2 Architecture
Architectural Foundations for Governed Multi-Tenant Systems.
ZNize Platform is a runtime architecture designed around isolation, composability,
and governed coordination. It defines structural execution boundaries that enable
independent tenants to operate within a unified system.
Tenant as the Fundamental Execution Unit
The tenant is the primary architectural boundary.
Each tenant defines:
- An isolated domain data space
- An independent execution context
- A discrete transaction boundary
- A separate lifecycle
No tenant holds structural privilege over another. Tenant equality is a core invariant.
Isolation is enforced at the session, persistence, and transaction layers.
Domain-Centric Execution Core
At the center of the platform is a model-driven execution engine based on JPA domain entities.
Architectural characteristics:
- Entities define state authority
- Transactions define state transition boundaries
- Versioning enforces optimistic concurrency
- Integrity constraints are enforced within domain scope
The runtime does not treat data as passive records.
Business objects execute within managed transactional contexts that guarantee
consistency and determinism.
State mutation is governed, not implied.
Structured Transaction Governance
All business operations execute inside controlled transaction scopes.
The architecture enforces:
- Versioned optimistic locking
- Deterministic state transitions
- Conflict detection before commit
- Domain integrity validation
Transaction governance is foundational for cross-tenant coordination without data replication.
Consistency is preserved through structured execution, not eventual propagation.
Logical View Projection Model
The user interface layer is a runtime projection of domain state.
The platform introduces a logical view abstraction that:
- Derives interface structures from domain and logic
- Binds dynamically to client environments
- Evolves based on interaction state
The UI is not constructed as static templates detached from domain logic.
It is a runtime projection of the model.
Presentation and execution are structurally aligned.
Modular Composition Graph
Capabilities are introduced through modules.
Architecturally:
- Modules define domain extensions
- Modules register services and UI components
- Modules contribute resources and configuration
- Runtime assembles module graph dynamically
The system is extended through controlled module composition.
Configurable Tenant Type Model
Tenant types are defined as structured module assembly configuration.
A tenant type:
- Specifies available modules
- Defines permitted capability boundaries
- Establishes structural governance
Individual tenants instantiate from a type and may enable permitted subsets.
Standardization occurs at configuration level — not through code duplication.
Hierarchical Site and Resource Resolution
Site composition follows a hierarchical model.
Architectural resolution order:
- Site-level resources
- Parent site resources
- Module resources
- Core platform resources
Overrides are resolved deterministically without resource replication.
Internationalization and customization operate through layered resolution rather than duplication.
Coordinated Cross-Tenant Interaction Model
Cross-tenant collaboration is structured as coordinated state transitions.
Key architectural rules:
- Tenants never directly access another tenant’s persistence layer
- Each tenant updates only its domain-authorized segment
- State changes are coordinated via controlled transaction mechanisms
- Synchronization is governed — not replicated
Collaboration occurs without dissolving isolation boundaries.
The architecture supports enterprise ecosystems while preserving independence.
Automation Aligned with Architectural Abstractions
Automation operates against the logical view model rather than browser implementation details.
Architecturally:
- Automation APIs mirror logical view abstractions
- Tests interact with semantic components
- Validation occurs at execution model level
This ensures regression resilience independent of presentation-layer changes.
Automation reflects architecture, not markup.
Architectural Summary
ZNize Platform is architected around:
- Tenant-bound isolation
- Domain-governed execution
- Transactional consistency
- Logical view projection
- Modular composition
- Hierarchical resource resolution
- Coordinated multi-tenant interaction
It is a governed runtime architecture designed for structured enterprise ecosystems.
