Various integrity rules in a DBMS?

Three basic types of database integrity constraints are:Entity integrity, not allowing multiple rows to have the same identity within a table.Domain integrity, restricting data to predefined data types, e.g.: dates.Referential integrity, requiring the existence of a related row in another table, e.g. a customer for a given customer ID.

What is data redundancy and data integrity?

Data inconsistency exists when different and conflicting versions of the same data appear in different places. Data inconsistency creates unreliable information, because it will be difficult to determine which version of the information is correct. (It's difficult to make correct - and timely - decisions if those decisions are based on conflicting information.) Data inconsistency is likely to occur when there is data redundancy. Data redundancy occurs when the data file/database file contains redundant - unnecessarily duplicated - data. That's why one major goal of good database design is to eliminate data redundancy. In the below link you can find more details. http://opencourseware.kfupm.edu.sa/colleges/cim/acctmis/mis311/files%5CChapter1-Database_Systems_Topic_2_Introducing_Databases.pdf
