存储对象在数据库中

我有很多对象，每个都可以有许多不同的属性。很多属性重叠，例如，许多对象都有属性name。
由于有很多类型的对象，如果有一组对象具有相同的属性集合，那么它将需要大量的表。

I have lot of objects, each can have many different kind of attributes. a lot of the attributes overlap, for example, many objects have the attribute "name". Since there are many type of objects, if there is a table constructed for each set of objects with same set of attributes, it will take lot of tables.

目前我使用的是一个mysql，它是以这种方式存储的。

Currently I'm using a mysql, and it is stored this way.

object_id|attribute_id|data

有这样的几个表，不同的表有不同类型的数据。
例如，在整数表中，它只存储整数

There are a few tables like this, different table have different type of data. For example, in a Integer table, it only store integers

所以我可以在系统中存储所有类型的对象，并且仍然可以进行过滤并根据属性的数据进行排序。它使查询有点复杂，我不认为这是有效的。

So I can store all kind of object in the system and it is still possible to do filtering and sorting according to the data of the attributes. It make queries a bit more complex and I don't think it is efficient.

这是唯一的方式在mysql或其他关系数据库中做？
我应该尝试为这个问题找到其他数据库模型吗？

Is this is only way to do it in mysql or other relational databases? Should I try to find other database models for this problem?

EDIT
我做了一些研究我需要的是一个具有SQL力量的面向文档的数据库。

EDIT I did some research, it seems what I need is a Document-oriented database with the power of SQL.
