FAQ
Which database systems do you work with?
I work with MySQL. Please share your MySQL version so I can make sure the scripts are compatible.
Can you create a database from scratch?
Yes. Standard includes up to 3 tables, and Premium includes up to 6 linked tables. I create the structure, keys, relationships, and sample data based on your requirements.
What do you need to start?
Please provide your requirements and expected results. For an existing database, also send the table structure, relevant SQL queries, and sample data.
Can you create stored procedures or functions?
Yes. One MySQL stored procedure or function is available as an extra for $10. Please contact me first to confirm its purpose and complexity.
What will I receive?
You will receive tested SQL files with comments. Depending on your package, these include database creation scripts, sample data, custom queries, and documentation.
Do you install database servers or connect databases to websites?
The packages cover database design and SQL scripts. Server installation, hosting, and website integration are outside the package scope.
Can you guarantee that my query will run faster?
Performance improvements depend on the query, indexes, data, and server environment. I can review potential improvements, but I cannot guarantee a specific speed increase in advance.
What do revisions include?
Revisions cover adjustments within the original requirements. New tables, queries, or additional features may require an extra or a custom offer.
