Introduction to Related Data Management
Midterm Exam
1. Since database data items are stored in compatible formats and logical
connections among them are also stored we describe database data as data
dictionary.
2. Analyzing data stored in a data warehouse to find trends is called Data Analysis
3. Faster development of new applications is often possible in a database
environment because tables in Database are logically related.
4. A project management tool that shows tasks, resources, task dependencies, and
timelines for a project is a(n) PERT
5. The phase in which the conceptual model is mapped to the DBMS is the
development of the Database design phase
6. The organization for which the database is designed is referred to as
Computerized system.
7. The two parts of a data sublanguage are DDL and DML
8. In a business, if a department can have many workers, but each worker belongs
to only one department, the cardinality of the department-to-worker relationship is
One to many
9. The basic objects in the E-R model include all of the following EXCEPT table
10. If every member of an entity set must participate in a relationship, the
participation is described as many to one
11. A dashed oval is used to indicate which kind of attribute? Derived attribute
12. Of the following types of keys, the one that does not appear in the Entity-
Relational model is a Foreign key
