C# Console App - Producer / Consumer using database as a queue.

Hi,

I'm looking at creating two C# console applications. The first console app will produce text records (possibly multiple records concurrently) and write them to a database. The second app will take each record in the database (queue) and consume them in order that they were created deleting each record as it is processed. The two applications will run concurrently on the same machine.

Is MS SQL CE a good fit for holding this 'record queue'?

How can I safely produce and consume the records without running to any conflicts?

Thanks for any input

Unless you have very limited resources on the station, I would go for SQL Server Express instead of CE. It's also free but offers more possibilities should you ever need to do more with the application.

As for a way to safely produce and consume the records, just make sure that the table has a an Identity field. The system automatically assign a value to that field, and by default, increase its value by one everytime it receives a new row of data.

You are thus assured to have a unique value for each row, and simply have to follow the sequence to read back the rows in the same order that they were inserted.

Along with this, you can have a processed_flag. Also, this can be achieved using SQL Express/MS Access.
