Integrate suiteCRM in an open source product

I’m currently a student at Tunisia’s National school of computer science and trying to integrate your suiteCRM in a platform I’m cuurently working on and hopefully releasing it as an Open source product soon.
Can you please help me with a few questions I have about SuiteCRM.
1- Is SuiteCRM 100% Open source ?
2- Is it possible to integrate SuiteCRM in my open source product and which licenses must I include ?
