Software And Architecture

Introduction There are scenarios where we have a DTO or a model class that contains a collection of properties and there might be some endpoints that require a subset of them and some other endpoint that might need all of them. Example: Consider a scenario where we need a list of Categories in a dropdown and we have an API that gets all the categories from the static masterdata and need to send to the UI in response to an API call. Problem Statement  We might choose to use a `Map` data type so that we send out the key-value pairs to the database or to choose to build a custom DTO with only the Id, name of the categories. In a longer run, if we opt to use multiple DTO in the source, sooner there will be a very large collection of DTO classes that represent subset of a static data. Solution Rather than ending up with a large number of such DTO classes, we can use a JSON View. This helps us have a single class and control which fields are part of which view.  Example: We can have a dropd
