We want to develop a small application that pulls data from a 11gR2 database. It is likely using MS Access as the user interface and the total # of users around 5 (to start). I know Oracle has free ODBC driver but it requires installing the bloated Oracle Client and the configuration of TNS name is sometimes clunky. So we want to explore alternatives.
Any recommendation of 3rd party ODBC driver (for WIndows both x86 and x64)? DataDirect/Progress has wire protocol it seems many are using it. I am not sure how exactly it is licensed but it seems based on the processors on the Oracle server. Is it cost effective for us? Any other alternatives?
