Please see response inline. I am not an expert, in learning stage, so please
bear with me if I am asking very basic questions.

I do not mind if Drupal can manage data directly. Here the only concern is
performance. While adding data, it should be faster and more importantly,
while seraching one should be able to search quickly (given huge number of

Data is not from 3rd party. Over the period of time, I really hope number of
users will increase.

Skill set is basically comma (",") separated values. Example - PHP, SQL,
Drupal, VoIP, SIP, HTTP etc.
This is the field that will be used during searching of records instead of
using resume just to have improved performance.

The data addition, delete and search are the major operations.
If you can think any other data operations (which I might be missing) ,
really appreciate if you can share.
Is there any way, where I can compress the resume and store as zip file,
when somebody really wants it unzip and give it.
This may be usefull to save memory to great extent.
