Hello Friends.
We are re-designing our App and we have a critical question, what's the best way (in terms of performance) of using TIFF images (about 20K size) with Oracle.
Currently we have a Windows shared file server and we create the tiff images there under a huge directory structure (like /images/ddddmmyy/aa/bb/001, then /images/ddddmmyy/aa/bb/002, etc, etc). Our database is usually in LINUX version 10, 11 or 12.
We create about 200,000 images per day, keep them for 60 days and then remove that structure.
Our Web app (developed with .NET) reads those images just to display them on a Web Session (IE).
As you can see, what we are doing now works fine. But network sometimes is an issue and also it's hard to keep synchronization with our DR server, backups, etc.
Are we taking the correct approach? It would be better to have the images in CLOB or BLOBS for better performance? If so, can you provide me some suggestions on the best way to implement this?
As I mentioned, performance is the KEY FACTOR and the most important item to consider in this design.
Thanks,
Diego

You could use BLOB to store TIFF in Oracle DB.

No, absolutely not. I missed the point that OP is actually comparing the performance of retreving the tiff images. A file system is much better. Oracle would just add more pain and DB layer will be considered the culprit later stage. And you are correct, not that Oracle can't store it, however cannot improve performance better than web application directly interacting with file storage system.

Hello Littlefoot ,
We also use Oracle to save the data, customers, clients, etc. Of course we need the database. Each image has information that is also saved inside the Database.

I believe that that is the OP's question. And it is related to Oracle in as much as the rest of the data is maintained within the database. Personally, I'm a fan of keeping everything in one place i.e. the database. If the file system gets out of sync with the database entries, you have a nightmare on your hands. i.e. a load of content (the TIFFs) with no way of referencing it. A 20K TIFF file is nothing but, like you say, it's the sheer volume that is the problem.
I suspect that the only answer for the OP is to test it.
