Information is made from Data that is numerical which is changed and used to make it seem sense. For an example train timetable, the number of trains and how much it weights.

2. using the data requirements and the business rules provided, develop a conceptual model (ERD), including attribute data types and required field lengths; and

the correct date and a full signature of the person writing the record. It is also

Data is defined as useful raw material which is intended to be useful for both the originator and for the intended receiver. Data consists largely of facts and figures ideal for communicating the intended meaning. This data can be interpreted and can be categorised as follows;

Storing information is essential for many reasons; these include easy access and changing readability for all reading levels, the level of detail you are able to store, the choice to have various copies of the information in case of loss and ease of transfer.

to inform decision making : when changing policies and procedures it is crucial to have records of data to direct the process. For example, a record of accidents can help understand what needs to be done to prevent them, discipline unsafe behaviours or creating safety checklists.

The five major components of an information system are as follows (1) to (5); (1) Hardware, multiple computer systems: microcomputers, minicomputers, and mainframes. (2) Software- computer software falls into two categories; systems software and applications software. Systems software manages the resources of the computer system and simplifies programming. Application Software is a program that directly assists end users in doing their work. Both can be purchased as ready-to-use packages. (3) Networks and communication facilities, includes Internet and intranets. This hardware and software facilitates fast and efficient transmission and reception of text, pictures and

Relational data is when you can put data in a computer one time and it grows

The main purpose of storing any information is for easy retrieval in the future when it is required. It is also part of a company’s business practice. Storing documents have to be done in proper procedure so that it is easier to find. Depending on the type of information, information can be stored in either fireproof cabinets for hard copies or hard disks or other electronic storage devices for soft copies.

* Collect and store data which may be converted into information at some later point in time

Information is data that has been processed so that it has meaning and value to a recipient,

Data Flow Modelling – This is the process of modelling and recording how data flows around a system. A Data Flow Model is made up of connected Data Flow Diagrams (DFD) which are supported by appropriate documentation. DFDs represent the processes and functions within a system (activates that transform data from one form to another), data stores (file storage, external entities (things that send data into a system or receive data from a system) and finally data flows (show the flow of data around the system).

• Entity-relationship modeling is logical representation of the data for an organization or for a business area. The E-R model is expressed in terms of entities in the business environment, the relationship among those entities, and attributes of both entities and their

Databases allow us to easily store and retrieve data in a purely digital format. The strength of this is that large amounts of data can be stored and retrieved with minimal effort on the part of the user. Opposed to manually flipping through files, one can quickly pull up the requested data through a computer program. Many systems that were conventionally paper and file based have been converted to a digital format which are now stored in one or more databases.

The interview session has been done by include an open-ended and closed-ended question which are related to the implemented project. Next, sampling technique is executed by system analyst who does evaluation to the current system or prototype. These processes give feedback in evaluation form that filled after tested the system. Lastly, observation is performed by using questionnaire form. According to Burch (1992), the questionnaire is analyzed and transform into structured form that easy to understand. After all information has been collected, structuring of system requirement takes place. It focused on development process modeling which perform “graphically representing the process, or actions, that capture, manipulate, store, and distribute data between a system and environment” (Hoffer, George, & Valacich, 2012, p. 182). In this step, Data flow diagram (DFD) is structured by system analyst using special tools and techniques to create a decision table. According to Hoffer, George and Valacich (2012), decision table is a “diagram of process logic where the logic is reasonably complicated” (p. 200). This table is useful to help system analyst to make a decision toward the project. Then all information’s gained from this phase are documented in System Analysis Report (SAR) that acts as a guideline or reference to the future system development project (Burch, 1992).
