JSON-Relational Duality Views.
A JSON-relational duality view exposes data stored in relational tables as JSON documents. The documents are materialized — generated on demand, not stored as such. Duality views give your data both a conceptual and an operational duality: it’s organized both relationally and hierarchically. You can base different duality views on data stored in one or more of the same tables, providing different JSON hierarchies over the same, shared data.
This means that applications can access (create, query, modify) the same data as a set of JSON documents or as a set of related tables and columns, and both approaches can be employed at the same time.
Yes, that is correct. With a JSON-relational duality view, applications can choose to interact with the data either as relational tables or as JSON documents, depending on their needs. This duality view allows the same data to be accessed and manipulated in multiple ways, without the need for redundant storage or complex transformations.
By providing multiple hierarchies over the same data, duality views enable applications to easily and efficiently retrieve the data they need, without having to perform complex joins or other operations. This can be especially useful for applications that need to work with complex or nested data structures.
Overall, the JSON-relational duality view provides a flexible and efficient way to work with data, allowing applications to choose the approach that best fits their needs.
In database management, a duality view is a conceptual model that allows data to be represented both relationally and hierarchically at the same time. This means that the same data can be accessed and manipulated using either a relational model (such as SQL) or a hierarchical model (such as JSON).
Duality views enable applications to work with data in a more flexible and efficient way, as they can choose the representation that best suits their needs.
By providing out-of-the-box REST APIs for duality views, ORDS makes it easy to expose data to web and mobile applications, without the need for custom coding or complex integrations. This can help to accelerate development and simplify data management, while also providing a more flexible and efficient way to work with data.
Overall, REST enabling a duality view with ORDS can provide a powerful and streamlined way to work with data, enabling developers to easily build and integrate applications that leverage the power of both relational and hierarchical data representations.
