Why is atomicity important in database design?
Atomicity is important for applications wanting to update two related databases (for example, a primary database and secondary index) in a single logical action. Any number of operations on any number of databases can be included in a single transaction to ensure the atomicity of the operations.
What is atomicity in file system?

What is atomicity give example?
Atomicity is defined as the total number of atoms present in a molecule. For example, each molecule of oxygen (O2) is composed of two oxygen atoms. So atomicity of oxygen is 2. Some authors also use the term to refer to the maximum number of valencies observed for an element.
What is atomicity in DBMS?

What is ACID property in database?

What is semantic in database?
The second kind of semantic data models are usually meant to create semantic databases. The ability to include meaning in semantic databases facilitates building distributed databases that enable applications to interpret the meaning from the content.
