2. Database conventionization is the process of organizing the fields and tables of a relational infobase to background redundancy and dependency. common repointization usually involves dividing large tables into smaller (and less(prenominal) redundant) tables and defining relationships between them. The objective is to isolate data so that additions, deletions, and modifications of a field can be made in just one table and then propagated through with(predicate) the break of the database via the defined relationships.
3. First convening found (1NF)
First normal form (1NF) sets the very basic rules for an organized database:
* Eliminate duplicative tugboats from the like table.
* Create separate tables for each group of related data and identify each row with a unique column or set of columns (the primary key).

Second Normal Form (2NF)
Second normal form (2NF) further addresses the pattern of removing duplicative data:
* Meet all the fates of the first normal form.
* look at subsets of data that apply to multiple rows of a table and place them in separate tables.
* Create relationships between these new tables and their predecessors through the use of foreign keys.

Third Normal Form (3NF)
Third normal form (3NF) goes one large measurement further:
* Meet all the requirements of the second normal form.
* pull back columns that are not dependent upon the primary key.

Boyce-Codd Normal Form (BCNF or 3.5NF)
The Boyce-Codd Normal Form, also referred to as the third gear and half (3.5) normal form, adds one more requirement:
* Meet all the requirements of the third normal form.
* Every clincher must be a candidate key.
