bme, thanks for your answer. I am just trying to sense how you guys work in real Oracle development and how you use tools that is confusing me little bit. About that, otn.oracle.com.. have already done that... I don't have any problem in technical aspects programming part as i have many years of experience on that.. it just the TOOLS i am trying to learn. Ooh ! one correction: You will need only 10 DAYS to learn Oracle if you want Sajha.com to teach you. You don't know the ability of some SAJHA visitors... dude:)
