SQL Server
Microsoft's enterprise database we work with for .NET and existing systems.
SQL Server is Microsoft's enterprise-grade relational database, widely used inside businesses that run on Microsoft and .NET technology. It stores and serves structured data reliably at scale, with strong tooling, security and reporting. HDC works with SQL Server when a client already runs on it, connecting websites to live stock, inventory or order data held in existing systems, rather than forcing a migration.
Where it shines
- Enterprise-grade reliability, security and performance, trusted by large organisations
- Integrates seamlessly with .NET and the wider Microsoft and Azure ecosystem
- Excellent tooling for management, reporting and analytics out of the box
- Strong support for live business data, stock, inventory, orders, ERP systems
- Mature, well-documented and backed by Microsoft's long-term support
- Free Express and Developer editions exist for smaller or non-production use
Trade-offs to weigh
- Licensing for production editions can be costly compared with open-source options
- Heaviest fit for the Microsoft world, less natural outside .NET projects
- Overkill for a simple marketing site that has no existing data to connect to
What SQL Server is
SQL Server is Microsoft’s enterprise relational database management system, first released in 1989 and now a cornerstone of business IT in organisations that run on Microsoft technology. Like other relational databases, it stores structured information in related tables, but it’s built and tuned for the demands of business systems, with strong security, performance and management tooling baked in.
Its real strength is its place in the Microsoft ecosystem. SQL Server integrates tightly with .NET, Windows Server and Azure, and ships with mature tools for administration, reporting and analytics. That makes it the default home for critical business data, order systems, inventory, ERP and line-of-business applications, inside a great many established companies.
How HDC uses SQL Server
We work with SQL Server mainly where a client already depends on it, rather than introducing it to new projects. In practice that means:
- Connecting a client’s website to live data held in SQL Server, stock levels, pricing, order status, inventory, through a secure API.
- Reading from existing Microsoft and .NET systems so the public site reflects the real, current state of the business.
- Building or extending data-driven features for clients whose teams and infrastructure are firmly in the Microsoft world.
- Keeping the public website fast and static on top, refreshing from the database on a schedule, so visitors never wait on a back-office system.
- Respecting the existing source of truth, we integrate with it, we don’t rip it out.
Why we apply it
The reason to work with SQL Server is almost always continuity. Many established businesses have years of critical data and tooling built around it, and that investment is worth protecting. When a website needs to show real information, what’s actually in stock, the current price, an order’s status, the data already lives in SQL Server, and the sensible move is to connect to it rather than duplicate or replace it.
That approach adds value without disruption. The client gets a modern, fast website that tells the truth about their business, while their proven internal systems keep running exactly as they do today.
How SQL Server fits our stack
SQL Server is the data layer we connect to when a client’s world is Microsoft-shaped. It pairs naturally with .NET systems and the wider Microsoft and Azure DevOps tooling that often surrounds them. We bridge it to a fast public site built with Astro and hosted on Cloudflare, pulling live data through a secure API so the front end stays quick and the back office stays untouched. For new builds outside the Microsoft ecosystem, we’d more often choose an open-source database like PostgreSQL, but where SQL Server already holds the data, it’s exactly the right thing to integrate with.
When SQL Server isn’t the right tool
We’re pragmatic about it. For a new project with no existing Microsoft systems, the licensing cost and ecosystem weight rarely justify choosing SQL Server over an open-source option like PostgreSQL. For a WordPress site, MySQL is the natural fit. And for a simple marketing site with no live data to display, no database of this kind is needed at all. SQL Server is the right tool in one clear situation: when a client already runs on it, and the job is to connect their website to the real data they depend on.
Worked example
A website that shows live stock from the system you already run
Picture a supplier whose stock and pricing live in an existing Microsoft-based system backed by SQL Server, but whose website lists products with no idea of what's actually available. Customers enquire about items that are out of stock, and the team wastes time correcting them. Rather than rebuild the back office, we'd connect the new website to the SQL Server data through a secure API, so the site shows live availability and current pricing pulled straight from the source of truth. The public pages stay fast and static, refreshing from the database on a schedule, while the existing system carries on as normal. The website finally tells the truth about stock. (Illustrative, every build is scoped to your goals.)

What is SQL Server used for?
SQL Server is Microsoft's relational database for storing and serving structured business data. It's common inside organisations running on Microsoft technology, powering everything from internal systems and ERPs to the live stock, order and inventory data behind a business.
Does HDC build new projects on SQL Server?
We usually work with SQL Server where a client already runs on it, connecting their website to existing Microsoft systems. For brand-new builds we more often choose open-source options like PostgreSQL, unless the client's environment or team is firmly in the Microsoft world.
Can you connect my website to data in SQL Server?
Yes, that's one of the most valuable things we do with it. We can connect a fast modern website to live data held in SQL Server, so it shows real stock levels, pricing or order status pulled straight from your existing system, without replacing what already works.
Why does HDC use SQL Server?
Because many established businesses already store their critical data in it. Working with SQL Server lets us connect a client's website to that real, live data and integrate cleanly with their .NET systems, adding value without forcing a disruptive migration.
Is SQL Server expensive?
Production licensing can be a significant cost, which is one reason we'd weigh it against open-source databases for a new build. That said, free Express and Developer editions exist, and when a client already licenses SQL Server, using it adds no new database cost at all.
Is SQL Server better than PostgreSQL?
They serve different worlds. SQL Server is the natural fit inside Microsoft and .NET environments, with excellent tooling and integration. PostgreSQL is our go-to open-source choice for new builds. The right answer depends on a client's existing systems and team.
