The paper takes the project of Xi'an international airdrome infrastructure management information system as an example and validates its feasibility and demonstrates its applicant value, which realizes the share of infrastructure data and establishes the basic for further development.

在现阶段，由于面向对象数据库自身发展的不成熟和互操作技术的不完善，本文提出采用较为先进的空间数据引擎技术结合关系数据库或对象关系数据库建立统一的数据模型和统一的数据库管理系统，打破空间数据固有的管理模式和界限，实现空间数据和其他属性数据的集成，为地理信息的共享奠定基础。

For the open style controlling system, the controlling system nased on the PMAC is built. The layered step-up controlling system flatform is inplemented. Based on the control demand of the welding position,speed and stabilization, the three rings servo system that using the position as the external ring , the current as the internal ring and the speed as the centre ring. Using the Borland C++ builder 6.0, the PComm32PRO from Delta Tau and the SQL Server as the data bank engine.

在Borland C++ builder 6.0开发环境下和Delta Tau提供的PComm32PRO动态链接库，采用了功能强大的SQL Server作为数据库管理引擎，开发开放式专用焊接机器人系统的控制软件平台，主要包括以下模块：系统设置模块、状态监控模块、运动控制模块、专家系统模块、数据管理模块、在线指令模块和通讯模块。

Standalone less than two megabyte executable which does not rely on the presence of the database engines of other products.

独立的不到两兆字节的可执行文件，其中不依赖於在场的数据库引擎的其他产品。

The size specified for the primary file must be at least as large as the primary file of the model database.

如果指定了辅助数据文件或日志文件，但未指定该文件的 size ，则数据库引擎将以 1 MB 作为该文件的大小。

Axion - AxionAxion is a small, fast, SQL and JDBC compliant relational database engine written in and for the Java programming language.

Axion 是一个小型的，快速的SQL和JDBC 适应的关系数据库引擎，由JAVA编程语言编写并且用于JAVA语言。

Any SQL database engine can be used making Bacula very flexible.

任何 SQL 数据库引擎可以使 Bacula 变的灵活。

Support for clusters of heterogenous database engines.

对异构数据库引擎构成的集群的支持

Thirdly, in order to manage these data better, the paper advances the organization methods of data of commixed Database of Geo-spatial Framework model by integrating some advanced database technologies such as RDBMS and the Spatial Database Engine, namely on the basis of database and the data of Geo-spatial Framework divided in a preceding part of this paper, it describes layer-delaminating, block-dividing, slice-connecting, map-dividing and BLOB etc. to organize spatial data, including DLG, DOM, DEM, and thematic data, taking example for the data of urban planning. At the same time it also realizes integrated management of these data.

然后，本文以管理这些地理空间框架数据为主要目标，集成关系数据库管理系统以及空间数据引擎等相关技术，提出了地理空间框架混合数据库数据组织方法，即以地理空间框架数据库为基础，以分类后的地理空间框架数据为对象，通过采用分层、分块、连片、分幅以及大二进制对象等方法对基础空间数据(包括数字线划数据、数字正射影像数据、数字高程模型数据)和专题数据进行统一组织，并实现了这些数据的关联一体化管理。

The system use SQL Server as background database engine, Power Builder as foreground development tool.

该系统以SQLServer作为后台数据库引擎，以PowerBuilder作为前台开发工具，包括了题库管理、考试管理、成绩管理等功能。

Berkeley DB offers many of the storage services transactions, concurrency, andrecovery of relational database engines. It is closer to a file system in that it storesany kind of data in any format, but provides no easy tools for ad hoc queries.

Berkeley DB 提供许多存储服务-事务，并发，恢复，这些关系型数据库引擎，更贴切的说它和文件系统很相近，因为可以任一种格式存储数据，然而没有提供很简单的工具在 ad boc 查询的时候。
