Concept explainers

Normalization

Normalization is the process of eliminating redundancy in a database by organizing the data into several smaller tables. The large tables are normalized (converted) into smaller tables by using normalization rules, so that a database administrator can easily handle them. It also eliminates insertion, deletion, and update anomalies.

Question

Think about the foreign-key constraint on the instructor's department name property.
Please provide examples of additions and deletions that could go against the
foreign-key restriction.

The Driver Relationship team realized that maintaining driver IDs is difficult and requested an automatic way of incrementing the value when a new driver is added. You need to make the changes on the table to automatically increment the Driver ID. After the change, you need to insert the following driver: First Name: Nursin Last Name: Yilmaz Driving License ID: 4141447 Start Date: 2019-12-28 Driving License Checked: True Rating: 4.0
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.)
