Microsoft Office dominates the business world and seems to be the defacto standard for word processed documents and spreadsheets.
I have had considerable experience with Word and Excel and have previously given training courses on both as well as providing technical support to end users. Daily functions such as document layout, mail merge, multi-worksheet spreadsheets etc pose no problem.
Whilst not a big fan of PowerPoint presentations, I am competant at creating them if need be.
I have considerable Access experience and am highly proficient at database design. I have built applications based on Access and have also used it as a tool to massage data and generate reports.
