“Supporting a travel agency, TORS maintains tour information and provides reservation facilities for the people who wish to travel on tours via the Internet. The system allows users to view information about the tours available and make a reservation on a tour without asking the employees at the agency. Using the system, a user can cancel an existing reservation that the user made. The system also allows the user to send feedbacks by e-mail to the agency and stores the feedback in the database. Finally, the system allows the employees of the agency to manage customer information and tours such as adding, deleting, and updating information on customers and tours. For security purposes, the employees are required to provide login credentials (ID and password) to access the system.”   1.

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.
