In software, Consistency may refer to many things - Code Consistency, Data Consistency, User Interface Consistency, etc. In this article, I am focusing on Data Consistency. Simply put, Data Consistency ensures that data remains accurate and reliable across different parts of a system. More formally, Data Consistency is one of the Database Transaction properties (ACID^(1)) defined as:

Consistency (or correctness) ensures that a transaction can only bring the database from one consistent state to another, preserving database invariants.
