Database Design -MS Access

[kenone]

Hi
I am a bit new in database development field.I want to develop a

database to hold Treasury Bonds details using MS Access.The development

process should be based on an excel spreadsheet that contains Treasury

Bonds records categorized by duration ie 2yrs,5yrs,7yrs and 10yrs .My

concern here is how to design table(s) that will keep all those

records so that they can be well accessible and maintenable.In fact

,am not sure of how many tables should be developed,their

relationships and whether the normalization process should be in

place...Could you please help me in this.
PS.I have attached an excel file with sample data for your

consideration.
