Repositories

Big Data Management includes repositories to store data related to connections, source metadata, data domains, data profiling, data masking, and data lineage. Big Data Management uses application services in the Informatica domain to access data in repositories. The repositories involved in the process depend on the data store for your task.
Big Data Management includes the following repositories:
Metadata Manager repository
The Metadata Manager Service reads metadata from the Metadata Manager repository when you perform data lineage analysis on the metadata.
Model repository
The Model repository stores profiles, data domains, mapping, and workflows that you manage in the Developer tool. The Model repository also stores profiles, data domains, and mapping specifications that you manage in the Analyst tool.
Profiling warehouse
The Data Integration Service runs profiles and stores profile results in the profiling warehouse.
