Which of the below matches the most to Core Module Pattern - Core Entity Pattern.

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.

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

... 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

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

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

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)

... 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
