IT Magazine A magazine called “IT in the Valley” is published every month. An information system is needed to help deal with the editing of the magazine. It should also help with the payments to the contributors of stories and photographs and the receipt of payment from the advertisers.

The enterprise consists of four main departments: A Marketing Department, an Editing Department, a Processing Centre and an Accounts Department. The information system will collect adverts, stories and photographs and publish magazine issues. It will also pay the journalists and photographers whose stories and photographs are published. The Marketing Department receives advertising details from advertisers. Details of these adverts are recorded. The system should record who is to pay for the advertisement when it should appear and how large the advert should be. There may be other considerations such as where in the 5 magazine it should appear. The Marketing Department passes the advertisement to the editor. An advertiser may place several different adverts in the same issue of the magazine.

The Editor checks and edits the adverts and sends them to the processing centre, where all the data concerning the content of the advertisement are stored this would normally consist of text and graphics. In addition to the advertisements the magazine consists of a mixture of stories and adverts. A freelancing journalist submits stories to the editor. Sometimes a successful journalist has more than one story in the same issue. Details of the journalists are kept for reference purposes. When a story is published the journalist is automatically paid an agreed amount. A similar situation exists for photographers. Photographers and journalists may be regular contributors or occasional contributors. Details of the stories and photographs must be stored. Complete issues of the magazine are also stored so old stories may be researched in the future. Any stories or photographs that have been submitted and remain unused after six months are archived.

The editor may match one or more photographs with a story to illustrate it. The editor chooses all the stories adverts and photographs and puts them together to form the magazine issue. Copies of completed issues of the magazine are sent to advertisers. At the end of each month the Accounts Department send out payment to each of the journalists and photographers who have had a story published in the last issue of the magazine. The fee will have previously been agreed between the Editor and the journalist or photographer. The Accounts Department will also invoice the advertisers for adverts that have been published. If no payment is received within two months they will begin to bring legal proceedings against their debtors
