what is the difference between repository & Intergration service
what is the difference between repository & Integration service?
Repository: consist of original data base tables which are also called as system tables and metadata objects.
Ex:Actual source data (customers data,employee data,sales data)
Repository service: Repository service is responsible for inserts,updates,deletes and retrieve metadata from Repository. so it will work like mediator between the Repository and Integration Service(client components).
Ex: if you want to extract the data from Repository(actual data) at run time through Integration service you'll get an error because IS doesn't understand the System tables directly so you will need Repository service to handle inserts,updates,deletes and retrieve the data from Repository.
Integration Service: IS is responsible for executing the ETL Objects and performs Extraction,Transformation and Loading at Run time(while executing the session).IS needs Original database objects using objects we can move the data from source to target as per the requirements.
Ex: if you have a business requirements like calculations and conversions all these done by the IS.
