We Speak Your Language
Synergy DBL can take your application wherever you want it to go
A Modern Language for Modern Enterprise Applications and Challenges
Synergy DBL is a proven, flexible, and reliable business language that empowers developers to create scalable, extensible applications that meet today’s enterprise demands
Solid Foundation, Continuous Evolution
With its roots in Digital Equipment Corporation’s DIBOL language, DBL has continually evolved to support modern programming paradigms and technologies.
DBL delivers the tools developers need to build, innovate, and future-proof their enterprise solutions.
Choose Your Target
You can create DBL applications that run under the traditional Synergy runtime, the .NET runtime, or both.
Traditional Synergy DBL
The traditional Synergy runtime is a native runtime environment that provides execution and system-level services.
Synergy DBL for .NET
Synergy .NET enables you to create Synergy libraries and applications that target .NET Framework and .NET 6 and higher on Windows and Linux. You can extend your applications by taking advantage of .NET libraries and third-party tools.
Develop and Debug in Visual Studio
Whether you’re developing traditional Synergy or Synergy .NET applications, Synergy DBL’s tight integration with Visual Studio provides access to IntelliSense, Visual Studio wizards and designers, unit testing, performance profiler/instrumentation, the Visual Studio debugger, and much more.
Built-In Database, Optimized File Access
Synergy DBL incorporates a high-performance ISAM (Indexed Sequential Access Method) database, designed for applications that require fast, reliable access to large volumes of data. With native syntax support and robust tooling, Synergy ISAM offers
- A hierarchical indexing structure, enabling efficient key-based access to records.
- Integral resiliency and recovery features, including auto-recovery of corrupt files, selective flushing of I/O writes to disk, and the ability to rebuild in-use ISAM files quickly.
- Maintenance utilities to verify, recover, optimize, and otherwise manage data files.


RDBMS Access
Synergy DBL also enables efficient access to relational database management systems like Oracle, MySQL, and Microsoft SQL Server via Synergex’s SQL Connection product. Use SQL Connection to bring the powerful features of relational databases to your users.
