When business procedure principles are defined or described in a brief or precise and clear manner it can be understood as business role. The entity relationship model is easier to examine structures graphically than to describe them in text, database designers prefer to use a graphical tool in which entities and their relationships are pictured. Represents reality the usage of nicely defined photos and rules. A data model whose basic modeling structure is an object. The practical significance of data dependence is the difference between the logical data format (how the human being views the data) and the physical data format (how the computer "sees" the data). What are the basic characteristics of a NoSQL database? acts as the interface between the user application. Translators can help businesses climb the analytics learning curve quickly and roll out more use cases than they might otherwise.
