Databases and Web Access
Informally, a database (DB) is an organized collection of data, or in other words, a collection of records or pieces of knowledge. Common examples of a DB would be a telephone book, mailing list, and a recipe book. A database management system (DBMS) is software to create a DB and to store and query this DB. In other words, a DBMS is a collection of software modules that manage data storage, query processing, and data recovery (Silberschatz, Korth et al. 2010).
