This project centers on architecting a brand-new SQL Server database that will handle high-volume transactional data from day one. I already have the application requirements and data flows mapped out; what’s missing is a robust, well-normalized schema that scales smoothly and enforces data integrity without sacrificing performance. Here’s what the finished work should cover: • Conceptual and logical data models (ERD) based on my specifications • A fully scripted physical schema in T-SQL—tables, primary/foreign keys, indexes, constraints, default values, and sequences where appropriate • A transaction-friendly indexing strategy plus partitioning guidance if it becomes beneficial • Sample stored procedures or parameterized queries that illustrate best-practice CRUD operations • Brief documentation explaining design decisions, assumptions, and any future scaling considerations You’re free to use SSMS, Azure Data Studio, or your preferred IDE, as long as the scripts run cleanly on SQL Server 2019 (or later). I’ll test the deliverables in a staging environment; acceptance is complete when all scripts execute without error and the design meets the documented requirements. If clarification is needed on the data flow, naming conventions, or compliance constraints, I’m available and responsive—let’s create a rock-solid foundation for this application.

Hi there! I’m a data/DB architect with 18+ years’ experience, 4.9★ rating, and strong repeat clients. I specialize in SQL Server 2019/2022, high‑throughput OLTP design, and performance tuning—delivering production‑ready schemas, 3NF/BCNF normalization, and bulletproof referential integrity without sacrificing speed. How I’ll deliver (focused & technical): Requirements → Canonical model: Confirm entities, cardinalities, SLAs; define domains, collations, and naming conventions. Conceptual & logical modeling: ERD with keys, constraints, and state transitions; audit & history strategy (temporal/CDC as needed). Physical schema (T‑SQL): Schemas, tables, PK/FKs, CHECK/DEFAULT, IDENTITY/SEQUENCE, computed columns, rowversion for optimistic concurrency. Indexing & performance: Clustered index strategy, covering/filtered indexes with INCLUDE, SARGability, statistics; Query Store presets. Partition‑readiness: Range partitioning design (e.g., by date or tenant), partition function/scheme, filegroups, compression—enabled when volume justifies. CRUD procedures & patterns: Idempotent, transaction‑safe procs with XACT_STATE(), TRY…CATCH, XACT_ABORT ON, parameterization, consistent error codes. Integrity & reliability: FK actions, data quality rules, NOT NULL rigor, invariants via CHECK; isolation level guidance to balance throughput vs. contention. Security & governance: Role‑based access, least privilege, schema ownership boundaries, PII masking suggestions.

Hi, I have been designing database schemas from scratch by first understanding the platform and integration requirements. I create detailed ER diagrams and translate them into normalized schemas that ensure scalability, integrity, and performance. As an Azure practitioner, I work with SSMS, SQL Server, Azure Data Factory, and Microsoft Azure. My experience includes building schemas with proper primary/foreign keys, indexes, constraints, and partitioning strategies for high-volume data. I also implement stored procedures, parameterized queries, and CRUD operations to make databases efficient and application-ready. For the past year, I’ve successfully designed and managed schemas for multiple projects, along with documentation to explain assumptions, design choices, and future scaling considerations. I’d love to share my experience and expertise to help you build a solid and optimized foundation for your application. Regards, Suryansh
