I planing to buy Alvarez AD60CE Dreadnought Electro Acoustic Guitar - Pau Ferro/Indian Laurel Fretboard for learning finger style playing techniques, will this guitar will serve my purpose ?
Flamenco and classical guitar is usually played on nylon strings. The tension is different and the material is quite different. It depends on what you mean by "flamenco techniques". If you mean finger style arpeggiating chords, a lot of acoustic guitar players finger pick. Even some electric players play finger style (Joe Pass for example). However, I think you will have a hard time developing tremolo techniques and some other strumming techniques on the steel string acoustic. Using your nails on the steel strings with force and speed may cause breakage. If you try to learn finger style on any guitar it will be a specific finger style modified for that guitar. The touch is so much different that you cannot, in my experience, just transfer skills from one to another. But you can try, it may work for you.
You can learn finger style playing techniques in any guitar, but to sound the way you want and to execute the technique correctly you need at least a guitar with nylon strings.
In any case, transporting knowledge from one guitar to another won't be difficult, but the touch and the space between the strings is different.
Also keep in mind that you cannot change the type of strings for which the guitar is prepared.
