With the increase in availability of databases, data needed by a user are frequently in separate autonomous databases. The logical properties of such data differ from the classical ones within a single database. In particular, they call for new functions for data manipulation. MDSL is a new data manipulation language providing such functions. Most of the MDSL functions are not available in other languages.
