program. Today, most of the systems are developed in a web-based environment, or at
least intranet.
Database building and testing
We can say that a database is compulsory for any system. As mentioned earlier,
database is a place where we kept all the data. So, this task must be leading other
programming activities because database is shared by the computer program. If the
system develop require a new or enhanced database, this task is required.
Install and test new software
Not all, but most of the system development requires the organization to purchase or
lease a new software package. If required, this software should be installed and tested
once the previous task is completed.
Write and test new programs
This is the major task in coding activity. Once we have completed all the previous tasks;
we can start to develop the system. Today, most of the organizations prefer to use
prototyping approach when developing the system.
12.2.1 Exercises
Answer TRUE or for FALSE for each of the questions below.
1. Coding is the process whereby the physical specifications created in the previous phases
are turned into working computer codes by the programmer team. TRUE
2. There are several sub activities involved during coding and all this activities are compulsory.
FALSE
3. Most of the system developed is around the existing network, so, no need to build and test a
network. TRUE
4. Database installed should be tested. TRUE
5. Most of the organizations are prefer to use prototyping when develop a system. TRUE
12.3 SYSTEM TESTING
After coding, a programmer must conduct a test. Each program will be tested in order to make
sure it functions correctly. Later, programs are tested in groups, followed by testing with the
entire system. The first step in testing is to compile the program to detect any syntax errors. If
