FAQ
What information do you need from me to get started?
To provide the best results, I need a detailed description of your project requirements, any specific business logic, and your preferred database engine (MySQL, SQL Server, etc.). If you have a rough sketch of the tables or an existing ERD, please share that as well.
Can you create a login system with different user roles (Admin, User, etc.)?
Yes! I can design the database schema to support multiple user roles. This includes creating the necessary tables for users, roles, and permissions, ensuring your system's data is organized and secure.
What if I need changes after delivery?
No problem! Your satisfaction is my priority. Every package includes a specific number of revisions. If you need minor adjustments or find any issues after delivery, I will be happy to fix them within the revision period.
Can you redesign or fix an existing database?
Absolutely. If you have a messy or slow database, I can perform Normalization, fix relationships, and optimize your SQL queries to improve performance and data integrity.
Can you help with university or semester database projects?
Absolutely! I can assist with academic and semester database projects from scratch, including creating perfect ERD diagrams, mapping relational schemas, writing assignment queries, and providing clean technical documentation.
