A more thorough explanation:

Definition: Integration means combining separate things to make them whole or united. In contract law, it refers to the complete expression of an agreement between parties on a particular subject matter. An integration clause in a contract prevents parties from contradicting terms or proving additional ones based on previous agreements.

Example 1: A company wants to integrate its different departments to work together as a single unit. This means that the departments will share information, resources, and work towards a common goal.

Example 2: Two parties enter into a contract to sell a car. The contract includes all the terms and conditions of the sale, such as the price, delivery date, and warranty. The integration clause in the contract prevents either party from adding or changing any terms based on previous discussions or agreements.

These examples illustrate how integration can be applied in different contexts. In the first example, integration refers to the process of bringing together separate entities to work as a unified whole. In the second example, integration refers to the complete expression of an agreement between parties, which prevents any further changes or additions based on previous discussions or agreements.
