But iteration over the same objects with two range variables forming nested loops (outer and inner) might prevent query execution within a reasonable response time. In this way, static nested classes can always interact with other parts of the program too and increase reusability. As a follow-up of this blog post I would like to get a little bit deeper with a more specific example that I had to solve last year : filtering on a nested field like the e-mail address of a SharePoint Person column.

Our final Spring Data MongoDB example project will look like below image. Im not able to map the nested objects to my form fields. An object-relational database (ORD), or object-relational database management system (ORDBMS), is a database management system (DBMS) similar to a relational database, but with an object-oriented database model: objects, classes and inheritance are directly supported in database schemas and in the query language. The nested type is a specialised version of the object datatype that allows arrays of objects to be indexed in a way that they can be queried independently of each other. The most basic rule is that the AND operation is prioritized before the OR operation. The outer call handles the array of the variable JSON, the inner call handles the objects.
