Informatica Architecture is classified into two components, they are
In the server, components consists of two servers:
• Repository server
• Informatica server
Especially Repository server used to maintain the connections with power center and clients for power center repository and separate in a multi-threaded process. Insert the metadata inside repository and updates. Responsible the fetch data and maintain the consistency inside in repository metadata.
Informatica server an executing engine in tasks that created in Informatica and a user executes in workflow Informatica suggests integration service execute the workflow. Similarly It reads Informatica server workflow and its repository once execution completed. In particular the task status updated after completion in execution the workflow log and session log generated.
Client Component: In the client, a component divided into four ways they are:
• Repository Manager
Generally Clients access to repository by using repository service only and managing a repository exists in informatica server called repository server. Conversely Single repository service handles only one repository. However It will execute on multiple nodes, to increase the performance. For example it use locks on the object so multiple users will not modify the same object at the same time.
In repository, Objects that created in the following three states.
Impacted objects is a child object that invalid in a mapping while using a reusable transformation object. Which becomes invalid in the mapping it will marked as impacted.
Valid objects used to correct the syntax on Informatica and execution of workflows.
In other words Invalid objects do not adhere to the standard or specified rules . If any object saved in Informatica, At the same time it will check the syntax and properties valid or not.

• In organization migrate the existing legacy system mainframe to a new database system, so it migration on existing data into the system will performed.
• Enterprises maintenance Data Warehouse for an ETL tool is to move data from the production system to Warehouse.
• Data is used to integrate from several systems to multiple databases and informatica uses a file based system.
• Informatica will be used as a data cleansing tool.
Informatica comes into the picture, whenever we have a data system containing at the back end we need to perform particular operations on the data. For instance It may clean up of data and modify the data base. Consequently On certain rules or modify the huge data from one system to another system.
Similarly Informatica provide a rich set of operations on at row level data for the integration of data from multiple structure. Scheduling of data operation, semi-structured or unstructured systems . In the same fashion it also contains the feature of metadata and the information about the process and data operations are preserved.
