamically at runtime.
- This goal is achieved through three main conceptual parts of the Repository API:
- Repository items
- Item descriptors
- Repository queries
