Hell there,

It seems like I cannot run cds "deploy --to sqlite" in my Visual Studio.
I get this error: "bash: cds: command not found"
Can you please help?

Thank you for nice session!.
I have a query, Since Odata is standard, and from its metadata we can interact with Odata, is there any metadata or any other way by which we understand non-Odata Rest (or Http) API structures or action, to interact with?

@qmacro Is oData used to transport large amount of data in ETL process?

Problem with SAP world is that they are very engrossed in looking at what SAP brings. I mean who uses REST and ODATA in today's world. People use graphql. You don't want to implement REST or ODATA ever.
