Study of Database Connection Pool in LBS Platform
Computer Engineering, 2006Co-Authors: Li JunliAbstract:In order to satisfy the demands of multi-clients’ concurrent Database access to acquire location-based information, the key technology of Database Connection pool is analyzed on the basis of the architecture of LBS. The design and implementation of Database Connection pool are done through an instance of vehicle positioning platform, which proves the efficiency of this method.

Mathematical Modeling and Performance Analysis of Database Connection Pool
Computer Engineering, 2014Co-Authors: Huo Zhan-qianAbstract:In order to configure the system parameters of Database Connection pool effectively,a Geom/Geom/c/c discrete-time queuing model with multi-server is built according to the operation mechanism of its manage process and the thought of discrete-time queuing theory.It uses the embedded Markov chain method,and the matrix of transition probability and matching recursive relations of the stationary queue length are given.The mathematical expressions of system performance measures are derived by the theoretical analysis results of the model,such as request blocking probability,average number of Connections,system utilization,and system throughput,etc.Experiments are intuitively given to prove the dependencies between Database Connection pool performance index and system configuration parameters.

Design and Realization for JDBC-based Database Connection-pool
Computer Engineering, 2004Co-Authors: Luo RongAbstract:We come out an important thinking of management of Database Connection according to the problems we meet in the development of JDBC-based dynamic web system. This paper design and realize a high-performance strategy for the Connection management based on the thorough analysis. Especially, give a deeper discuss on the transaction processing and multi-Database servers. Finally, we realize and testify the Connection-pool in our project. The result is satisfactory.

Analysis on Database Connection Mechanism of WEB Application System in Dreamweaver
2010 International Conference on Internet Technology and Applications, 2010Co-Authors: Jianming Yang, Zhaotong Zhang, Yuexia ZhaoAbstract:Dreamweaver has powerful Database access functions, using windows operating without coding can operate Database. Existing literatures only describe sequential steps, but, the network Database Connection mechanism and the steps corresponding to program code in WEB system are not further expounded. This paper analyzes Database Connection mechanism of WEB application system based on three-tier architecture, and the corresponding relationship between main steps and auto-generated code using windows operating to achieve Database access in the Dreamweaver development environment, and then discusses two more complex issues associated with Database Connection in WEB application systems development--- principle and realization of transaction processing and Database Connection pool technology.

How to Implement Database Connection in Visual Basic 6.0 Environment
Computer Simulation, 2004Co-Authors: Xu Hong-qinAbstract:The first task in Database programming is to establish a Database Connection rapidly and easily to realize the goal of data exchange. This paper first gives an introduction to the method of making a Database Connection from the VB6.0's built-in Data Control, and its limitations. Then, taking Microsoft Access 2000 and Microsoft SQL Server as examples, three different methods of establishing Connections in VB 6.0 to different types of Databases are discussed in detail. The first method utilizes ActiveX Control (ADO Data Control) to establish fast Database Connection at Window design time. The second method introduces how to establish dynamic Database Connection using ADO Object Model at program design time. The last method discusses the simplest and fastest way of making Database Connection using VB DataWindow. This paper is intended to provide a certain level of applicability and practicability.
