Database Development

The Foundation of Every Reliable Application

A well-designed database is the backbone of any serious software system. At Dev Team Solutions, we have been working with Microsoft SQL Server for over 25 years, and database development remains one of our strongest capabilities. From initial schema design through to ongoing performance tuning, we handle the full lifecycle.

Our database work underpins everything else we do, from enterprise websites serving millions of requests to job board platforms managing hundreds of thousands of records. When clients like Network Rail and RNIB rely on our systems, the database layer has to be rock-solid.

What We Deliver

Database Design and Architecture

Good database design starts before a single table is created. We work with your team to understand the data model, relationships, access patterns, and growth projections. The result is a schema that performs well from day one and scales as your organisation grows.

We follow established normalisation principles where appropriate, and we are pragmatic about denormalisation when performance demands it. Every decision is grounded in practical experience, not textbook theory alone.

Performance Tuning and Optimisation

Slow queries and database bottlenecks can cripple an application. We have extensive experience diagnosing and resolving performance issues, including:

• Query optimisation — rewriting inefficient SQL and reviewing execution plans
• Index strategy — designing and maintaining indexes that match your actual workload
• Resource contention — identifying and resolving locking, blocking, and deadlock issues
• Capacity planning — ensuring your database infrastructure can handle projected growth

We regularly work with databases that support high-traffic web applications, so we understand the patterns that cause problems at scale and how to avoid them.

Stored Procedure Development

For complex business logic that benefits from running close to the data, we develop well-structured stored procedures in T-SQL. Our code is documented, version-controlled, and written with maintainability in mind.

Data Migration

Moving data between systems is rarely straightforward. We plan and execute migrations using SQL Server Integration Services (SSIS) and custom tooling, with thorough validation at every stage. Whether you are consolidating legacy systems, moving to Azure SQL, or integrating a new data source, we manage the process carefully to minimise risk and downtime.

Reporting and Business Intelligence

Data is only valuable if you can make sense of it. We build reporting solutions using SQL Server Reporting Services (SSRS) and integrate with broader business intelligence workflows. Dashboards, scheduled reports, and ad-hoc query tools give your team the visibility they need.

Azure SQL and Cloud Databases

For organisations moving to the cloud, we offer Azure SQL expertise. We handle migrations from on-premises SQL Server, configure appropriate service tiers, and set up high availability and disaster recovery to meet your business continuity requirements.

Our Experience

Over 25 years, we have designed and maintained databases for clients across multiple sectors. The common thread is a commitment to doing things properly: clean schemas, efficient queries, sensible indexing, and thorough documentation. Our team in Dolgellau brings that discipline to every engagement, regardless of scale.

If your database needs attention, whether that is a new build, a performance review, or a migration to Azure, get in touch and let us take a look.
