Differentiate between database management system and information retrieval system by focusing on their functionalities.
A database management system in the main software tool of the database management approach because it controls the creation, maintenance, and use of the database of an organization and its users. The three major functions of a database management system are first to create new database and database application. Second to maintain the quality of the data in an organized database. And last to use the database of an organization to provide the information that its end users need. An example of a database management approach in a banking information system.

Among them are a work list for manuscript record input and updating forms for relevant directories, retrieval query lists, a selected information display, screen forms for imaging specific document characteristics, an interface facilitating index file building and viewing forms to display information for different user categories, interface for occasional printing by user request.
Highlight the differences between data and information.
The difference between data and information. Data usually is a form of attachment figures are relative. From a data will be processed into a information important for the owners. Usually treatment of an information to be able to give us an information in written and oral form.
Information may be derived from which only. We can see from the difference source of information available. But we should be able to see how a data that has been processed into an information would be helpful to be able making an important decision.
We can try looking from the side of the data can be processed as a valid information. This information will later be able to be one of the key components of the side of a system. We can see from the side of various systems (SIM) and Decision Support System (DSS), a system based on knowledge (knowledge-based system).
From some of the system will be able to form a network of information system using a computer or commonly called the CBIS (Computer Based Information System). From an information system is then we will get to see some professional employees will be needed in this area, namely as programmers, database managers, network specialists and system analysts. We can see how the service information will be helpful to be able to describe the sight of a computer based information system.
We can also see from the side of an understanding of the information that is the result of a processing model, formation, organization and change of a date. While a data usually can be as photos, figures language, symbols and even voice.
Data usually is something that is still raw in nature and require a further treatment. With a view from the side of the technological development that also looks increasingly to develop and we can also make a side view of the importance of accurate data and information. If we are certain operators need accurate information, and trusted to be able to take a decision quickly and accurately.
Make appropriate use of diagrams to illustrate the underlying concepts/components of database management system and information retrieval system.
