4D v11 SQL has extended the capabilities of hierarchical list items to allow storage of Object-like structures. The same hierarchical list item may have values of different types; i.e. numerical, string or boolean. In other words, you can associate a dictionary with each list item.
Using the commands SET LIST ITEM PARAMETER and GET LIST ITEM PARAMETER, you can store Objects
using native 4D v11 SQL Commands.
Using the new hierarchical lists architecture in 4D v11 SQL, you can now tag lists, data, name pair values, etc. without the use of plug-ins. With 4D v11 SQL native commands you can store different types of data in Objects that can be used to manage parameter lists, store preferences, manage sessions, send a record to a different process, etc.
Objects can add flexibility and allow you to improve the way your code is designed and executed.
