Development and Implementation of Enterprise Management System Based on J2EE

In the current enterprise management system, the coupling relationship between enterprise management and operation and maintenance database is not considered, which leads to many system vulnerabilities, slow running speed, and long response time. An enterprise management system based on edge computing architecture is designed. According to the characteristics of mobile edge computing, we design the architecture of the edge computing platform, integrate the MEC virtualization infrastructure layer, MEC platform layer, and MEC application layer, construct the edge computing model, reflect the coupling relationship between enterprise management and operation and maintenance database, calculate the delay vector of the enterprise management server, and complete the parameter calculation of enterprise management and operation and maintenance system. This paper analyzes the feasibility, objectives, and users and functional requirements of the enterprise management system, designs the functional structure of the system, realizes the design of the public module, function menu module, and login module, adopts the SQL database management system, and designs the database and data table, so as to realize the design of the enterprise management system based on edge computing architecture. Experimental results show that the proposed method has fewer system vulnerabilities and can effectively speed up the system operation speed and shorten the system response time.

In accordance with the instructions of the national industry and commerce department, an online electronic information platform for enterprise operation and management shall be established. Enterprise management is a collection of enterprise name verification, private operation, domestic capital management, foreign capital management, trademark management, advertising supervision, case handling, enterprise early warning, credit file, case management, contract management, daily management, and fee management.On this basis, the specific design of several main business units, such as enterprise registration, daily management, and case management, is proposed.

In the article on the basis of semantic analysis (the terms "costs", "management", "cost management", "enterprise", "cost management in the enterprise", "method") and determining the place of cost management methods in the cost management system at the enterprise such management methods. The chronology of development of methods of management of expenses at the enterprise and their characteristics is resulted. The classification of cost management methods of business entities is developed and proposed separately. The crisis of the national economy, which covered a period of twelve years, significantly changed the approaches of domestic entrepreneurs to management. Problems with sales, unprofitable activities required a focus on crisis management (crisis financial management), loss control, maintaining a stable level of profit, which was achieved primarily through cost management. The purpose of the article – based on a critical assessment of scientific developments in the field of cost management to determine the essence, characterize and develop a classification of cost management methods in the enterprise. The theoretical and methodological basis of the study were the works of domestic and foreign scientists, leading scientists and practitioners in the field of cost management in the enterprise. General theoretical methods were used in the research process. The system method was used in the study of theoretical aspects in the field of cost management. The method of analysis was used in the study of the most popular methods of cost management and their chronology of development. With the help of abstract-logical method – substantiated and presented conclusions and proposals for improving methods of cost management in Ukrainian enterprises. The article defines the essence of cost management methods based on semantic analysis of the term "cost management method" using a number of economic terms to form its structure, as well as determining the place of cost management methods in the cost management system in modern enterprise. A brief description of the most common methods of cost management in the financial and economic activities of economic entities, indicating their positive and negative sides. Based on the above characteristics, a classification of cost management methods was developed and proposed.

With the maturity of network technology, the deterministic factor of a 'successful' web site does not as much depend on its connectivity to the Internet, rather the content of web pages plays a more important role. The inclusion of dynamic data, for example, has become an increasingly desirable feature of a web page. Web servers that support dynamic web pages are capable of retrieving data at the time of user requests. Rather than being statically included in the web page, these dynamically retrieved data may physically reside in various file systems or database servers across the Internet.JAVA, a new object-oriented programming language, has become a buzzword since its introduction by Sun Microsystems in 1994 [1, 2, 3]. It was claimed that JAVA, via its ability to embed applets in a web page, would make the content of a web page alive and dynamic. Data and information on a web page can now be updated dynamically when users request them.In this paper, we discuss our experience of developing JAVA applets that use various types of JDBC (JAVA Database Connectivity) drivers to connect to and then manipulate data stored in SQL (Structured Query Language) database servers. We first start with the discussion of general client/server model involving JDBC, and then introducing the procedure of setting up programming projects employing this approach in an undergraduate database course.

In this paper, it will be explained about an application which able to analyze the quality of java program code in implementing Java Database Connectivity (JDBC). The analysis will be based on existing best practice in implement JDBC. To analyze JDBC, bugs patterns are needed to be compared with existing best practice. Various methods are available to be used in constructing this kind of application, but in this paper, static analysis non-linear method is used in designing this application. Static analysis means the java program code will be read and analyzed without executing. Non-linear means the java program code will not read sequentially, but it will follow the flow of the program code itself. And this application will be called Bedhigasan, which able to detect bugs pattern in implementing JDBC and it will report those bugs to the web page including with location of the bugs.

The human resources of an enterprise are understood as the total number of people with the ability to work, who ensure the economic development of the enterprise and are the basis for the development of the enterprise. Human resources are a prerequisite and a subject of market competition of enterprises. They can stabilize the development of enterprises, and enterprise human resource management is also an important component of enterprise management. Human resource management of an enterprise consists in understanding the human resources of an enterprise and then developing a set of scientific and effective management plans that correspond to the current situation and development of the company. Systematic human resource management of an enterprise is the most common method of human resource management in enterprises. This management method mainly involves a reasonable allocation of talents, a detailed allocation of responsibilities, and clear responsibilities. In order to achieve the best development of the enterprise, it is necessary to carry out strategic design of the human resource management system.

Presents a client/server concept for the secure transmission of ECG data from a SQL-database server via Internet/Intranet to multiple JAVA-based presentation clients. Architectural aspects of server and client are considered. For the server database access, both ODBC (Open Database Connectivity) and JDBC (Java Database Connectivity) interfaces are discussed. Secure Data transmission requirements are fulfilled by a SSL (Secure Socket Layer) implementation. Client and server prototypes were tested in different realistic system environments. In integrated healthcare, similar systems could enable healthcare professionals to access shared patient-related collections of cardiological data.

Java has emerged as a popular programming language and platform for Web applications. JavaBeans defines the software component model in the Java programming language that is used for creating reusable, coarse‐grained components. Beans are used in numerous complementary technologies including Enterprise JavaBeans, Java Abstract Windowing Toolkit, Java Database Connectivity, JavaMail, and Java Management Extensions to create software components. Beans provide a hybrid of object‐oriented and loosely coupled architectural styles, where the interaction between components is in the form of both events and method calls. This chapter focuses on the support for component technology in Java, specifically in the form of JavaBeans and its technology variants that fulfil the needs of Web application development. The chapter also discusses the role of JavaBeans and its technology variants in architecture‐based software development.

Call Level Interfaces (CLI) are difficult to use mainly in intensive database applications with many Create, Read, Update and Delete (CRUD) expressions. As low level API, they are not suited to promote the development process of business tiers as reusable components, leading to the need of writing additional source code whenever a new CRUD expression is needed. To tackle this gap, this paper proposes an architecture for building reusable business tier components herein referred to as Reusable Business Tier Architecture (RBTA). It relies on a single customizable wide typed service to address a business area, such as accounting. The typed service is able to manage all the required CRUD expressions for that business are, which are deployed at runtime in accordance with the user's needs. The only constraint is that the required service to manage each CRUD expression must be a sub-set of the implemented wide typed service. A proof of concept based on Java Database Connectivity (JDBC) is also presented.
