In a Data Flow Diagram, we focus on the interactions between the system and external parties, rather than the internal communications among interfaces. Therefore, data flows between interfaces and the data stores used are considered to be out of scope and should not be shown in the diagram. Do...
The figure below shows a context Data Flow Diagram that is drawn for a railway company's Customer Service System. It contains a process (shape) that represents the system to model, in this case, the "CS System". It also shows the participants who will interact with the system, called the...

This section explains the methods used to load the initial data in OUAW through the Oracle Database feature DBMS_DATAPUMP to bring existing historical data from the source database to the replication schema. There are three different modes to synchronize the initial source data with the target:...
JimMelton,StephenBuxton, inQuerying XML, 2006 8.2.1Databases A database, according to the Wikipedia,1is “an information set with a regular structure.” A database system, or database management system (DBMS), is thus (for our purposes, at least) a computer system that manages a computeriz...
A database is a structured set of data held in a computer, most often a server. Databases use a database management system (DBMS) that interacts with users, similar to a lookup table. Modern databases are designed to allow for the creation, querying, updating, and administration of the dat...
Use Lucidchart to visualize your database as an entity relationship diagram. Our database design tool supports DBMS platforms such as MySQL, Oracle, PostgreSQL, and Microsoft SQL Server.
Another use case that offers considerable value is that of handling database stored procedures in a data virtualization layer, as opposed to embedding them within the particular brand of DBMS. Placing data base stored procedures in the data virtualization layer provides complete flexibility to transitio...
