Till this point, you have finalized the contract. Let's save the contract information in the database. We can achieve it by communicating with either an external service, which performs the service of interacting with the desired database and performs an insert operation into it. This external service could be a BPEL Service, Mediator service, Adapter Service, or another BPM Process itself. Let's take the case of invoking an Adapter Service (Database Adapter) to perform the insert operation. As a Process Analyst, you will model the service call in the process. However you will implement it in Implementation phase.
