![]() ![]() Pipeline lookup: It performs lookup on application sources.Relational or flat file lookup: It performs lookup on relational tables.There are four different types of lookup transformation: What are the types of lookup transformation? In general, however, there can be any number of repositories.ħ. In Informatica Workflow Manager, how many repositories can be created?ĭepending upon the number of ports that are required, repositories can be created. It behaves as Left Outer Join while connecting with the databaseĬommunity support is restricted to the underscore template.Ħ. Users can restrict the number of rows while reading relational tables Users cannot restrict the number of rows while reading relational tables Differentiate between Joiner and Lookup transformations. It generates true or false values based on conditions.ĥ. It is added close to the source to filter out the unwanted data and maximize performance. Filter Transformation: It filters rows within a mapped data from any source. ![]() Also, Standard SQL is used by the filter condition for executing in the database. It minimizes the number of rows while mapping to enhance performance. Source Qualifier Transformation: It filters rows while reading data from a relational data source.There are two ways to filter rows in Informatica, they are as follows: While integrating data from various heterogeneous systems including multiple databases and file-based systemsĤ.When enterprises set up their data warehouse.When organizations migrate from the existing legacy systems to new database systems.There are many typical use cases of Informatica, but this tool is predominantly leveraged in the following scenarios: Mention some typical use cases of Informatica. This tool allows users to connect and fetch data from different heterogeneous sources and subsequently process the same.įor example, users can connect to a SQL Server Database or an Oracle Database, or both, and also integrate the data from both these databases to a third system.ģ. InformaticaPowerCenter is an ETL/data integration tool that has a wide range of applications. The lookup transformation is created with the following type of ports:.One can use multiple lookup transformations in a mapping. ![]()
