SQL Server and SQL Azure offer a superior level of security. If data protection is essential, then migrating to a SQL database solution is the safer choice.

SQL Server boasts robust data integrity safeguards and transaction logs for better data maintenance and recovery.

SQL server gives you the ability to back up your database at any time with scheduled automatic backups and safeguard your data even when the server is in use.

SQL Server's built-in features and triggers give admins insight into who is modifying data and undoing changes.

SQL Server significantly improves performance by only passing requested data and independently completing all operations.

SQL Server is a stronger enterprise-level data storage solution, offering superior performance for larger numbers of users.

Stillwell-Hansen had been reliant on the same core application to manage its sales and service orders since the late 1990s. Once the Access-based platform reached the end of its support lifecycle, the team knew they needed a better, more forward-looking solution to run the business. 

Our Process

Stillwell-Hansen's existing software touched every aspect of the business, so it was crucial that DOOR3 take the needs of a diverse range of users into account. Beyond integrating existing critical functionality, we examined how teams were working outside the application and how that work could be incorporated and streamlined to encourage adoption across the organization.

While Stillwell-Hansen had previously relied on Microsoft Access, DOOR3 updated the platform by moving it to a modern, web-based model. Now, all the company's functions are centralized in a single, intuitive platform that vastly improves visibility and reporting abilities.
