The quare author association turn on goes into the request of the library of quinonoid formula, vs the MS SQL Server2000 data base management system, SQL language element, the VB application program design, the VB data nbank technique steered the more thorough study and appliances, cardinal terminate to manage the demand analysis of the system to the book, the function shuttering cake curtate, the data nbank modal analysis, and designed the data nbank structure and application programs thereof.

因此本人结合开入式图书馆的要求，对MS SQL Server2000数据库管理系统、SQL语言原理、VB应用程序设计，VB数据库技术进行了较深入的学习和应用，主要完成对图书管理系统的需求分析、功能模块划分、数据库模式分析，并由此设计了数据库结构和应用程序。

The technique of Delphi database steered the in-depth study and the appliance, and the library of cardinal consummation paraquinones managed the system's demand analysis, function shuttering cake the curtate, database the modal analysis, amalgamation to have this design the database structured the sumed the appliance of procedured.

本文结合中小型图书馆管理系统，对数据库管理系统、SQL语言原理、Delphi应用程序设计，Delphi数据库技术进行了较深入的学习和应用，主要完成对图书馆管理系统的需求分析、功能模块划分、数据库模式分析，并根据具体要求设计了数据库结构和应用程序。

The mapping rules between heterogeneous databases were analysed and the mapping to PCEDM database from daily data table of oil wells was established according to the features of exploration-development database and the PCEDM database, furthermore the data in this table were transferred into PCEDM database based on SSIS.

最后，分析了异构数据库间的映射规则，根据勘探开发数据库和PCEDM数据库的的结构特点，建立了油井日数据表向PCEDM数据库中的映射，并基于SSIS将表中数据迁移到PCEDM数据库中。

ParaBase system also shows that the technical plan for"YH-3"parallel database system is feasible and successful and provides important supports both in techniques and in prototype for the final implementation. Owing to the prototyped system the roundabout course in the final implementation of"YH-3"parallel database system may be avoided or lessened. In addition, this prototype system provides an ideal platform for further parallel database researches too.

ParaBase的实现在现有机器环境和数据库环境下最大限度地验证和支持了&半重写变换&模式实现并行数据库系统的思想并研究其实现效率；证明了&银河-3&并行数据库系统技术方案是可行的和成功的，并为&银河-3&并行数据库系统的最终系统实现提供重要的技术支持和原型支持，使系统实现时不走或少走弯路；此外，该原型系统为进一步研究并行数据库技术提供了一个实验平台。

Start with the network application in bank ,this article introduced the database safe and encryption technical, defined the safety of database, analysed the basic roll-over protective structure of database system and offered data safe major means, discussed the range and characteristic of database encryption technology .

本文从网络在银行业中的应用入手，就数据库安全与加密技术介绍了数据库安全的定义，分析了数据库系统的基本安全架构及其提供数据安全的主要手段，讨论了数据库加密技术的特点、范围以及对数据库管理系统原有功能的影响。

If a "reasonable" notion of database consistency is to be supported (I.c. the database system is to enforce it automatically), there are bound to be" conflict" situations where one transaction comes into an access conflict against some other transaction. If await is to be avoided,some means of a negotiated settlement of the conflict must be provided, thereby dragging the users into the details of concurrency control.The single-database model is more appropriate-ate than the multiple-database model in an environment where it is difficult to determine in advance logical partitions of the database that correspond to work to be performed, and the users closely cooperate.

如果一个数据库一致的合理观念要得到支持（即数据库系统要自动实行这个观念）、一定会有矛盾的情形产生、在这种情形中一个业务与其它业务产生存取矛盾如果要避免等待，就必须提供某种协商解决矛盾的方法，从而迫使用户详细了解并行控制单一数据库模式在某一种环境中比多个数据库模式更恰当，在这个环境中，要事先确定与要执行的工作相适应的数据库的逻辑分割是很难的，同时用户们又紧密地合作在一起。

But we don't care about Battlegrounds.
