The main goal of these thesis is : to carry out all organization process that must be computerized. There are some processes which man cannot carry out withuot special software. The main critical proces is financial control of contracts. Contract begins with signing between our handing organization and customers. Each contract consists of terms and good‘s that must be delivered at time. The name of thesis „long term... „ says that contract conditions are exercised in parts. Goods are been delivered in parts and payment is been getting in parts too. So there are many contracts, and the man is unable to control all its himself. So our software must do financial contract control : to mark parts of good of each contract, allow to see every condition of contracts, and allow to solve the problem of goods identification (BAR codes), because our organization is an agent in trading range. We made our software, theretofore did analysis of excisting software, software that can be partially useful for us and can be upgraded using our functional requirements. We used to modificate typical agreement data model by Len Silverston and use it to transform to DB schema (realationships). Our software (projecting and coding) is made using these tools : Rational Rose, MS Visio, Borland Delphi, MS Access and MS SQL Server.
