My main use case for SQL Server 2014 Express is in SQL that I'm using in my project because I am receiving data in large quantities. SQL is very fast and reads the data very quickly and processes it rapidly, so it is not dependent on SQL to slowly process; it processes quickly.
For example, I use SQL Server 2014 Express to store bot execution logs, transaction status, and intermediate data generated by the automation process. The bot reads and writes data in real-time to track success, failure, and retries. It is also used for temporary data storage, audit tracking, and reporting for small workloads where enterprise scale databases are not required.
It works well for storing bot logs, staging data, and small transaction workloads.
