Main concept of SQL Server locking

In this post, we will discuss the SQL Server lock mechanism and how to monitor SQL Server locking with SQL Server standard dynamic management views. Before we start to explain SQL Server lock architecture, let's take a moment to describe what the ACID (Atomicity, Consistency, Isolation, and Durability) database is. The ACID database can be explained as database theory. If a database is called relational database, it has to meet Atomicity, Consistency, Isolation, and Durability requirements. Now, we will explain these requirements briefly. Atomicity: It reflects the principle of indivisibility that we describe as the main feature of the transaction process. A transaction block cannot be left unattended. Half of the remaining transaction block causes data inconsistency. Either the entire transaction is performed or the transaction returns to the beginning. That is, all changes made by the transaction are undone and returned to their previous state. Consistency: There is a rule that sets the substructure of the non-divisibility rule.
