Intermediate SQL Concepts

A query is a request for data or information from one or more database tables. This information could be presented in the form of pictorials, graphs, or complicated findings which helps in easy interpretation. Structured Query Language (SQL) is the most widely used programming language for retrieving and organizing data from relational databases. Collection of tables with rows and columns is referred to as a database. SQL is the language of databases. It makes it easier to extract specific data from databases, which can then be used for analysis.

The Save Transaction button depicted in the screen attached is used to save relevant data to the sales table and the salesdetails tables from the depicted schema. When this button is clicked it calls the saveTransaction() function that is within the PosDAO class, it passes to this function an ArrayList of salesdetails object, this list contains the data entered into the jTable which is the products and qty being sold.Write the saveTransaction function. You are to loop through the items and get the total sales, next you are to insert the current date and the total sales into the sales table. Reminder that the sales table SalesNumber field is set to AUTO-INCREMENT, hence the reason for only entering the total sales and current date in sales table.
