FAQ
What information do you need to start?
Please provide the SQL query, database platform, relevant table structures and, if available, execution plans or performance details.
Do you need direct access to my database?
Not necessarily. In many cases I can work with SQL code, table definitions, execution plans and performance information provided by you.
Which database platforms do you work with?
I mainly work with SQL Server, Oracle, PostgreSQL and Teradata. Please contact me before ordering if you use another platform.
Does the service include optimization of my entire database?
No. Each package covers the queries and tables defined in its scope. Larger environments require a custom assessment.
Can you guarantee a specific performance improvement?
No specific improvement percentage can be guaranteed because performance depends on data volume, infrastructure, workload, indexes and database configuration.
