Introduction
Word Tour Company is a company that offer facility of booking and paying tours online. Due
to advancement of technology, it has raised a need for the company to automate its service in
order to get more clients all over the world. In order to achieve this, the company need to
develop a system where customers can search for the available tour packages and the tour
guide associated with that tour. This system checks whether the user exists or new. If new,
the customer enters personal and tour details for reservation. The system provides customer
with unique id and password. If the customer exists, the system asks the customer to login.
The system verifies the login credentials and if correct the system allows the customer to
continue with the booking process. Registered customers can update their personal details or
even cancel the tour package. Customer makes payments after confirming their touring
packages. Also customers can view the details of their touring details including the tour guide
who will be associated with the tour. Administrator can change, delete or modify the tour
scheme and the associated tour guide.
Methodology
Development life cycle is a term used to describe the process of planning, design and
implementation, testing, deployment and maintenance of an information system. The SDLC
aim at developing a high quality software of hardware. The SDLC involves a number of
clearly defined and distinct phases which are; (Kendall et al, 1992)
i. Planning.
This is the phase where by the whole procedure of developing the system is done. A
preliminary analysis is done and an alternative solution is proposed. The cost of the
whole activity is estimated.
ii. Designing.
In this phase the desired and required features of the system is visualised. This may
include screen layout, data flow diagrams, pseudo codes and how various components
are connected.
iii. Development and implementation
This is the phase where the actual system is created. The engineers can develop units
separately for easier development and specialization. This is the phase where the real
codes are written.
iv. Integration and testing

Various units are verified if they meet their requirements. Then these units are
integrated and tested as a system. Here the client data is used to check if the system
meets the desires of the client.
v. Documentation
After the system is verified that it meets the client specification, a document is
prepared that contains the usage and features of the system.
vi. Deployment and maintenance
This is the last phase of the SDLC. The verified system is put to work. Various users
of the system are trained on how to operate the system. Maintenance is the process of
correcting errors which were not detected in the other phases, improving the system
and updating the features of the system.
Types of approach in SDLC
The following are the two types of approaches in SDLC;
Predictive approach
Advantages
i. Easy to understand
ii. Easy to estimate the budget
iii. Easy to manage
Disadvantages
i. No prototype is produced until the end.
ii. Not suitable for complex system.
Adaptive approach
Advantages
i. There is high interaction between the developers and client which makes it easier to
understand the client requirement and to correct errors.
ii. There is transparency in the development process
iii. High quality system is realised
Disadvantages
