What is FNM?

First Normal Form, commonly abbreviated as 1NF or FNM in certain academic notes and textbooks, is a foundational concept in database normalization used in the field of relational database management systems. It refers to the first level of normalization introduced by Edgar F. Codd in his 1970 relational model, and it requires that every column in a table holds atomic values, meaning each cell contains a single, indivisible piece of data with no repeating groups or arrays. FNM plays an important role in the Indian IT and software education ecosystem, where students of computer science, information technology, and data engineering learn it as part of their undergraduate and postgraduate curricula. It is widely used in database design interviews, software development roles, and data analytics positions across tech companies in Bengaluru, Hyderabad, Pune, and other IT hubs. The concept regularly appears in competitive examinations such as GATE Computer Science, UGC NET Computer Science, and various state-level public service commission technical tests, making it a high-priority topic for aspirants preparing for these exams.
