Blob support?

[pmcmicha]

I am looking into using blobs with DB2, but I cannot find a whole lot of information about it. From my understanding the file itself is not stored in the database, but in the filesystem. The database just creates a pointer to that file in the filesystem and you can now reference it. I already do this with the file in question, so what is the benefit of using blobs over a straight database pointer? If there is a good reference somewhere, I would like to know this as well.

Number of objects: Less than 10,000
Size of objects: 200MB max per object

Thanks in advance.
