Q1. please create a Level-0 DFD for Training, Inc.

Training, Inc., conducts training seminars in major US cities. For each seminar, the logistics department must make arrangements for the meeting facilities, the training consultants travel, and the shipment of any seminar materials. For each scheduled seminar, the bookings department notifies the logistics coordinator of the type of seminar, the dates, the city location, and the name of the consultant who will conduct the training. To arrange for meeting facilities, the logistics coordinator gathers information on possible meeting sites in the scheduled city. The meeting site location decision is made based on date availability, cost, and type of meeting space available. Once the site decision is made, the coordinator speaks with the sales manager of the meeting facility to reserve the meeting room(s) and any necessary equipment. The coordinator estimates the number and size of meeting rooms and the equipment needed for each seminar from the information kept in a logistics database on each type of seminar offered and the number of anticipated registrants for a particular booking. The logistics coordinator obtains the initial price from the sales manager, and occasionally makes a counteroffer. In the case of a counteroffer, the sales manager usually makes an additional counteroffer. When the price is agreed upon, the sales manager creates a contract specifying the negotiated arrangements and sends two copies of it to the logistics coordinator. The coordinator reviews the contract and approves it if no changes are needed. One copy of the final contract is filed and the other copy is sent back to the sales manager. If the logistics coordinator asks for changes, the sales manager adjusts the contract and returns it for approval. The coordinator must also contact the training consultant to make travel arrangements. First, the coordinator reviews the consultants travel information in the logistics database and researches flight schedules. Then the consultant is contacted to discuss possible travel arrangements; subsequently, the coordinator books a flight for the consultant with a travel agent. Once the consultants travel arrangements have been completed, a written confirmation and itinerary are sent to the consultant. Two weeks before the date of the seminar, the coordinator determines what, if any, seminar material (e.g. training guides, pamphlets, etc.) need to be sent to the meeting facility. Each type of seminar has a specific set of materials assigned to it. A request for materials is sent to the material-handling department where materials are gathered, boxed, and sent to the meeting address listed on the request. Once the requested materials have been shipped, a notification is sent to the logistics coordinator.
