问题描述
我担心Rails是否可以处理金融应用程序所需的复杂聚合类型，尤其是ORM是否可以有效地处理这些聚合.在我正在考虑将其用于此用途的财务应用程序中，需要进行大量报告，以各种方式汇总详细的财务数据.没有Rails ORM的支持，我将需要编写直接SQL.但是我担心，一旦开始，Rails的其他部分可能无法正常工作，结果我可能最终会大部分使用Rails来路由其路由，而很少使用其他方法.这是一个有效的担忧，还是我不必要地担心?
I am concerned whether Rails can handle the types of complex aggregations that are needed for a financial application and particularly whether the ORM can handle these effectively.In a financial application that I am thinking of using this for, there is a need to do lots of reporting of detailed financial data, aggregated in various ways. Without support in the Rails ORM, I would need to write direct SQL. But I am concerned that once I start this, other parts of Rails may not work as well and that as a result I may end up mostly using Rails for its routes and very little else. Is this a valid concern or am I worrying needlessly?
推荐答案
ActiveRecord的限制是我在科学环境中使用Rails遇到麻烦的原因之一.您可能想看看替代的Ruby ORM，它使使用遗留数据库的工作更加轻松:
Limitations of ActiveRecord are one of the reasons I had trouble using Rails in a scientific environment. You might want to check out alternative Ruby ORM's that make it a bit easier to work with a legacy database:
- Sequel
- DataMapper
最终，尽管ORM的设计使您远离了SQL，所以很可能它们都不适合.
Ultimately though ORM's by design take you away from SQL so it's possible that none of them are a good fit.
