Database Software

I am looking to create a compound polygon with multiple lines and arcs using the geodetic co-ordinate system...in an effort to resemble an irregular shape like a US state for example. I did look at the compound polygon shown in the link below which shows a compound polygon that resembles an ice cream cone but i need to have something complex.

http://docs.oracle.com/cd/B28359_01/appdev.111/b28400/sdo_objrelschema.htm#i1005726

In the example below, i don't understand exactly what SDO_ELEM_INFO = (1,1005,2, 1,2,1, 5,2,2)... means how is it calculated?

Also this example just had four co-ordinates, SDO_ORDINATE_ARRAY(6,10, 10,1, 14,10, 10,14, 6,10)

what if i have more lines and circular arcs...can anyone help give a complex example of inserting a compound polygon with multiple lines and arcs and help understand what each and every attribute represents in the example?

Thanks in advance
