used to temporarily store data while it is being moved from one place to another. Typically‚ the data is stored in a buffer as it is retrieved from an input device (such as a microphone) or just before it is sent to an output device (such as speakers). However‚ a buffer may be used when moving data between processeswithin a computer. This is comparable to buffers in telecommunication. Buffers can be implemented in a fixed memory location in hardware—or by using a virtual data buffer in software‚ pointing

4.3 DATA FLOW DIAGRAM A data flow diagram is a graphical technique that depicts information flow and transforms that are applied as data move from input to output. The DFD is also known as Data Flow Graph or Bubble Chart. The DFD is used to represent increasing information flow and functional details. Also DFD can be stated as the starting point of the design phase that functionally decomposes the requirements specifications down to the lowest level of detail. A Level 0 also called a fundamental

will be comparing and contrasting transactional databases and data warehouses‚ demonstrating the similarities and differences between them both. I will do this by first defining these database systems and the reason for their use. I will also be using key relevant theories and tools to back up my findings‚ to argue their differences and similarities as efficiently as possible. Where similarities between transactional databases and data warehouses do exist they are in the areas of information storage
