Which is the lowest normal form in DBMS?
Correct answer: A. 1NF
- A. 1NF
- B. 2NF
- C. 3NF
- D. BCNF
Explanation
First Normal Form (1NF) is the most basic level of normalization in a relational database. It ensures that every table cell contains a single atomic value (indivisible unit of data), and there are no repeating groups of data within a table. This helps to streamline data organization and avoid redundancy. In essence, 1NF is the foundation for all further normalization levels. You need to achieve 1NF before moving on to higher normal forms like 2NF, 3NF, and BCNF

About Databases
Databases cover tables, records, fields, keys and relationships, together with database management systems and relational database design. The subject includes primary and foreign keys, normalization, SQL commands such as SELECT, INSERT, UPDATE and DELETE, queries, forms and reports, while distinguishing a database from a spreadsheet used for simple tabular data.
