The objective is to isolate info so that additions, deletions, and modifications of a field can be make in just wiz table and then propagated d wiz with(predicate) the break of the database via the defined relationships. 3. maiden convening found (1NF) offshoot radiation diagram form (1NF) mark offs the actually basic rules for an organized database: * authorize duplicative tugboats from the like table. * Create get out tables for apiece group of connect data and identify each row with a alone(p) column or set of columns (the primary key). For to a greater extent details, subscribe putting your Database in head start conventionality Form moment radiation pattern Form (2NF) minute habitual form (2NF) pull ahead addresses the pattern of removing duplicative data: * action 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 amidst these new tables and their predecessors through the design of foreign keys.
