From Wikipedia, the free encyclopedia. Database normalization, or simply normalization, is the process of organizing the columns (attributes) and tables (relations) of a relational database to reduce data redundancy and improve data integrity.
1 Snapshot replication: Data on one server is simply copied to another server, or to another database on the same server. 2  Merging replication: Data from two or more databases is combined into a single database.he result is a distributed database in which users can access data relevant to their tasks without interfering with the work of others. The implementation of database replication for the purpose of eliminating data ambiguity or inconsistency among users is known as normalization.
