Serialized data in a MySql Database to use in a Business Intelligence tool

I have a database (MySql) and need to store some results from a web service monthly. The data can have 10 results today but may have 200 next month.

I need to use a BI tool to create charts and what not.

Someone proposed to serialize the data and save the blobs in the database, while the solution seems to work, I have a gut feeling that when the time comes to hook it up with the BI tool, hell will break loose.

Has anyone had this issue before?

Thanks

Edit: adding extra info.

The problem is that we haven't chosen the BI tool yet. But what it needs to开发者_JAVA技巧 do is create charts for the results. Some of the results come from Google Analytics. So we will be charting number of visitors to a site for the last 6 months. Or Number of viewed pages.

The answer is simple: do not store Serialized data in a database.
Do some research, atomize your data and create data structure.
Once you've done it, you will be able to use any BI tool in the world.
That's the purpose of a database and what distinguishes a database from a flat file.
