Hello, I'm from Bangladesh and I'm interested to learn oracle myself. I can't spend a penny in institution for learning oracle. I 've little experience on working access. You know the limitations and that's why I'm switching to oracle. I want to build software like inventory Management Systems, Sales & L/C Management Systems, Goods information management software, student management software etc. I know nothing about oracle, even I am not acquainted with oracle developer kit or enterprise edition. Please suggest me some learning materials with link (even if material is in this site, this site's document section is huge) and procedure to finish step by step. Any material related to my target which is available free on the net will be helpful for me. But kindly mention which one needs to be done after which one. Thanks in advance.
