About this Gig
Do you have a project or app idea, or do you want to migrate your data from Excel/CSV files into a well-structured SQL Server database with organized tables?
I will transform your business requirements into a professional Entity-Relationship Diagram (ERD) and a production-ready Microsoft SQL Server database schema.
A successful system relies on a solid data foundation. Poor structure causes duplicate records and slow queries. I specialize exclusively in Microsoft SQL Server to deliver clean, normalized, and enterprise-ready solutions.
What You Will Get:
- Visual ERD Diagram (Conceptual & Logical)
- Complete T-SQL DDL Script (CREATE TABLE, Keys, Constraints, Indexes)
- Full Normalization (1NF to 3NF) for integrity
- Sample Mock Data Script (INSERT statements)
- Stored Procedures, Views & Triggers (Standard/Premium)
- Detailed Schema Documentation & Data Dictionary
Technologies Used:
- Microsoft SQL Server
- T-SQL (Transact-SQL)
- SSMS, Lucidchart, draw.io
Why Choose Me?
- Clean, well-commented, and tested T-SQL code
- Focus on scalability and query performance
- Fast delivery and reliable support

FAQ
What information do you need from me to get started?
Please provide a brief description of your business requirements, the entities/data you want to track, and any existing Excel/CSV files or sketches you have. If you already have business rules or constraints, sharing them will help ensure the design fits your exact needs.
Which database management systems (DBMS) do you support?
I specialize in Microsoft SQL Server, but I can also deliver standard ANSI SQL scripts and ERD schemas compatible with MySQL, PostgreSQL, or Oracle upon request.
In what format will I receive the final deliverables?
You will receive the ERD diagram in high-resolution formats (PDF / PNG) along with the editable source file. For the database schema, you will get clean, executable .sql script files containing all table definitions (CREATE TABLE), keys, and constraints.
Can you transform my unstructured Excel or CSV data into relational tables?
Yes, absolutely. I can analyze your Excel sheets, eliminate data redundancy using normalization principles (1NF to 3NF), structure them into relational tables with primary and foreign keys, and provide scripts to import the data into SQL Server.
What if I need changes or revisions after the delivery?
Revisions are included in the packages to ensure complete satisfaction. You can request adjustments to relationships, table attributes, or data types to make sure the schema aligns 100% with your application logic.
