Migrate to SQL

Experts,

This is a follow up to a similar question
http://www.experts-exchange.com/Microsoft/Development/MS_Access/Q_28352469.html

1. If migrating to SQL then all the forms, reports, modules, queries, relationships will be lost?  Meaning they do not convert over and will need to be rebuilt in SQL?  

2. To me, "migrate" means everything moves over and if not, then the tables are only a very small part of the big picture and I dont see a lot of time being saved with any migration to SQL from Access.  You basically have to start over is how I see it.

3. Wouldnt the programmers need to spend a lot of time developing the interface?  Meaning that if the IT dept says "yeah well put someone on it" but in reality they dont plan to spend much time developing it then its probably fair to say the interface will not be well done and getting bugs fixed etc etc will be like pulliing teeth.   My pt is that the developer can not approach the job carelessly and needs to devote many hours even after the initial interface.

4. If the tables are in SQL then its common to build the interface in SQL as well?  

Thank you for the help...

Not quite...

SQL Server holds your data.  Just think of it as a new back-end.

Your Front End (Access) links to the SQL Tables.... with very little change needed to your form/report/query interface.

There are a few things needed - one that comes to mind is that all of your recordset and action query code will need the dbSeeChanges option added.  

But for the most part, your FE will remain the same.

Oh I see what you are saying.  
I failed to mention that IT does not want to use Access at all.  

does this change something?

Changes everything.

I would double/triple check... that they are not allowing Access even as a user interface.

If it is allowed, changing to a SQL Back-end is very smooth.

If they are absolutely positively not allowing it, then the changes will be significant, including:

1.  A complete redesign and rewrite of ALL of your forms, reports, code and queries.

2.  The learning curve involved in adjusting to a totally different platform such as .Net for the user interface.

I was under the assumption that SQL is also a FE.  

What other FE's are there?   .NET is one I can think of.

If we use a different FE other than Access then we are are completely at the mercy of IT is how I see it.  I dont want that as it will take too much time to wait on them.

SQL is really just the data, and maybe queries/stored procedures to manipulate it to some degree.

It is NOT a user interface.  That is where Access ideally comes back into play, or if that is totally out of the question it would be .Net or something else.

Possible the easiest to transition to if necessary would be VB.Net (but it would not be a straight-forward copy/paste or import, it would be a redesign/rewrite)


EDIT:

Missed your last posts too :)

I am sure they dont want to use Access.  They manipulated IT into saying Access is not an approved software.  It makes no sense because we were already using Access.  What I am dealing with is someone that is above me and is extremely inefficient at what they do and desires to have their name as "author" on something.
