It has been managing the business activities and data using excel sheets. However, managing their business without a proper database and a front-end application causes many redundancies and inefficiencies in addition to not being able to reach prospective customers. They also envisioned that through their e-commerce site, prospective customers would be able to view the 3-D designs of their boats in addition to being able to buy the spare parts online.

With the aim of expanding the business, the senior management decided to investigate the option of implementing a database system along with hosting its own e-commerce website to sell its product range.
