本文主要对这一问题进行了讨论，并提出了实时数据库结构优化和解决实时数据访问冲突的解决办法。

This issues are mainly discussed in this article, then the structural optimization of the real-time database and the measure to resolve the access collision in the real-time database are put forward.

与SDO形成对照，EII是提供实时数据访问的数据集成服务器，通常用表来表示不同种类的数据，而且它使用基于SQL的API。

EII, by contrast, is a data integration server that provides real-time data access, typically represents heterogeneous data as tables, and usually employs a SQL-based API.

In any event, the mock implementation should definitely not try to handle every possible stock symbol or access a database with real-time data.
