What should my job title be?

My boss wants to redefine my job and does not want me to be called a Financial yst. Instead he wants me to focus on the implementation of two software packages, Cognos for budgeting, and an additional Excel-add in dashboard that will be linked to operational and ledger files. My focus will be to get us out of Excel-hell and automate all of our spreadsheets. This will be supported by Accounting and IT, but driven and directed by the Finance department as the go-between, so I can't be called Data Base Administrator or anything that would make me sound like an accountant or an IT worker because...well.. I'm not. I will be a "power user".... who helps other people get numbers out of the system. What should I be called?
