Understanding database to adopt it in our website

Hello!

I really love this plugin, it provides the things that I needed for my website, thank you for this. But we wanted to extend it’s usage that’s why we needed to understand how the plugin work in database.

Now, what we wanted to do is when we added a post with a category of JOB, that post will be added in the FORM MANAGER PLUGIN drop down. But the problem is this is how it save items in database:

a:4: {s:7:”options”;a:9: {

i:0;s:13:”Administrator”;
i:1;s:15:”Admin Assistant”;
i:2;s:5:”Nurse”;
i:3;s:7:”Midwife”;
i:4;s:14:”PHP Programmer”;
i:5;s:11:”Radiologist”;
i:6;s:34:”Sales and Marketing Representative”;
i:7;s:17:”Technical Support”;
i:8;s:23:”Web and Graphics Artist”;

}

s:4:”size”;
s:0:””;
s:9:”list_type”;
s:6:”select”;
s:7:”default”;
s:10:”–Choose–“;}

we can’t figure out what’s the meaning of a,i and s . Hope you can help me understand it. Thanks a lot! ??
