Approaching Omnis again scares me, too much to learn?

[Das Goravani]

Hello All, 

I am RE approaching Omnis with a view to becoming a developer/consultant to businesses. 

I am completely expert with Omnis and the native database it provides, but don’t know SQL or anything else, I only know Omnis. I don’t know any other language at all.  I go back to 86 but haven’t done anything for ten years.  

It’s scary enough to have to learn SQL and how to connect to databases.  But all the stuff you guys and gals discuss here and on the other forum scares me.  How did you all learn all about Java and Jason and Restful etc etc.  How do you keep it straight in your heads? 

My real question is this:  If I could learn SQL and how to setup and maintain backends and the connectivity, is that enough to be a consultant today?  I imagine right away the next point is that businesses will want phone access apps, tablet apps, to access their databases and then I’d be looking at Javascript which I don’t know. 

At age 57 and reapproaching, I wonder how much time it takes to learn these things and begin consulting. 

Are all these fancy other things smaller than Omnis learning itself?  I sure hope so.  It took a good while to learn Omnis.  I’m very good at Omnis but only Omnis Native.  Don’t yet know what a Schema is, but I can do notation to control anything, I can do complex interfaces and handle complex data.  Just dont know anything else.  Do any businesses still go for using the Native Datafile?  With that I’m ready already. 

One reason I want to learn SQL is to earn more.  The businesses for which the Native datafile is appropriate are smaller and poorer.  I believe you can charge more to the SQL requiring businesses.  Comments?

Is the "Lone Developer" still possible?   You all seem to be in teams. 

Just scared badly.   Any help appreciated.
