EB2 filling code/occupation?

[jsvo]

Little background on my Education and work experience in the order of accomplishment

Diploma in Mechanical engineering (3 years) India

Bachelor of Arts (3 years) India

• 1 yr as a customer executive in Campaign Management Unit (telnet, Avaya, SCR software tools) in India
  
• Then 4yrs as Assistant Managers for Software Testing in India
  

Master in Business Administration with concentration in Information systems (core courses related to database) from USA.

• Working from past 2 years as Database analyst/Data Conversion specialist (USA) salary 55K
  
• Few days ago promoted as Senior Database analyst/Data Conversion specialist (USA) 63K.
  

My company a Michigan based American company filed for my H1B as a Database administrator last year and now is willing to file for my EB2 visa.

With the USA masters and also current job (senior database) did require masters so I think I am eligible for EB2. But when I looked up the www.onetonline.org there is only Database administrator which says bachelors is need nothing that talks about Masters.

1. Do I need to apply in a different code?
   
2. What would be the salary range for that code (to file as EB2)?
   
3. Or Am I ok by just using DBA code and mentioning that I’m Sr.DBA with that salary?
