2.7.3 Physical model
The project is to install and deploy in two level according to the actual situation of the buyer company, firstly, it is to deploy the whole application system at SSKOC headquarter including database server, application server etc to implement distributive application of all function, meanwhile, it is to deploy data collection and process client at oilfield site to implement unified source data collection and process and distributive storage and application by system in headquarter if the condition is mature. furthermore, the project is to reserve extensible interface for future system integration with Syria government, Beijing headquarter and oilfield production scene.

2.7.4 Logical model
The project is to apply relational database design pattern to satisfy the 3rd pattern of database design avoid exceptional data inserting or deleting or inconsistent caused by unreasonable structure design, and comprehensively balance the relationship between data redundancy and efficiency according to the using frequency, table capability of each table.
The project is to be conformed to design criterion and related petroleum industry criterion, industry regulation and each principle of dynamic database for SSKOC oilfield development and production. for the existing unified code table such as solution code, well type code etc appendix table, it is to apply existing code structure to be the structure of system code table; it is to establish other code table according to actual operation and build code reference table by existing structure for future extension.

2.7.3 物理模型
        本工程将按照买方公司的实际情况，进行两级安装和部署，首先在SSKOC总部部署整个应用系统，包括数据库服务器、应用服务器等，实现所有功能的分布应用，同时，在条件成熟时，实现在油田现场部署数据采集和处理客户端，实现源点数据统一采集和处理，再通过部署在总部的系统实现分布式的存储和应用。另外，本工程将保留扩展接口，以便将来在需要的时候与叙利亚政府、北京总部以及油田生产现场的系统进行集成。

 2.7.4逻辑模型 
        本工程采用关系型数据库设计模式，充分满足数据库设计第三范式，避免因结构设计不合理导致数据插入删除异常，或数据不一致，并根据各个表的使用频度、表容量来综合平衡数据冗余和效率之间的关系。

        本工程遵循SSKOC油田开发生产动态数据库设计规范和石油行业有关标准、行业规范和各项准则。对于已形成统一规范的代码表，如措施代码、井别代码等附录类代码表，采用已有的编码结构作为系统代码表的结构；对于根据实际业务而建立的其他代码表则参照已有结构建立代码参照表，以便未来业务和应用的扩展。
