Hi @adobeid24 ,
well, there are probably as many variations of how submitted data can be handled as there are integrations and solutions out there.
CRX is just one of them and suitable for Demo and Development purposes. It is a bit like saving your submitted data to a file on the file system. To fetch it again you need to know where it is and what it was called.
CRX is also not a database which means OOTB querying is limited.
You may also have security concerns if PII and sensitive data is stored, Your CRX may not be as secure as some secure data store out there (be it database or other systems).
An RDBMS is probably the better solution and you may be able to use inbuilt features of FDM and Data Sources.
Some solutions would integrate with systems such as SAP, PeopleSoft, what have you. You would then use special APIs and write custom services.
In short: It depends on what you need to do with the data once it is submitted. 🙂
Look around in Experience League - there are articles regarding data submission from Adaptive Forms.
