Topic #: 2

[All Architecture-Specialist-11 Questions]

Which of the below matches the most to Core Module Pattern - ECS with Local Replica Pattern...

H... is needed if data is coming from MULTIPLE external systems. IS will decide which driver to use depending on the data.

A... 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

G... tries to fetch data from local cache entity, if not there, get single entry from the external 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

FSame 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

E... Entity is exposed as read-only and API is available to centralize business logic for entity creation/update

C... 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

B... 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.
p 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

ISame 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)

D... 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)

The Core Module Pattern - ECS with Local Replica Pattern is like a secret handshake for the tech elite. If you don't know it, you might as well just give up now.

I think the answer is option C. It just makes the most sense in terms of the pattern description.

The Core Module Pattern - ECS with Local Replica Pattern is definitely the way to go. It's like a Swiss Army knife for your application!

I feel like the Core Module Pattern focuses on modularity, but I need to double-check how that interacts with ECS.

If I remember correctly, the Local Replica Pattern is about data consistency, but I'm a bit confused on how that ties into the Core Module.

I remember practicing a similar question where we had to match patterns, but I can't recall the specifics about ECS.

I think the Core Module Pattern relates to how we structure our code, but I'm not entirely sure how it connects with the Local Replica Pattern.

Okay, I know I covered this material in class. Time to recall the definitions and see which one best matches the Core Module Pattern - ECS with Local Replica Pattern. Gotta stay calm and think it through.

Ugh, design patterns can be so confusing sometimes. I'll just try to remember the main components of each and see if I can find any overlaps. Fingers crossed!

Hmm, this seems like a tricky one. I'll need to carefully consider the key characteristics of the Core Module Pattern and how they relate to the ECS with Local Replica Pattern. Gotta stay focused!

I think I've seen this pattern before, but I'm not totally sure how to approach it. I'll need to review my notes on ECS and local replica patterns.
