 After building successfully, TDengine can be installed by:
 ```bash
 sudo make install
 ```

 Users can find more information about directories installed on the system in the [directory and files](https://www.taosdata.com/en/documentation/administrator/#Directory-and-Files) section. Since version 2.0, installing from source code will also configure service management for TDengine.
 Users can also choose to [install from packages](https://www.taosdata.com/en/getting-started/#Install-from-Package) for it.

+If you don't want to run TDengine as a service, you can run it in current shell. For example, to quickly start a TDengine server after building, run the command below in terminal:
+```bash

 在TDengine的设计里，**表用来代表一个具体的数据采集点，超级表用来代表一组相同类型的数据采集点集合**。当为某个具体数据采集点创建表时，用户使用超级表的定义做模板，同时指定该具体采集点（表）的标签值。与传统的关系型数据库相比，表（一个数据采集点）是带有静态标签的，而且这些标签可以事后增加、删除、修改。**一张超级表包含有多张表，这些表具有相同的时序数据schema，但带有不同的标签值**。
 
-当对多个具有相同数据类型的数据采集点进行聚合操作时，TDengine将先把满足标签过滤条件的表从超级表的中查找出来，然后再扫描这些表的时序数据，进行聚合操作，这样能将需要扫描的数据集大幅减少，从而大幅提高聚合计算的性能。
