13. APPLICATION OF UML LANGUAGE TO DESIGN LAND PRICE INFORMATION SYSTEM IN DAN PHUONG DISTRICT, HANOI CITY

Tóm tắt

Land price is always an issue of concern to society because of its importance in all aspects of life. Currently, the construction of land price information systems is increasingly being developed. Dan Phuong district is a suburban district of Hanoi with a relatively fast development rate. The district still needs to build a land price information system. To make a highly applicable land price information system, designing and modeling the system is extremely important. Currently, there are many applications to create and model databases. For example, the UML language is a popular application that helps users visually identify architecture, design and deploy systems information as quickly as possible. UML is to provide the development community with a popular and stable design language that can be used to develop and build computer applications. UML provides a unified standard modeling notation that information technology professionals have wanted for many years. IT professionals can now read and disseminate system structures and design plans using UML. UML has become a standard modeling language because of its programming language independence. UML is used to design software and information systems in the form of common UML diagrams: use case diagrams, class diagrams, sequence diagrams, state diagrams, activity diagrams, component diagrams, and deployment diagrams. The research used case diagrams to design the land price information system functions and class diagrams to design the land price database. Therefore, we use UML language to create a land price information system and land price database for Dan Phuong district, Hanoi city.
