The customer
The customer data contains the name and address of the company or client. It lets the Quotation and Bill tables perform a relation of this data and use the data. Being the master data, adding to and deleting from the user interface is not available at this time. However, as you develop the application, you eventually should be able to edit this data.
The following screenshot shows the input fields for registering a customer. The sections under the Name column are the fields that need to be filled in for each customer. The Type column refers to the type of data to be entered, such as words, numbers, and dates. The Key column allows data to be referenced between different tables.
