Multi-Tenant Software Architecture with Segmented Database Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-tenant data architecture systems face challenges in supporting diverse database schemas and column structures across multiple tenants, making it inefficient to use a single database schema and leading to scalability issues when the number of tenants increases.
Innovation Solution
A software application instance supports multiple tenants by identifying the tenant-specific context, obtaining a service object, and using a data access object to perform operations on separate databases, isolating data access logic from the business logic layer and utilizing an inversion of control container for dependency injection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single database schema is used to support multiple tenants, then device complexity is reduced, but manufacturing precision deteriorates because different tenants require dissimilar tables and column structures
Solution Approach 1:
The patent segments the database system by providing each tenant with a separate database instance rather than using a single shared database. This segmentation allows each tenant to have their own schema, tables, and column structures tailored to their specific requirements, thereby maintaining data structure accuracy while managing complexity through modular isolation.
Solution Approach 2:
The patent applies local quality by allowing each tenant database to have customized schemas and data structures specific to that tenant's needs. Instead of enforcing a uniform schema across all tenants, each tenant can define their own tables, columns, and data relationships, ensuring that the data structure accurately reflects the local requirements of each organization.
2Manufacturing precision
If a separate software application is provided for each tenant, then manufacturing precision is improved by providing dedicated functionality, but device complexity increases and scalability deteriorates
Solution Approach 1:
The patent merges multiple tenant-specific software applications into a single multi-tenant platform. By consolidating the software infrastructure while maintaining separate databases for each tenant, the system achieves the functionality precision of dedicated applications without the complexity and scalability issues of multiple separate systems. The single software instance can serve multiple tenants through standardized interfaces and data access patterns.
3Device complexity
If a single software application services multiple tenants, then device complexity is reduced, but productivity deteriorates due to the inability to efficiently support diverse data requirements
Solution Approach 1:
The patent segments the data storage layer by providing separate databases for each tenant while keeping the software application unified. This segmentation enables efficient data operations for each tenant by allowing independent database optimization and management, thereby improving productivity without significantly increasing system complexity.
Solution Approach 2:
The patent introduces an intermediary layer (the multi-tenant software platform) that mediates between the user and the underlying database structures. This intermediary handles the complexity of managing multiple diverse databases, providing a unified interface that maintains productivity by abstracting away the underlying data diversity while preserving efficient data access patterns.
Data Source
AI summary
One embodiment of the present invention relates to a system that enables a single software application instance to support multiple tenants, wherein each tenant is associated with a separate database. First, the software application instance receives an input, wherein the input requires an operation to be performed on a database of one of the supported tenants. Next, the software application instance identifies the tenant with which the input is associated. The software application instance then obtains a context associated with the tenant. From the context, the software application instance obtains a service object. Finally, the software application invokes a method provided by the service object's class. This enables a data access object, which is encapsulated within the service object, to perform the operation on the database.
