With 9. Below diagram details various components used in 9. There are few points worth noting: Service Oriented Architecture means that various components within Informatica encapsulate core functionalities and these components are composed together to build various Informatica products.

Informatica follows a Model Driven Architecture where all the domain objects are modeled. Also, the core meta-models are shared across all Informatica products which help various tools to interact with each other. For example, with the help of such model Informatica Analyst tool can talk to Informatica Developer. Administrator Console: This is a web based platform where an administrator can setup and control how Informatica will be setup.

This involves setting up and maintenance of domain, nodes, and various services such as Repository Service. This tool also provides Security Control like adding groups, users and their access to repository. It is extensible through plug-ins for additional services. ISP supports single point of administration.

And, it allows integration with LDAP active directory. It provides a set of core services used internally, like Authentication Service, Name Services, and so on. The MRS provides automated persistence of models. It looks at the model to determine how to persist objects. The default persistence scheme can be customized. Repository capabilities are model agnostic. MRS allows you to add the model definitions dynamically. Like, adapter meta models. DIS plug-ins provide different data integration functionalities.

The different plug-ins are as follows: Profiling service plug-in translates profile into mappings SQL Service plug-in translates SQL into mappings Mapping Service executes data quality plans It provides common services to its plug-ins: request dispatch, thread pooling, and so on.

It is re-engineered to be lightweight and embeddable. It allows repository-less execution: In previous versions of PowerCenter, DTM connects to the repository to fetch the plan. However, now the mapping can be run without reading from the repository, like mapping stored to disk. It supports logical transforms, which are translated to executable transforms before execution. It allows different execution modes: single threaded and pipelined execution modes.

DTM comes up with optimal execution plan for mappings. Web Services: Informatica 9. You can publish logical data objects and transformations as Web Service end point.
