外文原文 Java Web technology The so-called Java Web technology, is the use of Java technology to solve the Web Internet domain technology integration. The web mainly includes server and client, but it has some limitations. The application of Java in the client side mainly includes Java applets, but the frequency of use is not high. The application of Java in the server side is relatively rich, usually including servlets, JSPS, third-party frameworks and so on. It can be said that Java technology can inject a powerful impetus into the development of the web domain and improve web performance. Information system planning based on information engineering is a source of database development projects. Those who develop new databases Projects are usually undertaken to meet the strategic needs of the organization, such as improving customer support, improving product and inventory management, or carrying out More accurate sales forecasts. However, many database development projects appear more bottom-up, for example Users of information systems need specific information to complete their work, request to start a project, and so on Information systems experts discover that organizations need to improve data management and start new projects. Even in the bottom-up case, It is also necessary to establish an enterprise data model in order to understand whether the existing database can provide the required data; otherwise, New databases, data entities, and attributes should all be added to the current organization's data resources. Each database development project is typically focused on one database, whether it is strategic requirements or operational information requirements On. Some database projects focus solely on defining, designing, and implementing a database as a subsequent information system The basis of hair. In most cases, however, the database and its associated information processing capabilities are treated as one complete piece of information Developed as part of
