Beijing and Shanghai Chinese Translation Service in The field of Database design


2.7 Database design
2.7.1 Operation arrangement
The project is to arrange the system related operation including Drilling Dynamic Info. Management, Production Technology Info. Management, Oil/Gas Production Info. Management, Reservior Dynamic analysis management, Development special technology report management etc. meanwhile, it is to design concept model, physical model and logical model of database.

2.7.2 Concept model
The project is to refer to dynamic database design criterion for CNODC oilfield development and production, design the entity code and data code architecture for development database information management code system (hereinafter called information criterion code).
In order to satisfy the construction requirements of SSKOC dynamic database system, development information criterion code is to sort and code based on database data organization structure, operation activity logical data organization structure, metadata organization structure, data storage organization structure and operation management type and be conformed to following principle:
1. Unique
Unique means data code and ID code in SSKOC enterprise scope is unique and one to one, each item in data code design has only one code, and one code marks one item.
2. Complete
It is to record all related code items to ensure information criterion code completeness and effectiveness when coding for SSKOC dynamic database information criterion code.
3. Extensible
It is to consider not only the current related sorting project but also the future extension of database application with the constant construction at the time of coding.
4. Orderly
SSKOC information criterion code is to refer to not only many subject sorting projects, there are tightly collaborative working relationship in each project. the coding is to be orderly organized and arranged to ensure rapid search and information organization.
5. Easy
Coding is to be simple for easy remember, management and usage.

Beijing Mandarin Chinese Translation Service Company has translated many technical documents in the field of Database design.

2.7 数据库设计
2.7.1业务梳理
本工程将根据工程规范书的要求，对本工程系统所涉及到的业务进行梳理,内容包括钻井动态信息、采油工艺动态信息、 油气生产动态信息 、油藏动态分析信息、开发专项技术报告信息等。同时对数据库的概念模型、物理模型以及逻辑模型进行设计。

2.7.2概念模型
本工程将参考CNODC油田开发生产动态数据库设计规范，结合买方公司的实际情况，对开发数据库信息管理代码体系进行实体代码和数据代码架构设计（以下简称为信息标准代码）.
为满足SSKOC动态数据库系统的建设要求，开发信息标准代码将按数据库数据组织架构、业务活动逻辑数据组织架构、元数据组织架构、数据存储组织架构并按照业务管理类型进行分类编码，并遵循一下原则：
1、唯一
唯一性是指在SSKOC企业范围内进行的数据编码与其标识代码具有全局唯一性和一一对应性，在数据编码设计中每一个条目只有一个唯一代码，一个代码只标识一个条目。
2、完整
在为SSKOC动态数据库信息标准代码编码时，要录入所有涉及到的代码条目，以保证信息标准代码的完整性和有效性。
3、可扩展
编码时不仅要考虑到目前已经涉及到的分类项目，充分考虑今后随数据库应用不断开发建设所允许对新项目的扩充性。
4、有序
SSKOC信息标准代码不仅涉及到多个专业的多种分类项目，各项目间都存在紧密协作的工作关系。编码必须做到井然有序的组织与排列，以达到快捷方便的查知和信息组织的目的。
5、简单
编码化繁为简，便于记忆、便于管理，便于使用。
