A relation is said to be in 1NF iff each arttribute of the relation is atomic i.e each column must contain only single value.
basic rules for 1NF
1.eliminate duplicate column from the same table
2.create separate table for a gr. of related data and distinguish each row with a unique column or set of column

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.
Exaplain three types of normalization with example?
normal form 1 normal form 2 normal form 3
What are different normal forms?
There are 4 normal forms in databases. First normal form, second, third and fourth normal forms are there.
What are the different types of form?
First normal form, second normal form, third normal form, fourth normal form, fifth normal form and Boyce Codd normal form. See the related question below.

Explain the first 3 normal forms in dbms?
First Normal Form: Remove the repeating groups in a table Second Normal Form: Remove partial dependencies Third Normal Form: Remove transitive depedencies
How many normal forms are there?
In database design, there are several normal forms, typically including the first three: First Normal Form (1NF), Second Normal Form (2NF), and Third Normal Form (3NF). Beyond these, there are also Boyce-Codd Normal Form (BCNF), Fourth Normal Form (4NF), and Fifth Normal Form (5NF). Each normal form addresses specific types of redundancy and dependency issues to ensure data integrity and efficiency in relational databases. Higher normal forms exist, but the first five are the most commonly referenced.

What is first normal form in DBMS with example?
The first normal form or 1NF is the first and the simplest type of normalization that can be implemented in a database.The main aims of 1NF are to:Eliminate duplicative columns from the same table.Create separate tables for each group of related data and identify each row with a unique column (the primary key).
What is the standard form of 2.5?
Writing a number in standard form simply means to express the number in its 'normal' form. Therefore, your example is written in standard form as: 25
