You can enable version control in the repository. It is a separate multi-threaded process, and it fetches, inserts and updates the metadata inside the repository. With the version control feature, you can maintain different versions of the same object. The mappings and objects that we create in these client tools are saved in the Informatica repository which resides on the Informatica server.
It is also responsible for maintaining consistency inside the repository metadata. To manage a repository there exists an Informatica service called Repository Service. Ethical Hacking Informatica Jenkins. To use the flat file in Informatica, its definitions must be imported similar to as we do for relational tables.
Also, a repository service can execute on multiple nodes to increase the performance. Accounting Business Analyst Cloud Computing.
So the client tools must have network connectivity to the server. It consists of database tables that store metadata. The powercentwr can be launched using web browsers.
