Database Design for a data extensive application

Hi Experts,

We are designing a data extensive application. There would approximately one thousand customers for which we'll be entering data on daily basis.

All the data entry would be done in-house i.e. customer won't be entering the data themselves. Customers would be allowed to generate reports on the data entered. Reports being generated for one customer may be using data from all one thousand customers. The guesstimate for the daily data is around 10MB for all thousand customers.

Here is how we are planning to setup the environment:

We are planning to setup two different databases on two different machines, one for transactional data and other for reporting purpose. All the customers will be using the database daily for reporting. We'll be using a service that will fetch the data from transactional database, compile it, and dump into the reporting database.

I need feedback on the following:

1. Any comments/suggestion on above design.
2. Any other better idea for load balancing for the above situation.

Deployment environment would be: Window 2003 Server, MS SQL Server 2005.

Thanks,
Imran

From what you've said, I don't see a problem with the setup you are considering... Main thing to be concerned with is the actual database designs, make sure they are designed with 3rd normal form, normalized only when truly needed, also be sure they indexes are created for the queries that reports are generated from.

Thanks for your input.

Actually I am looking for possible options so I can chose better. There'll be heavy simultaneous hits on both databases. Therefore I want to design the things in such a way that they are scalable enough for the current scenario and for the future growth of data.

Thanks again.

Additional options would be setting up replication of the databases, then allows only a portion of your customers access a server, hince a sort of load balancing. Another option, but more expensive would be setting up a cluster. Since from the sound of it, most of your heavy activity will be read only querying, you have alot of options especially with replication, its when the customers need to modify that data as well, when things get more complex and expensive.
