Use of the same program at a time by many users sometimes lead to the loss of some data. A data warehouse is constructed by integrating data from multiple heterogeneous sources that support analytical reporting, structured and/or ad hoc queries, and decision making. The user writes some specific commands in a database access language and submits these to the database. Procedure are a set of instructions and rules that help you to use the DBMS. Constraints are the rules enforced on data columns on a table.
