I have been familiar with SAP for almost 16 years. I'm quite comfortable with SAP products, actually.

I have been using this solution for over five years. I use the latest version. 

I've been using SAP ASE for more than a year. 

I have been using the solution for about 30 years.

I've been using this solution for five years. 

We've been using the solution for two years.

The first time I was faced with RDBMS Sybase ASE was in 2005; before that, I worked with Oracle databases. My acquaintance with Sybase ASE was very unique. I worked for a financial institution on a developer position, where my task at that time was to create software that allowed people without strong IT skills to migrate from v12 to v15 in around 160 branches. For this reason, I started to learn the Sybase database and DBA routines before really starting my main task. Since 2005, I have worked very closely with Sybase ASE 12.0 & 12.5 as a developer and later, after migration to version 15.X, as a database administrator. At the same time, I was acting as chief of the relevant department.

I have been using it for the last 20 years.

18 years, with the last four years using it at intervals (app changes and administration).
