PT2520 Clarence Gross 2/9/12 Homework A scalar function operates on one row at a time. True And aggregate function works on multiple rows a time. True Whenever you have an aggregate function in a query criteria, you must use the HAVING keyword.

True An INNER JOIN returns all the records in the joined tables. False There is no error of the following SQL statement: SELECT CustomerCity, Count (CustomerKey) FROM Customer False There is no error of the following SQL statement: SELECT CustomerCity, Count (CustomerKey) FROM Customer GROUP BY CustomerCity WHERE Count(CustomerCity) > 20 True

Jamel Travis 10/27/2012 Homework Unit 5 Choosing a database management system requires a great deal of analysis. True When choosing a database management system, you should consider system compatibility and hardware requirements. True Only insert and update statements are part of a database transaction. False Physical design is a column specification that determines what kind of data can be stored in it. True A data type is a column specification that determines what kind of data can be stored in it. True Int, decimal and money are character numeric types. True Char and NChr are variable-length character types. True Varchar and NVarchar are based on the Unicode character types. False NChar and NVchar are based on the Unicode character set. True

PT2520 UNIT 4 Clarence Gross 2/2/13 Normalization is the process of removing anomalies from database design. True Not being able to insert data because other data is required is an example of an insertion anomaly. True An insertion anomaly occurs when you enter data inaccurately. False An update anomaly occurs when you have to update the same data in multiple places. True A deletion anomaly occurs when you are unable to delete data in a primary key table because a foreign key table contains records related to that data. False Normal forms are sets of rules designed to remove anomalies and redundancy from database design. False The First Normal Forms removes all repeating groups and arrays. True

PT2520 Clarence Gross 1/19/12 Unit 3 The logical design is independent of any database management system. True The physical design is the logical design adapted to the constraints and features of the database management system. True You should always try to create cross relationships between parent and tables. False Naming conventions help support clarity and consistency in database design. True One to one relationships between entities are valid but rare. True Crow?s feet notation conveys more information about cardinality than arrow notation. True In a one-to-many relationship, each row on in the primary key table can be related to any number of rows in the foreign key or child table. True

False A delimited file is one in which the data is separated by a character such as a comma. True All fixed length files are of the same length. True In relational database, logic design is kept separate from physical design. True A hierarchical database is designed with a tree-like structure that resembles a file system. True Codd defined the core principles of a relational database in 1970 True Data redundancy improves the integrity of a database. False In a diagram, crows feet notation conveys more information about the relationships. True
