Database systems introduction
Database systems can be summarized in 3 sentences:
A database system consists of a database, database management system (DBMS), and users. The database contains organized data, the DBMS manages access to the data and provides utilities for querying and updating it, and users interact with the system for data entry, retrieval, and administration. Over time, database models have evolved from hierarchical and network models to the prevalent relational model to better support data sharing and querying across systems.

database designers, and end users to help them design, administer, and use a database. Then we
gave a brief historical perspective on the evolution of database applications. We pointed out the
recent rapid growth of the amounts and types of data that must be stored in databases, and we
discussed the emergence of new systems for handling \"big data\" applications. Finally, we
discussed the overhead costs of using a DBMS and discussed some situations in which it may not
be advantageous to use one. Define the following terms: data, database, DBMS, database
system, database catalog, program-data independence, user view, DBA, end user, canned
transaction, deductive database system, persistent object, meta-data, and transaction-processing
application. What four main types of actions involve databases? Briefly discuss each. Discuss
the main characteristics of the database approach and how it differs from traditional file systems.
What are the responsibilities of the DBA and the database designers? What are the different
types of database end users? Discuss the main activities of each. Discuss the capabilities that
should be provided by a DBMS. Discuss the differences between database systems and
information retrieval systems. Identify some informal queries and update operations that you
would expect to apply to the database shown in Figure 1.2. What is the difference between
