Multi-Tiered Transaction Model for Deployment Operations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional two-tiered client-server architectures are inefficient for large enterprises due to the tight coupling of business logic, presentation logic, and user interface logic, making it difficult to maintain and update applications, especially in dynamic environments.
Innovation Solution
A multi-tiered architecture is employed, where presentation logic, business logic, and database components are logically separated and moved to dedicated servers, using J2EE standards, allowing for a more flexible and scalable solution with improved deployment services and management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a two-tiered architecture is used, then the system structure is simple, but the coupling between business logic, presentation logic and user interface logic is tight making maintenance and updates difficult
Solution Approach 1:
The patent divides the monolithic application into separate logical layers: presentation layer, business logic layer, and data access layer. Each layer is independent and can be modified without affecting others, resolving the tight coupling problem while maintaining manageable system architecture.
Solution Approach 2:
The patent extracts the business logic from the client-side monolithic application and places it on the server-side. This extraction allows the business logic to be centralized, making it easier to maintain and update without redistributing client applications.
2Adaptability or versatility
If business logic is changed frequently in response to changing business rules, then the system adapts to dynamic environments, but the tight coupling in two-tiered architecture makes client-side code brittle and requires frequent updates
Solution Approach 1:
The patent implements a dynamic architecture where the business logic layer can be modified independently on the server-side. The presentation layer can adapt to different user interfaces through a standardized interface, allowing the system to respond to changing business rules without breaking client-side code.
Solution Approach 2:
The patent introduces a standardized interface as an intermediary between the presentation layer and business logic layer. This interface acts as a contract that allows changes in business logic without affecting the presentation layer, thereby maintaining client-side code stability while enabling frequent business rule updates.
3Ease of manufacture
If presentation logic and business logic are tightly coupled in client applications, then the implementation is straightforward, but changing the user interface requires breaking the business logic
Solution Approach 1:
The patent segments the application into distinct presentation and business logic layers with well-defined interfaces. This segmentation allows the user interface to be changed independently by modifying only the presentation layer, while the business logic remains intact and unchanged.
4Adaptability or versatility
If a multi-tiered architecture is implemented, then flexibility and scalability are improved, but the deployment complexity increases
Solution Approach 1:
The patent creates a universal deployment framework that can handle multiple types of components (presentations, business logic, data access) through a standardized deployment mechanism. This framework provides common operations for deployment, management, and monitoring across all layers, reducing the actual complexity despite the multi-tiered structure.
Data Source
AI summary
A system and method are described for performing deployment operations according to a transaction model. In one embodiment, a request to initiate a transaction to perform a deploy service operation is received. In response to the request, the transaction is initiated at a container. The transaction is then committed to a database if the transaction is successful. The successful transaction reflects the deploy service operation being completed at the container.
