• A                  on an attribute of a relation is a data structure that allows the database system to find those tuples in the relation that have a specified value for that attribute efficiently, without scanning through all the tuples of the relation.
• Suppose now that R(A,B:) and S(A,B:) are two relations with r and s tuples, respectively (again, not necessarily distinct). If m is the number of (not necessarily distinct) tuples in the result of the SQL query: R intersect S; Then which of the following is the most restrictive, correct condition on the value of m?
• Which one of the following provides the ability to query information from the database and to insert tuples into, delete tuples from, and modify tuples in the database?
• The           operation allows the combining of two relations by merging pairs of tuples, one from each relation, into a single tuple.
• In a                            operations do not wait for requests to produce tuples, but instead generate the tuples eagerly.
• Bitmaps can be combined with regular B+- tree indices for relations where a few attribute values are extremely common, and other values also occur, but much less frequently.
• The attribute name could be structured as an attribute consisting of first name, middle initial, and last name. This type of attribute is called
• Every time attribute A appears, it is matched with the same value of attribute B, but not the same value of attribute C. Therefore, it is true that:
• The attribute name could be structured as an attribute consisting of first name, middle initial, and last name. This type of attribute is called
• Which of the syntax is correct for insert statement? i) insert into <table_name> values <list of values> ii) insert into <table_name> (column list) values <list of values>
