Gen Modernization Guide

Gen is a computer-aided software engineering (CASE) tool and application development environment. It generates code in languages like Java, C, and COBOL from a 4GL programming language, automating much of the application development process.

Gen is a tool set designed to automate application development. It provides a 4GL language and generates code, making it more than just a simple application or system.

Organizations that require rapid application development, particularly for mainframe environments, benefit from Gen. Industries with complex systems and a need for maintainable code, such as banking, insurance, and government, are good candidates.

A company should consider Gen when they need to generate applications for multiple platforms, including z/OS, UNIX, and Windows .NET, and want to use a model-driven approach to development. It is particularly useful when needing to maintain and evolve large, complex systems.

Alternatives to Gen include other CASE tools and code generation platforms such as CA Plex, Progress OpenEdge, and OutSystems. These tools offer similar capabilities in terms of application development and code generation.

Gen runs on z/OS, UNIX, and Windows .NET. For z/OS, it typically runs in an LPAR and is dependent on the z/OS operating system. Specific subsystems may be required depending on the generated code and application architecture.

Gen requires a compatible operating system (z/OS, UNIX, Windows .NET) and sufficient resources to run the development environment and generated applications. Specific database systems or middleware may be needed depending on the application requirements.

Gen uses a 4GL programming language for defining application logic. The code generator then translates this into languages like Java, C, and COBOL. The generated code interacts with databases and other systems based on the application design.

Gen's architecture includes components such as the Encyclopedia (a repository for application models), the Generator (which produces code), and various tools for modeling and testing. These components communicate through defined interfaces and APIs.

Gen exposes APIs for integration with other systems. These APIs can be used to automate tasks, extend functionality, and integrate with other development tools. The specific API types and methods depend on the Gen configuration and version.

Gen helps organizations reduce the time and cost associated with application development by automating code generation. It also improves application maintainability and reduces errors through its model-driven approach.

By automating code generation, Gen allows developers to focus on higher-level design and business logic. This can lead to faster time-to-market for new applications and reduced development costs.

Gen integrates with enterprise ecosystems through its support for various programming languages, database systems, and middleware. It can also be integrated with other development tools and platforms through its APIs.

Gen's licensing model is typically subscription-based, with costs depending on the number of developers and the features required. Total cost of ownership includes licensing fees, training, and ongoing maintenance.

Gen supports authentication methods such as LDAP and Active Directory for user management. It uses an access control model to restrict access to resources based on user roles and permissions.

Gen uses encryption to protect sensitive data both in transit and at rest. Specific encryption algorithms and protocols depend on the Gen configuration and the underlying systems.

Gen provides audit logging capabilities to track user activity and system events. These logs can be used to monitor security and compliance.

Gen employs an access control model, likely Role-Based Access Control (RBAC), to manage user permissions and access to different functionalities and resources within the system.

Gen is typically deployed on-premise, particularly in mainframe environments. Implementation requires technical expertise in application development, code generation, and the target platforms (z/OS, UNIX, Windows .NET).

Ongoing operational requirements include monitoring system performance, maintaining the Gen environment, and managing user access. Common implementation challenges include integrating Gen with existing systems and ensuring code quality.

Administrative interfaces for Gen include both command-line interfaces (CLI) and graphical user interfaces (GUI). User management is handled through these interfaces, allowing administrators to create and manage user accounts and permissions.

Gen provides monitoring and logging capabilities to track system performance and identify potential issues. These logs can be used to troubleshoot problems and ensure the system is running smoothly.
