There are many differences between Oracle and Access. First,
you need to know that Oracle and Access are both relational
database engines. Oracle is sold by Oracle Corporation and
Access is sold by Microsoft. The biggest differences between
the two are the size and number of users each supports.
Oracle is a scalable enterprise database engine that
supports from one to many (tens to hundreds of thousands) of
simultaneous users. Access on the other hand is most
commonly used as a single-user database but since the
release of Access 97, can be augmented with Visual Basic
code and can easily support 100+ simultaneous users (Top
limit of 200 users). Oracle can support very large databases
(Tens of Terabytes in size or larger), while Access is
designed for much smaller databases in the 1 to 2 gigabyte
size range.
