Microsoft SQL Server 2008 introduces two new compression features (available in Enterprise and Developer editions) that are of interest to users with large databases.

These tables are linked by defined relations making it possible to combine data fromseveral tables upon request. Using a RDMS means it is possible to add, access, and process the data stored in your database. ‘SQL’ stands for “Structured Query Language” - the most common standardised language used to access databases.

Moscow ML implements Standard ML (SML), as defined in the 1997 Definition of Standard ML, including the SML Modules language and some extensions. Moreover, Moscow ML supports most required parts of the SML Basis Library. It supports separate compilation and the generation of stand-alone executables. This document explains how to use the Moscow ML system. A companion document, the Moscow ML Language Overview, summarizes Moscow ML syntax and the most common built-in functions [9]. Another companion document, the Moscow ML Library Documentation, describes in detail all Moscow ML library modules [10]. Get a copy of the Moscow ML system executables (see Section 20 for instructions) and unpack them in your home directory (under Unix) or in directory C:\ (under MS Windows and DOS).
