Customer Requirements

VISA was looking for data analyst services for the Czech branch of a significant multinational bank for smoother payment card portfolio migration. The bank had two basic requirements – to obtain support for the business department from the bank core systems data collected in data warehouse and to design and create regular reporting of the payment card portfolio. In both cases the bank knew that the source of data is spread and undocumented databases, hence the ability of fast orientation in database scheme was a necessary condition for the project.


The delivery stretched for 7 months and included a regular cooperation with the client bank, several dozen individual data analyses were processed and delivered for the business, marketing, and IT departments. Also, the system of regular reports of payment cards portfolio was designed and created, separately for credit and debit cards. The solution was adopted by the bank. An integral part of the solution were also SQL scripts for easy preparation of monthly data for individual reports.
