Query regarding access to data (information / it resources) between sez and dta

Hello. I have a question regarding accessing company's business information (data) between its SEZ and DTA accounts. I will put my question in a form of an example here: Suppose, a company is holding two accounts i.e. SEZ and DTA. Employees working from SEZ are registered as employees of SEZ account, and employees working from DTA are registered as employees of DTA account. Company has its all information processing assets like Data Centre, etc. in its SEZ account. Now, the question is that whether employees who are registered in DTA account can access the business information (data centre, etc.), which is in its SEZ? Since there are no proper instructions available on IT related queries on SEZ India website, I am putting this under this discussion forum. Request if anyone can throw light on this area. Thanks.
