Is a database that is in third normal form automatically in first and second normal form?

Yes, each normal form builds upon the lower forms, such that a database in form N will also be in form N-1, N-2, etc. A database in fifth normal form, for example, will also be in first through fourth normal forms.

What is database accuracy?
Disclosed which assists in finding errors in a reference database by making comparisons to an interchange database. The reference and interchange databases containing first and second groups of related data strings. The data strings from the first groups are compared to find matching datmatch. When no matching conditions are detected, an error indication is generated.

What do most database designer prefer 1NF 2NF or 3NF?
First normal form (1NF) sets the very basic rules for an organized database: * Eliminate duplicative columns from the same 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) further addresses the concept of removing duplicative data: * Meet all the requirements of the first normal form. * Remove 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) goes one large step further: * Meet all the requirements of the second normal form. * Remove columns that are not dependent upon the primary key. Finally, fourth normal form (4NF) has one additional requirement: * Meet all the requirements of the third normal form. * A relation is in 4NF if it has no multi-valued dependencies. Remember, these normalization guidelines are cumulative. For a database to be in 2NF, it must first fulfill all the criteria of a 1NF database.
1st to 5th normalization form in database?
the inventor of the relational model, introduced the concept of normalization and what we now know as the First Normal Form (1NF) in 1970.[1] Codd went on to define the Second Normal Form (2NF) and Third Normal Form (3NF) in 1971,[2] and Codd and Raymond F. Boyce defined the Boyce-Codd Normal Form (BCNF) in 1974.[3] Informally, a relational database table is often described as "normalized" if it is in the Third Normal Form.[4] Most 3NF tables are free of insertion, update, and deletion anomalies.
