The DBA denormalized certain data in the TAL Distributors database to improve performance, and one of the resultant tables looks like this: Customer table is not in third normal form due to the following field(s): CustomerNum, CustomerName, Street, City, State, PostalCode, Balance, CreditLimit, RepNum, RepName. Specifically, what does the normal form of the denormalized table look like here?
One of the TAL Distributors database's denormalized tables is as follows: The Customer table is no longer in third normal form due to which column or fields (CustomerNum, CustomerName, Street, City, State, PostalCode, Balance, CreditLimit, RepNum, RepName)? In this example, what is the denormalized table's normal form?
In anticipation of a change to the database, you are asked to provide a list of all products that have 'Man-Made' or 'Man Made' in the the composition text. (HInt: It is easiest to use LIKE in this instance.) In addition, you are requested to replace either 'Man-Made' or 'Man Made' with the word 'Synthetic'. Only include ProductIDs between 1050 and 1060. Show the following in your answer: ProductID, ProductName, Composition, and the modified composition field as 'NewComposition'. (HINT: This problem is a little tricky because you need to replace both 'Man-Made' and 'Man Made'. The way to do this is to use a replace within a replace.)
A select procedure in a relational database can shrink a table's size by deleting columns that don't fit a certain set of requirements.Is it good or bad?

Let's pretend the Student table in a university database is indexed by StudentID (the primary key), Major, Age, Marital Status, and HomeZipCode (all secondary keys). Assume the school needed a list of students from the 45462 zip code who are either over the age of 25, married, and majoring in MIS or computer science OR who are above the age of 25 and majoring in computer engineering and are single. How can indexes be used to restrict access to records that exactly match these parameters?
The Car Maintenance team also wants to store the actual maintenance operations in the database. The team wants to start with a table to store CAR_ID (CHAR(5)), MAINTENANCE_TYPE_ID (CHAR(5)) and MAINTENANCE_DUE (DATE) date for the operation. Create a new table named MAINTENANCES. The PRIMARY_KEY should be the combination of the three fields. The CAR_ID and MAINTENACNE_TYPE_ID should be foreign keys to their original tables. Cascade update and cascade delete the foreign keys.

Not all versions of this database include referential integrity constraints for all foreign keys. Use whatever commands are available for the RDBMS you are using, investigate if any referential integrity constraints are missing. Write any missing constraints and, if possible, add them to the associated table definitions.
