A data dictionary is a file that defines the basic organization of a database. A data dictionary has a list of all files in the database‚ the number of records that are in each file‚ the names and types of each field. The data dictionary is hidden from users so that it is not accidentally destroyed. The data dictionary only keeps bookkeeping information and does not actually contain any data from the database. The database management system cannot access data from the database without a data dictionary

The Working Memory Model (WMM) is a theory by Baddeley and Hitch in 1974. The theory replaces the idea that there is a single Short Term Memory (STM) from Atkinson and Shiffrin (1968)‚ it suggests that the STM is a flexible multi-component system. The WMM suggests that the STM is controlled by the Central Executive (CE) which controls attention‚ planning and synthesising information. The Central Executive is a flexible system which means it can process audio‚ visual and sound information‚ it also

DATA FLOW DIAGRAM Group#7 Nugao Oserin Obongen The Data Flow Diagram (DFD) • a graphical representation of the flow of data through an information system. It enables you to represent the processes in your information system from the viewpoint of data. The DFD lets you visualize how the system operates‚ what the system accomplishes and how it will be implemented‚ when it is refined with further specification. • Data flow diagrams are used by systems analysts to design information-processing systems
