Calling SQL database and processing unit from NT services

Question

I need to process files whenit get dropped to folder and update details in the DB.

I have an NT service written which detects the file drops

Questions hovering my mind:

1- Should I use this same NT service to process it?

2- Is NT service thread safe by defualt in nature?

3- Should I process files within NT service or is there a better way to processing files, like handing over files to different program..

4- Does it make sense for NT service to connect to DB? (I am not sure if DB and NT service logic would reside in the same machinein future)

Answer 1

When we have had a similar situation, we have done it as follows:

• First service, picks up the file validates its contents and imports the data into staging tables.
• Second process takes the information from the staging tables and sends it into the system.

This is similar to the ETL - Extract Transform Load, used for dataware houses.
