OutSystems Architecture Specialist (OutSystems 11) : Architecture-Specialist-11

What is the Architecture Blueprint?

• A. Above is the answer
• B. Is the end result of Architecture Design Process. At this point you should add dependencies between the Modules.

_BL module is for

• A. Isolated Business Logic (Actions), to manage complexity, composition or to have its own 'ifecycle.
• B. Reusable Core Services with public entities, actions, and blocks.
• C. A BL becomes a Calculation Engine if it performs complex calculations, (e.g. an invoice calculation engine or an insurance simulator). Engines are usually subject to versions.
• D. Logic to Synchronize data in CS's with an external system. Isolating this logic makes the CS completely system agnostic and it's easier to decouple or replace the external system.
• E. Technical wrapper to expose an API to External consumers, keeping core services system agnostic and supporting multiple versions of the API.

Which of the below matches the most to Library Module Pattern - Connector Pattern...

• A. ... tries to fetch data from local cache entity, if not there, get single entry from the external n system. Cache only that record (read-through caching) Use when whole database too big or costly to synchronize. Integration only touches a small portion of the database. Avoid if access to lists of data is needed up front
• B. Same as ECS with local replica but API module is provided. So any changes to the external system can notify OS, which OS then gets update from the ERP system (subscription system)
• C. ... Entity is exposed as read-only and API is available to centralize business logic for entity creation/update
• D. ... is a pattern with two modules, a connector module that can be used to encapsulate an ) external API with the input/output structures and a wrapper module to expose the normalized API to the consumers.
• E. ... Entity is not in Outsystems but in an external ERP system. IS just makes remote call to p external system/database. No data is being kept inside OS. Data retrieval may not be optimized as it needs to traverse two different systems to get the information back. Con: Integration API must support all use cases
• F. ... caches only summary data that is frequently lister, joined or searched. Full detail for a single entry is fetched directly from external system. Use when whole database too big or costly to synchronize. Details are only required for single entities (not lists)
• G. Same as Base ECS pattern, but have a local replica. Store data to serve as a local cache. Pro: Leverage Entity Use, Simpler Integration API. Con: Less impact on source system
• H. ... a wrapper used to contain the logic, actions and data that will expose code that is inside of external library or to inspect external database and import the data structures so they can be used as entities inside of OS
• I. Same as ECS with local replica but synchronization logic is separated. Pro: Code independence. Consumers of CS is not affected by Sync. Sync can orchestrate several CS
• J. ... is needed if data is coming from MULTIPLE external systems. IS will decide which driver to use depending on the data.

Which of the below matches the most to Core Module Pattern - ECS with Publish/Subscribe through ESB...

• A. Same as ECS with local replica but API module is provided. So any changes to the external system can notify OS, which OS then gets update from the ERP system (subscription system)
• B. ... Entity is not in Outsystems but in an external ERP system. IS just makes remote call to p. external system/database. No data is being kept inside OS. Data retrieval may not be optimized as it needs to traverse two different systems to get the information back. Con: Integration API must support all use cases
• C. ... Entity is exposed as read-only and API is available to centralize business logic for entity creation/update
• D. ... is a pattern with two modules, a connector module that can be used to encapsulate an O external API with the input/output structures and a wrapper module to expose the normalized API to the consumers.
• E. ... a wrapper used to contain the logic, actions and data that will expose code that is inside of O external library or to inspect external database and import the data structures so they can be used as entities inside of OS
• F. Same as Base ECS pattern, but have a local replica. Store data to serve as a local cache. Pro: Leverage Entity Use, Simpler Integration API. Con: Less impact on source system
• G. Same as ECS with direct integration, but through an Enterprise Service Bus
• H. Same as ECS with local replica but synchronization logic is separated. Pro: Code independence. Consumers of CS is not affected by Sync. Sync can orchestrate several CS
• I. ... is needed if data is coming from MULTIPLE external systems. IS will decide which driver to use depending on the data.
• J. ... tries to fetch data from local cache entity, if not there, get single entry from the external p system. Cache only that record (read-through caching) Use when whole database too big or costly to synchronize. Integration only touches a small portion of the database. Avoid if access to lists of data is needed up front

What is done in the Organize part of the Architecture Design Process?

• A. Concepts are assembled into Modules
• B. Concepts are added to the layers of the Architecture Canvas
• C. Concepts are disclosed to the Architecture team
