part of primary data warehouse which is required by a specific domain or department. Data Warehouse Data Mart Data Warehouse Data Mart Figure 1.1 A data warehouse does not necessarily use a dimensional model, since it is partly normalized RDBMS, but data marts are multidimensional cubes. This connection gives arise to two concepts, ROLAP and MOLAP. ROLAP is an implementation based on a relational database, in our case which is a primary data warehouse, and MOLAP is an implementation based

“SEQUEL” was a trademark of the UK-based Hawker Siddely aircraft company. In the late 1970s, Relational Software Inc. (now Oracle Corporation) saw the potential of the concepts described by Codd, Chamberlain, and Boyce and developed their own SQL-based RDBMS with aspirations of selling it to the U.S. Navy, Central Intelligence Agency, and other U.S. government agencies. In June 1979, Relational Software Inc. introduced the first commercially available implementation of SQL, Oracle V2(Version 2) for VAX

atablespace of the database. The data of each object is physically contained in one or more of the tablespace's datafiles. For some objects (such as tables, indexes, and clusters) a database administrator can specify how much disk space the Oracle RDBMS allocates for the object within the tablespace's datafiles. When it processes DML requests, Teradata Database accesses the information it needs from data dictionary tables using internal express-request transactions that place READ locks on row
