ExTL

ExTL, which stands for Export Transformation Language, is a data transformation language developed by IBM. It is designed to process and transform data structures, particularly hierarchical and relational data, into different formats. ExTL is often used in enterprise environments for data integration, data warehousing, and application-to-application data exchange.

The language provides a set of commands and functions that allow users to define rules for extracting, mapping, and restructuring data. It supports various data formats, including XML, CSV, and fixed-length records, making it versatile for different data integration scenarios. ExTL's syntax is procedural, enabling users to specify a sequence of operations for data manipulation.

Key features of ExTL include its ability to handle complex data transformations, such as data aggregation, conditional logic, and data validation. It also offers support for character encoding conversions and string manipulation. ExTL is often integrated with other IBM software products, such as IBM DataStage and IBM InfoSphere DataStage, to facilitate end-to-end data integration solutions. The primary purpose of ExTL is to bridge the gap between disparate data sources and formats, ensuring that data can be consistently processed and utilized across an organization.
