Program execution traces (simply traces in the rest of this paper) which include data/control dependency information are indispensable for new kind of debugging, such as back-in-time debugging. We aim to support debugging of Java programs. Traces of practical programs are prone to have vast amount of complex data, which makes it difficult to develop practical debuggers to use for them. In our previous...
As computer systems become more complicated, monitoring dataflows in a system becomes important for maintaining its performance. However, because conventional methods of dataflow monitoring are either too fine-grained or too coarse-grained, it is difficult to analyze application-specific performance metrics. In this paper, we propose a dataflow logger with suitable granularity for performance analysis...
IT complexity in enterprise today continues to grow at a dizzying rate. Technology innovation, vendor heterogeneity, and business demands are major reasons why organizations are exposed to new risks, based on the gaps opened between the options and features of each IT element and product, and how they are implemented to support a well-defined policy and company strategy. Moreover, the impact of such...
Database-centric applications (DCAs) usually contain a large number of tables, attributes, and constraints describing the underlying data model. Understanding how database tables and attributes are used in the source code along with the constraints related to these usages is an important component of DCA maintenance. However, documenting database-related operations and their constraints in the source...
In the era of big data, data analytics, business intelligence database management plays a vital role from technical business management and research point of view. Over many decades, database management has been a topic of active research. There are different type of database management system have been proposed over a period of time but Relational Database Management System (RDBMS) is the one which...
The progressive transition in the nature of both scientific and industrial datasets has been the driving force behind the development and research interests in the NoSQL data model. Loosely structured data poses a challenge to traditional data store systems, and when working with the NoSQL model, these systems are often considered impractical and expensive. As the quantity of unstructured data grows,...
This paper analyzes the potential of Semantic Web technologies to support innovation in industrial scenarios. The study focuses in particular on RDF stores, the software components dedicated to the storage, representation and retrieval of semantic information. Starting from a literature review, a qualitative analysis is carried out considering a set of these systems. RDF stores are evaluated to find...
With the trend of mobile enterprise information systems, security has become the primary issue as it relates to business secret, decision, and process control. Hence, we carry out a fully customized framework to emphasize on security from trust authority of the cloud certificate authority server, and to guarantee security with the process of the software developments. The core object model, named...
In a Dimensional Model of Data Warehouse, process of designing conceptual schema based on user requirements face some challenges due to data sources may lack some important elements. One way to improve schema is by utilizing alternative sources of knowledge that act as DW additional data sources. Since past few years, there are several researchers who present the use of Ontology to improve several...
The popularity of the Internet and the rapid development of Web technology and its application make the XML technology developed quickly. More and more programmers store the data in XML form. With the large number of XML documents, applications need to continue to deal with XML data, access and update the XML data. Then XQuery is emerged. This paper introduces the XQuery language briefly, discusses...
The application system features in small or medium-sized enterprise lie in the greater flexibility and speed, safety, high performance-price ratio. Traditional J2EE framework can not adapt to these needs, but the system application based on SSH(Struts, Spring, Hibernate) technology can better satisfy such needs. This paper analyses some integration theory and key technologies about SSH, and according...
SSH is a development mode which is widely used in current enterprise's development. In order to make the project development more efficient, with the online fund trade platform for example, this paper deeply discusses the problems of distributing Action and Hibernate's lazy loading in actual development with SSH mode, and puts forward the improvement project, which greatly increases the development...
This paper analyzes the Struts framework, the Hibernate framework, and the combined framework of Struts and Hibernate. The paper also discusses how to use the combined framework to realize the application and design of the management system for scientific research projects. This system can efficiently solve the problem of the poor expansibility and poor maintainability in the application of traditional...
Enormous data have become a trend and increasingly important to data analysis and mining. It is important and urgent to extract useful information from enormous data. The processing shall be accurate. Therefore, the study of enormous data is very promising and the extensive and in-depth study is also worth doing. To ensure stable and efficient operation of the system, data algorithm analysis, database...
Web GIS is becoming the developing hot pot for GIS With the development of Internet technology . Geographical Information System (GIS) is an information system which stores analyzes and visually express spatial data . WebGIS can Provide not only simple text and data , but also graphics and images to more and more people. WebGIS is the outcome of Internet development and information sharing . However,...
Data persistent is an important part of development in JavaEE, and it is an intractable problem in process of designing E-government system. However, we usually use a single framework to build enterprise-class applications, such as mixed logic of reuse program and poor expansibility. The realizing scheme of how to use abstract factory pattern, DAO pattern, VO pattern, singleton pattern and Hibernate...
To study the SVG technology and J2EE technology, and take the power industry requirements as a starting point, this paper designed a B/S-based power graphics development platform. It can not only develop the standard SVG-based power graphics, but also can associate the graphics with data models closely. So the data information can be shown by the intuitive of the graphics, and it is of great significance...
Object-oriented programming is the most successful programming paradigm. Relational database management systems are the most successful data storage components. Despite their individual successes and their desirable tight binding, they rely on different points of view about data entailing difficulties on their integration. Some solutions have been proposed to overcome these difficulties, such as Embedded...
Now, it's a popular technology of Web programming development based on J2EE platform Framework, which Struts framework that based on MVC design pattern divided the system into the controlling part, business logic part and view one, and achieved the decoupling between layers, Hibernate framework offered a method of packaging a lightweight object for JDBC, and reduced the difficulty of developing business...
With the popular J2EE architecture, Using the MVC design pattern and two common framework of Struts and Hibernate in JavaWeb area, Design and implementation of comprehensive statistical information management system, and describes the system implementation process.
