An alias is especially useful when a table must be joined to itself in a(n) ___________________ query. - recursive The ___________ condition is generally composed of an equality comparison between the foreign key and the primary key of related tables. - join A database language enables the user to create database and table structures to perform basic data management chores. - TRUE ______________________ is the process the DBMS uses to verify that only registered users access the database....

AREA - In DB2, a named section of permanent storage space that is reserved to store the database. associative entity - See composite entity. bridge entity - See composite entity. candidate key - A minimal superkey; that is, a key that does not contain a subset of attributes that is itself a superkey. See key. closure - A property of relational operators that permits the use of relational algebra operators on existing tables (relations) to produce new relations. composite entity - An enti...

binary relationship -An ER term for an association (relationship) between two entities. For example, PROFESSOR teaches CLASS. cardinality -An attribute that can be further subdivided to yield additional attributes. For example, a phone number such as may be divided into an area code (615), an exchange number (898), and a four-digit code (2368). Compare to simple attribute. composite identifier -In ER modeling, a key composed of more than one attribute. derived attribute -An attribute that...

domain - In data modeling, the construct used to organize and describe an attribute's set of possible values superkey - An attribute or attributes that uniquely identify each entity in a table. Any composite key with this is also this. candidate key - A minimal superkey; that is, a key that does not contain a subset of attributes that is itself a superkey entity integrity - The property of a relational table that guarantees each entity has a unique value in a primary key and that the key...

Unary relationships are common in manufacturing industries. - TRUE _________________ not only helps database designers to stay on track during the design process, it also enables them to pick up the design thread when the time comes to modify the design. - Documentation Ideally, an entity identifier is composed of _____ attribute(s). - one The first step in building an entity-relationship diagram (ERD) is ___________________________________________________________. - creating a detailed n...
