Special Topic:
Dynamically Constructing ORDA Queries with a JSON-Based Query Framework – Juan Carlos Perez

In the realm of database management systems, the ability to dynamically construct and execute queries is paramount for flexibility and efficiency. Thankfully, using ORDA in 4D applications gives us a powerful approach to optimizing the search of complicated data structures.

In this meeting, Juan Carlos Perez will introduce a framework designed to leverage ORDA queries through a JSON-based query storage mechanism.

The demo will explore a framework that allows the definition of complex queries as JSON strings, encapsulating both query descriptions and parameters within a single object. This approach not only facilitates the creation of a query catalog specific to any database, but also allows developers to execute these queries programmatically by parsing the JSON strings into executable query objects. The framework outlines methods for storing, retrieving, and parsing these JSON query objects, seamlessly integrating with existing ORDA functionalities.
