The system development phase is a series of steps used to develop a database program.
These phases describe the processes that system developers carry out in order to develop a database program.
OVERVIEW OF SYSTEM DEVELOPMENT PHASES
Analysis Phase
During the Analysis Phase, system developers will perform problem analysis by finding out the needs of target users.System developers also identify the input, process and output for the new system.
Design Phase
Based on the needs of target users, the system developers will design an Entity Relationship Diagram (ERD). This phase is known as the Design Phase.
Implementation Phase
Implementation Phase is the phase where system developers create database using database software.
Testing Phase
The system will be tested by the target users in the Testing Phase.If there is any error detected, the system developers will fix the error.
Documentation Phase
System developers will produce the documents for the program during the Documentation Phase.
Maintenance Phase
The system developers continue to provide support during the Maintenance Phase. They monitor the system performance and make changes when needed.
EXTENSION : PRACTICES OF DEVELOPING A NEW
INFORMATION SYSTEM
Some practices of developing a new information system:
Work as a group
When you want to develop an information system, you must work as a group. All group members must work together to complete tasks like data entry and analysis.
Involves many people
Involve as many people as possible in your project. This means that you should not only think of people in your group but also friends and teachers who will use your information system.
Willing to accept changes
Create a culture among yourselves to accept changes. For example, each of you should try changing roles throughout your project so that everyone learns each other’s responsibilities.
You must be willing to accept changes when others give comments or recommendations. Share with others
Tell as many people as you can about what your group is doing. This encourages sharing of ideas and learning from one another.
