Informatica Architecture Tutorial

Vasics database systems are generally owned by other applications which create and maintain this data. Domain Configuration As mentioned earlier, domain is the basic administrative control in Informatica. Once open in a web browser it prompts for administrator login.

It is also responsible for maintaining consistency inside the repository metadata. It is the parent entity which consists of other services like integration service, repository service, and various nodes.

We import source definitions from the source and then connect to it to fetch the source data in our mappings. Once execution is complete, the status of the task 91 updated i.

For example in a mapping if you are using infofmatica reusable transformation, and this transformation object becomes invalid then the mapping will be marked as impacted. There are two types of services in Domain Service Manager: Invalid objects are those who does not adhere to the standard or rules specified. To use the flat file in Informatica, its definitions must be imported similar to as we do for relational tables. This service is responsible for loading data into the target systems.

It is a collection of nodes and services. Node is required to run services and processes for Informatica. Restart Period — It is the maximum number of seconds the domain spends powercsnter restart a service.

Integration Service Integration service is the executing engine for the Informatica, in other words, this is the entity which executes the tasks that we create in Informatica. So the client tools must have network connectivity to the server. When any object is saved in Informatica, it is checked whether its baasics and properties are valid or not, and the object is marked with the status accordingly.

After completion of execution, session log and workflow log is generated.

Relational — these types of sources are database system tables. Properties of the domain Click on the properties menu in the admin page to view the properties of the domain. This service is responsible for loading data into the target systems The integration service podercenter combines data from different sources For example, it can combine data from an oracle table and a flat file source.

In basids domain, you will also find a gateway node.

Node is a logical representation of a machine inside the domain. These objects can be used in the execution of workflows. Accounting Business Analyst Cloud Computing.

A single repository service handles exclusively only one repository. A flat file can be a comma separated file, a tab delimited file or fixed width file. Service manager manages domain operations like authentication, authorization, and logging. There can be different types of sources and can be located at multiple locations. These infornatica run on different nodes based upon the configuration.

The input to our mappings in Informatica is called source system. Database type — The type of database on which domain is configured. Based upon your requirement the target system can be a relational or flat file system.

It is a separate multi-threaded process, and it fetches, inserts and updates the metadata inside the repository. After login into the Informatica domain, the home page looks something like infodmatica.

The mappings and objects that we create in these client tools are saved in the Informatica repository which resides on the Informatica server. To manage a repository there exists an Informatica service called Repository Service. Powercenter designer, workflow inforjatica, a repository manager, and workflow monitor are the main client tools.

When the organization data is created at a Application service represents the server specific services like integration service, repository service, and reporting service.
