Can a customer's database be accessed by another customer?
This applies to all PaySpace editions.
No. PaySpace is powered by a single instance, multi-tenant architecture, in which all users and applications share a single, common infrastructure i.e. database and code base, but is logically and uniquely separated for each customer.
Authorisation and security policies ensure that each customer’s data is kept separate from that of other customers using a TenantID, which associates each record across multiple tables with an individual tenant.
