What are the objectives of the Database Overview 9.1 unit?
The objectives of the Database Overview 9.1 unit are to understand the types of databases, gain insight into SQL and its features, learn about JDBC and ODBC, and gain knowledge on indexing and database clustering.
What is an information system?
An information system is a system that comprises hardware, software, policies, and other components, and is used to process, interpret, and organize useful or meaningful information.
What is the traditional approach to data requirements for applications?
The traditional approach involves deriving data requirements for applications independently, developing applications in an ad-hoc and opportunistic manner, and having application programs that are data dependent.
What are data files developed for in the traditional approach?
In the traditional approach, data files are developed for individual purposes or applications.
