Serializability:

Serializability is a fundamental concept in database management systems that ensures transactions execute in a manner consistent with some serial order, even though they may be executed concurrently. In simpler terms, it guarantees that the outcome of executing multiple transactions concurrently is equivalent to some serial execution of those transactions.

Let's consider an example to illustrate serializability:

Suppose we have two transactions T1 and T2:

```
T1: Read(A)
A = A + 50
