Contract Model: Contracts are the staple for any business. Service Level Agreements (SLA), End User License Agreement, and Pricing Agreements are just the beginning of the types of contracts people and companies will enter into to do business. This model provides the understanding of participants of the contract and the beneficiaries of the contract. These two concepts are important as companies can be owned by a parent company in which signs a contract with you that benefits all the subsidiary companies it owns by may not have participated in signing the contract. The model depends on the Party & Account Model.
