数据库管理系统的程序是什么?
如上所述,用于计算、分析和图表。
数据纯粹是数字。
如何分别创建数据库表和计算/分析/图表?例如,我可能想从数据库等中创建一个单独的“countif”表。
请建议该程序的名称及其优缺点。
As above, for calculation, analysis and graph.
The data is purely number.
How do I create the database table and the calculation/analysis/graph table separately? For example, I might want to create a separate table of "countif" from the database and etc.
Please suggest the name of the programme and their pro and cons as well.

数据库系统是一个好的开始。 Mysql 和 Postres 是免费的,尽管有很多非免费的替代品,例如 Oracle 和 SQL Server。
分析和计算由查询负责,如果经常重用,通常将其作为视图存储在数据库中。
除此之外,这个问题太笼统,无法提供任何更有针对性的建议。
A good start is a database system. Mysql and Postres are free, although there are plenty of non-free alternatives, such as Oracle and SQL Server.
The analysis and calculation is taken care of by queries, usually stored as views in with the database if they are reused often.
Beyond that, the question is too general to give any more directed advice.
你的问题非常模糊,通常在 RDBMS 中你使用 SQL(结构化查询语言),请参阅此处了解更多信息 http://en.wikipedia.org/wiki/SQL
Your question is very vague, In general in a RDBMS you use SQL (Structured Query Language), see here for more info http://en.wikipedia.org/wiki/SQL
