FAQ
What do you need from me to design the database?
Please provide a description of your system, the data you need to store, the main users or processes involved, and any existing requirements or diagrams you already have.
Will I receive an ER diagram?
Yes. All packages that include Schema Diagram (ERD) will include a visual representation of the database entities, attributes, relationships and cardinalities.
Will you also provide the SQL schema?
Yes. I can provide SQL scripts including tables, primary keys, foreign keys, relationships, constraints and other required database structures.
Can you normalize an existing database?
Yes. I can analyze an existing schema, identify structural issues or redundancy, and redesign it using appropriate normalization principles.
Can you help me choose the right database technology?
Yes. I can review your requirements and recommend an appropriate relational database platform based on the size, structure and needs of your project.
Can you modify or improve an existing ERD or database schema?
Yes. I can review an existing ER diagram or schema, correct modeling problems, improve relationships and constraints, and provide an updated design.
