Metaspex Tools in C++: A Complete Framework for High-Performance Backend Development

Metaspex

Metaspex is an integrated development framework based on C++, designed to simplify building enterprise-grade backend applications using high-level data modeling systems that provide:

• High performance thanks to native C++ and zero-cost abstractions

• Reliable data models (ontologies) that automatically enforce relationships without SQL

• High scalability across both vertical and horizontal dimensions

• Strong built-in security, embedded within the framework, eliminating the need for external security layers

1. Ontologies: Powerful Predefined Data Models

Every Metaspex project includes a domain-specific ontology (enhanced data model). Ready-made business components are available, such as:

• Security with users, organizations, affiliations, etc.

• time series for Finance, monitoring, Internet of Things.

• ISO-Compliant addresses.

• HTML5-compliant positions.

Ready-made and extensible microservices such as:

• Single sign-on

• Survey (creation questionnaires and gathering answers).

• Internet of Things Devices management platform

• Messaging (Slack-like).

These ontologies define one-to-many, dynamic links, merging, and map directly to C++ code, providing programmatic control without writing SQL manually.

2. SQL-Free Referencing – Built-in Referential Integrity

When you delete an entity (e.g., a post), all associated information (likes, replies, reposts) are automatically deleted, thanks to internal referential modeling—no need for SQL triggers or foreign key definitions.

Key points:

• The generated code compiles with GCC 12 to 15 or Clang 20 into compact binary modules that can be embedded directly in Apache or Nginx.

• Binary code can run from a small footprint Raspberry Pi Zero 2 ($15) to multiple 128-core backends in any public cloud.

• Referential logic is more efficient than traditional garbage collection (GC) or reference counting, and safely handles cyclic references.

3. Flexible NoSQL Integration

The choice of databases is defined in a configuration file. At run time, the compiled application can link to NoSQL databases such as Couchbase, MongoDB, or CouchDB, without code modification.

This allows:

• Implementing the same binary with different databases

• Maintaining referential integrity across NoSQL documents

• Decoupling application logic from storage logic

4. Layered Built-in Security

To accept a Web service call, the backend performs 15 validation steps:

1. Check the session ID

2. Confirm the existence of the requested service

3. Validate the user’s identity and active status

4. Verify the community cookie

5. Check the licensing constraints

6. Confirm user permissions

7. Validate the final JSON structure

8. etc.

These security layers are automatically generated based on the ontology model and enforced through Metaspex’s core libraries.

5. Performance & Scalability

• Calling a Web service on a Raspberry Pi takes just a few milliseconds of real time, allowing thousands of transactions per second.

• Sub-millisecond Web services can be run on larger machines, such as the ones found in the public cloud.

• Native C++ code with compile-time optimizations means no runtime penalties or performance compromises.

• Supports vertical and horizontal scaling for both application and storage.

• Customizability & Deployment Flexibility

• Ontologies can define custom dialects and modify storage rules based on tenant or customer.

• Supports client-specific data model extensions without duplicating binaries.

• Can run offline, via CLI, or as an HTTP server module in Apache/Nginx.

Development Workflow with Metaspex

1. Design your data model (ontology): Define entities, relations, and service interactions.

2. Compile using C++: Use GCC or Clang to turn the model into native binary modules.

3. Choose deployment mode: Build for standalone servers or embed in Apache/Nginx.

4. Select your NoSQL backend: Set your target database in a config file—no code changes needed. Not even a recompile.

5. Security is included: No need for writing manual access control or authentication code.

6. Deploy your service: Start your executable and connect to the backend—API-ready.

Conclusion

Metaspex enables you to build enterprise-grade backend systems in C++ using enhanced data models (ontologies), eliminating the need for SQL, ORM layers, and manual data linking.

Its strengths include:

• High engineering productivity

• Expressive power beyond current data modeling techniques

• Extreme performance

• Built-in referential integrity

• Integrated NoSQL support

• Powerful, automatic security

• Flexibility in deployment and customization

It’s a powerful solution for institutions needing fast, reliable, and scalable backend systems—leveraging modern C++ in a declarative and maintainable way.
