| 摘 要: 常规的数据库应用受制于字段结构的限制，虽然简化了处理流程，但处理效率比较低下，往往形成应用的 瓶颈。使用联合字段对数据库结构进行优化，使原有的重复数据得以整合，结合SQL语言与单一类型存储，可以有效提 升数据的检索效率，快速产生初级可选集。对可选集的操作可以使用原有的数据库系统，也可以使用定制的数据库，定 制数据库不但可以摆脱数据库系统对开发过程的限制，而且在数据的处理与加解密方面更加主动灵活，是小型数据库应 用开发的一个趋势。 |

| Abstract: Conventional database application is restricted by the field structure,although simplified the processing flow,but the processing efficiency is low,often the bottleneck in the application.Using united fields to optimize the database structure.The original repeating data can be integrated,with the combination of SQL language and the single type of storage,can improve the efficiency of data retrieval,fast generation primary optional set.On the optional set operation can use the original database system,can also use the custom database.Customize database can not only get rid of the limitation of database system development process,but also more initiative and flexibility in the data processing and encryption and decryption,is a development trend in small database application. |
