  What are some examples of Informatica ETL programs? Some basic Informatica programs are: Mappings: A mapping is designed in the Designer. It defines all the ETL processes. Data are read from their original sources by mappings before the application of transformation logic to the read data. The transformed data is later written to the targets. Workflows: The processes of runtime ETL are described by a collection of different tasks are known as workflow. Workflows are designed in the Workflow Manager. Task: This is a set of actions, commands, or functions that are executable. How an ETL process behaves during runtime can be defined by a sequence of different tasks. Which development components of Informatica have the highest usage? There are many development components in Informatica. However, these are the most widely used of them: Expression: This can be used to transform data that have functions. Lookups: They are extensively used to join data.

  Passive transformation Passive transformation is a transformation that does not eliminate the number of rows, i. SQ stands for Source Qualifier transformation that selects the records from multiple sources, and the sources can be relational tables, flat files, and Informatica PowerExchange services. It is an active and connected transformation. When you add the source tables in mapping, then Source Qualifier is added automatically. It displays the transformation types, i. In the case of SQ transformation datatypes, source datatype does not match with the Informatica compatible datatype then the mapping will become invalid when you save it.

  Case Sensitive You can also enable the case-sensitive property; in such case, an integration service will give more priority to the uppercase characters than lowercase characters. Work directory Work directory is a directory where integration service creates temporary files while sorting the data. When data is sorted, then all the temporary files will be removed from the work directory. Distinct Output Rows This property is used by the integration service to produce the distinct output rows. Tracing Level The tracing level is a property that controls the number, type of sorter error, and status messages that integration service writes to the session log. Null Treated Low Enable this property when you want integration service treat null value lower than other value. Disable this property when you want to treat the null value higher than the other value. Aggregator transformation is a connected and active transformation.

  It is used to perform aggregate functions over a group of rows such as sum, average, count, etc. For example, if you want to calculate the sum of the salary of all the employees, then an aggregator transformation is used. Aggregator transformation uses the temporary main table to store all the records, and perform the calculations. Components of Aggregator transformation: Aggregate cache An integration service uses the aggregate cache to store the data until the aggregate calculation is completed. It stores the group values in index cache and row data in the data cache. Aggregate expression An aggregate expression is provided to the output port and output port can also contain non-aggregate expressions and conditional clauses. Group by port This property is used to create the groups. Groups can be input, output, or any variable port. Sorted input Sorted input property is used to improve the session performance.

  In order to use sorted input, you need to pass the data to aggregator transformation sorted by group by port either in ascending or in descending order. Filter transformation is an active and connected transformation. It filters out the rows which are passed through it, i. It applies the filter condition on the group of data. This filter condition returns an either true or false value. If the value is true means that the condition is satisfied, then data is passed through, and if the value is false means that the filter condition is not satisfied, then integration service drops the data and writes the message to the session log. Joiner Transformation is an active and connected transformation. It allows you to create the joins in Informatica, similar to the joins that we create in database. In joiner transformation, joins are used for two sources and these sources are: Master source Detail source In joiner transformation, you need to choose which data source will be Master, and which data source will be Detail.

  There are four types of joins used in a joiner transformation: Master outer join In Master outer join, the resultset contains all the records from the Detail source and the matching rows in the master source. This join will be similar to the Right join in SQL. Detail outer join In Detail outer join, the resultset contains all the records from the Master source and the matching rows in the Detail source. This join will be similar to the Left join in SQL. Full outer join In Full outer join, the resultset contains all the records from both the sources, i. Normal join In Normal join, the resultset contains only the matching rows between Master and Detail source. This join is similar to the inner join in SQL. Router transformation is an active and connected transformation. Router transformation is similar to the filter transformation as both the transformations test the input data based on the filters.

  In Filter transformation, you can apply only one filter or condition, and if the condition is not satisfied, then a particular is dropped. But in Router transformation, more than one condition can be applied. Therefore, we can say that the single input data can be checked on multiple conditions. Rank transformation is an active and connected transformation. It filters the data based on groups and ranks. For example, if you want to get top 3 salaried employees department wise, then this will be achieved by the rank transformation.
