Methodology Definition
This chapter involves background information, definition of water fall model its
various stages and the need for water fall model. The chapter covers data collection
methods which will be used during the study the methods are interview, observation
and sampling selection, this has been elaborated by Chodorow (2013), when he talks
about developing systems using nodejs. After data collection the chapter focuses on
analysis of data, initial data will be analyzed using statistical methods such as
inferential and descriptive techniques. The methods used to carry out research such as
the assumptions in theories and philosophy is referred to as the research methodology.
The methodology used according to Satheesh, D'mello and Krol ( 2015) developing
an Ecommerce Project is best done using the Incremental model where in this model,
it allows for the modeling independent modules of the system separately up to
completion. I preferred to use this as it allowed me the chance of working with the
different modules independently. The modules are shown below:
