My tasks are develop the new report file that access to oracle database, SQL coding to retrieve the data, fix the bug in existed report and deploy it to the real server.
By the way, fixing on other work is harder than develop the new one. One reason is there are no required standard of report development. I can say that I allowed to produce it anyway if it can fruit the correct result and I think previous report developers done with the same principle. That why I need to figure the pattern and methods of each report while fixing it.
