Generators usually uses templates with parameterized attributes. Based on the input data for parameterized attributes and using templates large number of objects of the same type is generated. For example transformations filling some of the data warehouse layer represent such objects.

    Informatica code generator reduces development costs by automated generating ETL using users templates. GTL Generator permits to generate: Source and target objects for transformed data (Informatica sources and targets). Mapping with transformations. Sessions and workflows for generated mappings. Auxiliary files for mapping – parametrical files and definition plans for external components. SQL code (BTEQ script, saved procedures) based on model input. Generation results in Informatica are PowerCenter objects saved in XML which may be imported directly to the Informatica PowerCenter repository. Tool architecture Informatica code generator consists of three basic components: Application GTL Generator (Java) installed on the workstation. Mapping…
