INITIAL IDEA 2

Database Design 


    A database is an organized collection of structure information, or data that are electronically stored in the computer system which is controlled by the DBMS (database management system). Database management system are software systems used to store, retrieve, and run queries on data.
All database system stores data using file, records and fields (Graham, Brian, and David. (2010)  information and communication technology. 2nd ed. London. Hodder education):
  • FIELD: A file is a single item of data, such as forename or date of birth which has a field name that is used to identify it within a database.
  • RECORDS: A record is a collection of fields, for example all the information about one person or item
  • FILE: A file is an organised  collection records, usually where all the records are organised so that they can be stored together.
In addition, according to Graham, Brian, and David.  information and communication technology. 2nd ed. London. page 268, database consist of two main types: Flat-file database and Relational database.
A flat-file database sorts its data in a table which is organised in columns and rows. Each column in the table contains a field, which has been given a field name, and each cell in the column has the same.
A relational database are designs so that the same data is not duplicated in a table. Each table within a relational database will have a field key.

What are the advantages and disadvantages of database designs?  database designs are known to make the storage of data less complex and easy to access. Data protection is very essential, only authorized user should be able to access various type of data, database design ensures the safety of data from unauthorized user under any circumstance, they also ensure the backup and recovery of data (Admin, 2022).
The disadvantages of database design include the financial cost required to support hardware and equipment to operate the database program, they also require frequent hardware update which can be very costly to acquire and need new educational guide to handle functionality properly (Admin, 2022).

    "field and File" which are you referring to?. Clear that. (GRAHAM, B., BRIAN, S., and DAVID, W. (2010) should be in Name format and not capital letters all through and it should be (Graham, Brain, and David 2010)
    what is igcse? again your reference font, entire work justification.

DIAGRAM 1. SOFTWARE DEVELOPMENT LIFECYCLE (SDLC)

  Software development lifecycle (SDLC) are the steps recurred in other to carry out and improve the process of developing a software application.  PLANNING:   This include the calculations of material cost and labor to create a timetable with a goal allowing the application outline and boundaries that are needed to keep the project from expanding beyond scope DEFINE REQUIREMENT:   This is used to define what the application is meant to do including resources needed to be identified and built into the project in order to achieve the goal . DESIGN AND PROTOTYPING:   This are the designing steps that instructs the application on how it will work. Some of these steps include Programming, Security, Communications, Architecture and Platforms. After the design has been defined, a prototype of an early version of the software can be created to demonstrate a basic idea of how the application will work. SOFTWARE DEVELOPMENT:   This is where a program ia written out by a single developer or a la
