Abstract: Nowadays, object-oriented design is the trend of software design patterns, and the database connection pool is one of the important research topics. The paper firstly describes the basic principle of connection pool under traditional, tomcat and hibernate modes. Based on that, a new connection pool method is proposed, and these four methods are experimentally simulated in java language at last. The comparative analysis has verified that the presented connection pool owns the optimum access time and it can greatly improve the access efficiency of database.

Abstract: Proposed a extend design pattern, which oriented distributed environment. Design framework in which import some components, such as command bus, command executor. Design the structure class diagram of the pattern. Expatiated components’ specific function, and analyses the command execution process in the pattern. Based on the pattern, when developers design command classes, there is no need to consider how to sequence the command object and send it to server, and they don’t worry about receiving data from server and anti-serialize from the received data. Conclude that developers can use command pattern in a network transparent manner in accordance with the original way.

Abstract: In the current implementation in the form of software,Web-based B/S structure has been a wide range of applications.With the gradual expansion of the scale of software for such systems need to have a good framework to support the development and maintenance processes. Quality system plays an important role in the whole system.This paper describes the design process of a good Web-based system framework from the perspective of practical application.Through practice, this framework can well support large-scale software development and maintenance process, the various types of cost savings for the enterprise.

Abstract: Detection of design patterns in software design phase possibly ensures the non-functional requirements, regarding performance features, before investing the implementation. We formalize the structural UML class diagram using graph. By applying graph matching technique, we propose an alternative of subgraph matching algorithm to extract the local properties of the UML class diagrams and perform the detecting of subgraph of possible design patterns found in the target software design model.

Abstract: Patterns have become a more effective way on the knowledge use of the HCI domain. These patterns are mainly oriented to different tasks, which are too coarse-grained to be easily implemented. And it is not given that how to use these patterns to built user interfaces in engineering way. Furthermore, many different patterns are oriented to different models in the model based on user interface (UI) development, which are hard to be integrated into the UI development tool. In point of increasing UI knowledge reuse, every UI is divided into many presentation units (PU), which reduces the grain of UI. Next, the UI feature space is given through three facets and various relations among these facets. Therefore, the Engineering-oriented User Interface Design Pattern (EUIDP) is proposed from the interior model, the presentation model and the operation model. As a case, the Grid EUIDP is explicitly described according to the form of EUIDP. Finally, the conclusion and the further work are discussed.

Abstract: With development of software scale, programmer has been noticed the importance of design pattern. Each pattern has different realization in different platform. As the object-oriented technique develops, application of MVC pattern has been widely used. MVC pattern doesn’t only used in component construction, but also it used in large-scale object-oriented system design, such as e-commerce system. This paper discusses application of MVC on JAVA platform, and analysis advantages and disadvantages of MVC and MVC2.

Abstract: According to the physical characteristics and safety requirements, the evaluation levels of special electromechanical equipment were created. The five-layer neural network model was created according to the multi-layer neural network model. The first layer is input layer, the last layer is output layer, and the others are hidden layers. The software structure of evaluation system was designed, and the main class diagram was designed with UML. The relations among views, data model and dispatch controller were designed with MVC pattern. The factory method was used to instantiate view objects according to the object creation pattern. The ITERATOR pattern of structural pattern was used to find out view objects in the view object aggregation. The strategy pattern of behavior pattern was used to encapsulate different neural network algorithms.

Abstract: This article is to design and implement a perception interactive terminal software based on android platform. Its main function is appliance control, energy consumption analysis, timing tasks, electricity alert, device management and system settings. The software provides the perception interface and function to grid companies and consumers. It achieves the inquiry of electric bill, electricity price and electricity consumption, the intelligent appliance control and the electricity management of household. It also has some practical value for smart grid construction. This paper mainly describes the functional architecture and implementation of the perception interactive terminal software.

Abstract: Analyzed and recomposed to J2EE architecture, and during research of design pattern, the document bases on existing frame for achieving more application-layer reuse to engineer framework, and forms an optimal design pattern of electronic commerce. The pattern is actualized in on-line shopping system found on J2EE. The experiment results show that it reduces system development cycle, optimizes system structure, enhances the system's performance, and decreases the risk and the cost in software development when the framework and design pattern are combined artfully to use on electronic commerce

Abstract: Introduced key technologies of Automated Testing Framework. Firstly, started from the opinion of software reusing, combined with the characteristic of Object-Oriented software and based on analyzing the feasibility of software reusing, this paper discusses the significance of Design Pattern. Secondly, in order to make the framework reusable, expansive, maintainable, referenced the idea of XUnit framework, Pattern generating Framework, this paper gives detailed introduction about the key technologies that are used in the ATF framework. The framework is implemented by using and applying many existing related design patterns and techniques such as Command, Observer, Composite, Adapter and Template Method, etc. In addition to the above, this paper also describes (Automated Testing Framework for N.E.W.), which is apply ATF to the functionality testing of N.E.W. It also analyses the test results, the framework’s shortage and provides the improved advices.
