Abstract: Accurately and efficiently managing mechanical parts database is extremely important and pivotal in the machinery industry. In this paper, a dynamic management database system of mechanical parts is established by the Microsoft Access database management system and the VB visualized integrated development environment. This system adopts ADOX object to establish a new database and edit the existing database dynamically, applies data files, ADO and ADOX object to dynamically manage database, and utilizes Datacombo control to realize the selection of data. Being simple, convenient and feasible, this system is an intelligent man-machine interactive operating system, which enhances the work efficiency and substantially decreases repetitive operation.

Abstract: The dormitory management information system is designed based on the basic principle of MIS and database implementation techniques. The design mainly uses the C/S model, and the development tools are Delphi and the Microsoft Access. From the system demand analysis to the function module design and the database design, to system interface, the whole process of construction of dormitory management information system is introduces in detail.

Abstract: This paper studies the frequent subgraph query issues on graph data set. Combining with the approach that frequent subtree extend to frequent subgraphs proposed by Xian-Tong Li, we propose a new algorithm. This algorithm improved its storage structure avoiding direct subgraph isomorphism judgment, reduced the stability requirements on graph set, and enchanced the overall efficiency of the algorithm.

Abstract: Optimization method ofmassive dataquery is researched in this paper.In the modernInternet environment,the datahas the characteristics oflarge amount of information, complexity, disorder, andchaosassociation. Using traditionalqueried methodsoftenrequirea lot oflimitedconditions, witha lot of drawbacks such as time-consuming data query, moreineffective queryand low efficiency.To this end, anoptimizationmethod of massive data query based onparallel Apriori algorithm is proposed in this paper.The massive dataare made simplification processing andredundant data are deleted to providedata foundation for fast and accuratedataquery.Effectiveassociation rulesof the massive data are calculated, in order to obtain the relevantof the target data. Based onAprioriparallel algorithm,massivedata are processedto achieveaccurate query. Experimental results show thatthe use ofoptimization algorithm for massive dataquerycan improvethe query speedof target data and it has a strong superiority.

Abstract: according to the current situation of small and medium-sized library carried out feasibility analysis and the actual demand. The library's basic business processes are described. Combining with the knowledge of library and database technology to design each module. The system using the Windows XP/Windows 6.0 as system platform, using Visual basic 6.0 as a front-end application development tools, Microsoft SQL Server 2000 as the background database. Through to the small and medium-sized books management system management system requirements analysis, functional module division, database model analysis, designed the database structure and application. Due to the use of computer management, improved the traditional manual management way, improve the management level.

Abstract: The development of management information systems in the construction of university personnel management subsystem as the background, discusses the basic principles and methods of management information systems concepts , structure and system development , a detailed description of the technical background in database technology of " Personnel Management management system , "the basic functions and implementation process.

Abstract: Visual C++6.0 is selected as development tools while Access 2000 of Microsoft is used to build database, and the technology of ADO is adopted to achieve the connection between them. Though the secondary development of API function provided by SolidWorks, the query module is taken as a plug-in integrated in SolideWorks, which achieves the automatic query.

Abstract: the security of database system as the core component of data storage has been increasingly important. Effective audit of the database system can reduce the potential security risk. Practical database audit system should not affect the operation of the existing system which uses audited database. This paper presents and implements a multi-protocol database audit system based on bypass mode, and has a detailed description of the function of each module and the interface between them. This paper designs a detailed database audit policy to achieve effective audit. In the second half of this paper, we focus on the implementation of the key technologies which contain Zero-copy and flow table. Keywords- database; zero-copy; flow-table;policy; audit

Abstract: The Internet has greatly expanded the scope of the use of network information resources and scale, people search and ease of access to information resources and autonomy is also greatly enhanced, but also led to information sharing network of intellectual property protection and infringement issues. This article lists the use of network information resources and violations of copyright law and civil law from the perspective of legal thinking.

Abstract: For vocational colleges, talent is the key to their development and efficient human resource administration is the power to move the college forward. As a vocational college, how to administrate its staff according to its own characteristics has always been the emphasis of the college. In vocational colleges, human resources can be comparatively complicated and there is great fluency in their staff and there is a great variety of the period of teaching and rewards among all the staff. To the human resources department, some traditional file administration system cannot satisfy the current vocational college human resources information administration. It is very important to use modern information technologies to build a scientific and efficient human resources management system for vocational colleges. In this paper, we present the design and implementation of the management system combining with advanced database technology.
