It's not the complexity of the form  that should answer this question, it's
the shape of the data.

It looks as though you are talking about a series of job  master records,
each with multiple resource  records. This immediately sounds "database" to
me. Trying to store this sort of data  in Excel is definitely non-trivial,
while it is bread and butter to a database.

You can create  your forms  in Access, or you can do them in Excel and access
the Access database  from Excel.

(Or you can do the lot in Excel if you wish.)
