DBA for SQL Server for 9 years, DBA for DB2 2 years experience, Python experience 4 years. I have done some work with python library pymssql, automating some tasks for SQL Server not yet for DB2, no problem for me to get in deeper, you could see my profile to see my Python experience, I have done a game with Python and a PostgreSQL work. I have read your request and have some questions, windows/linux systems with no Intenet access, How are you planning install Python ?, Why Security is a issue, do you prefer a normal user with limited privileges or a special superuser?, load file has a header record that must be skipped. (has a fixed length ?),the DB tables will reside in a given (depends on the implementation) schema within their database. (Will need to create, or are created, or use our own DDL?) Date Discrepancy,The script will be used for 2 different tables.(What is the table definition for all cases?), need more clear ideas in this subject. I'am thinking that I could do this job in 5 five days, it is appropiate for you ?. I'am open to adjust my time and my cost. https://www.freelancer.com/u/lemarin68
