Is JSON schema a computer program?
You may have noticed that the JSON Schema itself is written in JSON. It is data itself, not a computer program. It’s just a declarative format for “describing the structure of other data”. This is both its strength and its weakness (which it shares with other similar schema languages).
Is a JSON schema valid?
Both representations are equally valid, though one is clearly more formal than the other. The design of a record will largely depend on its intended use within the application, so there’s no right or wrong answer here. However, when an application says “give me a JSON record for a person”, it’s important to know exactly how that record should be organized. For example, we need to know what fields are expected, and how the values are represented. That’s where JSON Schema comes in. The following JSON Schema fragment describes how the second example above is structured. Don’t worry too much about the details for now. They are explained in subsequent chapters.

Some basic concepts
The first thing you need to know is that Power Automate communicates with the various systems using APIs. These are like a restaurant menu. You pick the food you want, and it’s provided to you. But to work, they need to talk the same “language,” and that’s where JSON comes.
JSON Schema
As mentioned before, JSON has a structure that can transport data between services. But it’s important that the data that arrives at the destination is something that you expect and can use.
Final thoughts
JSON Schemas are super powerful and will help Power Automate to know what data to expect. It’s also a good way for you to define that if the data is not in the format you want, the data is invalid, and you won’t even parse it.
JSON
JSON stands for JavaScript Object Notation. It is a lightweight data-interchange format. It is easy for humans to read and write. It is easy for machines to parse and generate.
JSON in databases
One of the big advantages of document databases such as MongoDB, Couchbase, DocumentDB, Elasticsearch, etc., besides their distributed horizontal scalability, is that you can leverage the flexibility and easy evolution of JSON documents.
Representation of nested structures in Entity Relationship Diagrams
The novel added-value provided by Hackolade Studio is its ability to represent nested structures inside an Entity-Relationship Diagram. In a way, we have bent and stretched the theory of ERDs to accommodate a user-friendly view of JSON document structures in ERDs.
