Process Data using DSL (from Fraktal SAS Programming)

Data Repositories

In 21st century data processing data are kept in databases managed by active server software already listed elsewhere in these guidelines. Hence, the most common scenario met by SAS coders is working on data which are already in tabular format. These are not as aged as, but quite near to the concept SAS uses for its proprietary table format known as SAS datasets. Having emerged in 1990, the SAS Multiple Engine Architecture provides a continuously growing number of means to seamlessly integrate data tables managed by 3rd party database servers. To the SAS programmer these means are known as engines that provide mainly read/write interaction with most data sources used in professional IT.

See chapter DBMS Interaction for technically detailed information on this topic.

As a result from the forementioned situation we do not put emphasis on data server technology nor vendor when talking about processing data sources of tabular format. Everthing behind a library reference is assumed to be of compatible structure and, hence, treated equally throughout these guidelines.
