Essential Questions for a DBA When Requesting a New SQL Server Database

 

Introduction

When planning to host a new SQL Server database, it is essential to provide a Database Administrator (DBA) with detailed and well-structured information. This ensures a smooth deployment, optimal performance, and long-term maintainability. Below are key questions that a DBA will require answers to before provisioning a new SQL Server database.

Why is a New SQL Server Database Needed?

Business Justification and Objectives

  • What is the primary purpose of this database?

  • What business problem will this database solve?

  • Is this database replacing an existing system? If so, why is a new one required?

  • What benefits will this new database provide to the organization?

  • Are there regulatory or compliance reasons for creating this database?

Expected Impact and ROI

  • How will this database improve operations or efficiency?

  • What is the projected Return on Investment (ROI)?

  • What would be the consequences of not creating this database?

What Will the SQL Server Database Be Used For?

Type of Data and Application

  • What type of data will be stored (structured, semi-structured, unstructured)?

  • What are the primary applications that will connect to this database?

  • Will this database be transactional (OLTP) or analytical (OLAP)?

  • Will there be any real-time data processing needs?

  • Are there any integrations with third-party applications?

Security and Compliance Requirements

  • What are the security and access control requirements?

  • What are the data retention and backup policies?

  • Will this database need to comply with regulations such as GDPR, HIPAA, or PCI DSS?

  • Will there be encryption at rest and in transit?

When is the Database Required?

Timeline and Milestones

  • What is the expected go-live date for this database?

  • What are the key milestones leading up to deployment?

  • Is there an urgent business need driving the deadline?

  • Will there be a phased rollout or a big-bang deployment?

Data Migration Considerations

  • Will existing data be migrated to this new database?

  • What is the estimated volume of data that needs to be imported?

  • Are there any downtime constraints for migration?

  • Will there be any need for data transformation or cleansing before migration?

Where Will the SQL Server Database Be Hosted?

Hosting Environment and Infrastructure

  • Will this database be hosted on-premises or in the cloud?

  • If cloud-based, which provider will be used (Azure SQL, AWS RDS, Google Cloud)?

  • What is the anticipated infrastructure size (CPU, RAM, storage requirements)?

  • Will high availability (HA) and disaster recovery (DR) configurations be required?

Network and Access Considerations

  • Will this database be accessed from multiple geographic locations?

  • Are there any specific network security requirements?

  • What type of connectivity (VPN, direct connect, public/private network) is needed?

  • Will there be any firewall or IP whitelisting requirements?

How Will the Database Be Designed, Managed, and Maintained?

Database Design and Development

  • What will be the database schema and indexing strategy?

  • Will there be stored procedures, functions, or triggers?

  • Are there any specific constraints or business rules that need to be enforced?

Performance and Optimization

  • What is the expected number of concurrent users?

  • What is the estimated transaction volume per second?

  • Will there be any need for query optimization or indexing strategies?

  • Are there plans for partitioning large tables?

Backup, Recovery, and Maintenance

  • What are the backup and restore policies?

  • What is the Recovery Point Objective (RPO) and Recovery Time Objective (RTO)?

  • Who will be responsible for ongoing maintenance and monitoring?

  • Will automated maintenance tasks (reindexing, statistics update) be required?

Monitoring and Alerts

  • What performance monitoring tools will be used?

  • Will there be automated alerting for slow queries or downtime?

  • Who should be notified in case of performance degradation or failure?

Conclusion

Providing detailed and well-thought-out answers to these questions will help DBAs deploy and manage a highly optimized SQL Server database. Ensuring that all aspects—business needs, security, performance, and maintenance—are considered in advance will contribute to a smooth implementation and long-term success.
