Enterprise Application Design Patterns

The Enterprise Application Design Patterns course is dedicated to the foundational and advanced patterns essential for the development of robust corporate applications. Participants will explore design principles, typical architectures, and best practices needed for constructing scalable and maintainable enterprise applications. The course begins by introducing core design principles, including the multi-layered approach to structuring applications, common data presentation strategies using the MVC (Model-View-Controller) framework, and organizing business logic for maximum efficiency.

This training is highly practical, targeting developers, senior developers, and junior architects, who will gain insight into object-relational mapping techniques, approaches to separate and organize business logic, and patterns for structuring applications into logical layers. The course covers key patterns for enterprise development, such as Dependency Injection, Repository, and Unit of Work, equipping attendees to design and implement the building blocks of enterprise systems effectively.

The course includes modules on the following:

- Introduction to Layered Architecture: Learn about dividing applications into logical layers to ensure separation of concerns, maintainability, and flexibility. Understand common approaches to creating the presentation, business, and data layers.
- Business Logic Patterns: Explore essential patterns for managing business logic and organizing processes. Learn how to handle complex workflows and transactions across multiple system boundaries.
- Object-Relational Mapping (ORM): In-depth discussion on ORM, its challenges, and how it supports application scalability by abstracting data access and simplifying CRUD operations.
- Model-View-Controller (MVC) Framework: Understand how to use MVC to organize data presentation in web environments, allowing for the effective separation of user interface and business logic.
- Parallel Processing: Techniques for handling parallel processing and managing multiple transactions in distributed systems to ensure efficient load balancing and resource utilization.
- Distributed Object Access: Patterns for creating interfaces for distributed object access, such as Service Locator, Proxy, and Remote Facade, which enable efficient interaction with remote services.

Upon completing this course, participants will be able to:

• Implement a multi-layered architecture for enterprise applications.
• Structure and optimize business logic for efficient processing and maintainability.
• Utilize MVC frameworks to separate data presentation and improve web application performance.
• Design effective ORM implementations for managing complex data relationships.
• Apply distributed object access patterns to create scalable, distributed applications.
• Integrate these patterns into modern architectures like microservices, ensuring scalability, reusability, and adaptability to evolving business requirements.

This course is structured with approximately 50% theory and 50% practical labs. Participants will engage in hands-on exercises to solidify their understanding of each pattern, allowing them to build solutions for real-world enterprise challenges.

After the training, the attendees will be able to:

• Divide enterprise applications into layers
• Know the basic approaches to organizing the business logic
• Know in detail the mechanism of object-relational mapping
• Organize the presentation of data on the web using an MVC system (model-view-controller)
• Understand the principle of parallel processing of tasks involving several system transactions
• Design the interface of distributed object access
