The link to access the reading “Steele, J. and Iliinsky, N. 2010. Beautiful Visualization. O’Reilly Media, Inc. Chapter 1 (On Beauty)” is no longer active. It seems that our library no longer has access to some books. Please use chapter 2 (Good Graphics?) from the Data Visualization Handbook as an alternate (click here)

Answers these questions about database basics.
1. What is referential integrity?
2. Should foreign key in a table have only unique values?
3. When is normalization not preferred?
-
Referential Integrity: ensures that the relationship between two table remains synchronized, we cannot add values to the table containing foreign key unless there is a corresponding value in the linked table.
Should foreign key in a table have only unique values? Though it is preferred to have unique values in the foreign key as it becomes easy to map to the table it is linked to, in many to many relationships it is evident that foreign key does not only have unique values.
When is Normalization not preferred? When the databases we are dealing with are highly complex and have too many tables and the queries have too many joins then it not preferred to Normalize and also when the time is limited and when you want an application to be ready quickly, normalization is not preferred. -
– Referential integrity ensures stable relationships between tables by maintaining consistency in values across linked tables.
– Foreign keys need not be unique (specifically in many-to-many relationships), although mapping can be made easier if unique values can be maintained.
– The level of complexity is the primary factor when evaluating whether normalization is preferred. Increasing complexity increases the time required for normalization. Be sure to weigh the additional investment to normalize the data against the value that data will provide if normalized.
