SQLite database
Without the help of a 3rd party user interface (UI) program, SQLite runs mainly using command prompt commands. The team feels that this would be non-intuitive for the user and hence not user friendly. Therefore, the team has decided to use SQLiteStudio as the main UI. SQLiteStudio allows users to perform create, read, update, delete (CRUD) functions using either SQL or the UI. It also allows us to import and export databases or tables in .csv format. Most of the functions are available in the form of a UI, thus prior knowledge of SQL required in order to configure the database is kept to a minimal.
SQLite Entity Diagram
When creating the tables and its columns, we took into consideration the historical records so as to keep as close to the as-is situation as possible. We are still in the midst of discussing certain naming conventions with our client.

Functions
1. Add new purchases – when there is a new purchase, the counter staff will use this function to add a new customer purchase record into the database. If the customer is a new member, the new member will be automatically added into the ‘Member’ table.
2. Mark attendance – before a class starts, the counter staff will use this function to add a new ‘DailyClass’ object. Following which, he/she will enter the names of the members that attended this class. Using the ‘PackagePurchase’ table, the function will search for the latest package purchase by the member and fill the ‘Attendance’ table.
3. Update – this function allows the counter staff to amend any errors that he/she has made in the previous entries.
