What level of SQL Server expertise do I need for typical business database tasks like customer management and reporting?
For basic customer databases and standard reports, an intermediate-level professional is usually sufficient. They can design proper database structures, write efficient queries, and set up automated reporting. You'll need advanced expertise for complex integrations, performance optimization of large datasets, or enterprise-level security implementations.
How can I tell if a candidate actually knows SQL Server well versus just having it on their resume?
Ask them to walk through a real database problem they've solved, focusing on their troubleshooting process. A skilled professional will discuss specific tools they used, performance metrics they monitored, and trade-offs they considered. They should also ask detailed questions about your data volumes, current performance issues, and business requirements.
Can SQL Server handle both my day-to-day operations and business intelligence needs, or do I need separate systems?
Modern SQL Server can handle both operational databases and business intelligence workloads, especially with features like columnstore indexes and in-memory processing. However, for very large analytical workloads, you might benefit from a separate data warehouse or Azure Synapse Analytics to avoid impacting your operational systems.
How well does SQL Server work with the other business tools we're already using like Salesforce or our accounting software?
SQL Server integrates well with most business applications through various methods including direct database connections, APIs, and ETL tools. It has particularly strong integration with Microsoft tools like Power BI, Dynamics 365, and SharePoint. For third-party systems like Salesforce, integration typically works through ODBC connections, web services, or specialized connector tools.
How long should I expect a typical SQL Server project to take, like setting up a new customer database or migrating from our current system?
A new customer database typically takes 2-4 weeks including design, development, and testing. Database migrations vary widely based on complexity and data volume - simple migrations might take 1-2 weeks while enterprise-level migrations with multiple systems can take 3-6 months. Performance optimization projects usually show results within 1-2 weeks of focused effort.
After my SQL Server database is set up, what kind of ongoing maintenance and support will I need?
Expect regular tasks like monitoring performance, applying security updates, managing backups, and optimizing queries as your data grows. Most businesses need someone to spend 5-10 hours per month on routine maintenance, plus additional time for troubleshooting issues or implementing new features. Critical systems may require more frequent monitoring and faster response times for problems.
