Each borrower's database has a series of required collection of document needed for the BB works; these collections contains the information related to clouds involved in federation. Below are listed the collection that need to be constructedby federation administrator when a new borrower is included in the federation:

-
datacenters: it contains information about cloud in which borrower has an agreement/contract and that are used in the federated deployment;
-
faInfo: It contains the information related to BNA component for each federated cloud;

An important collection present inside "ManagementDB" database is "SystemInfos", this collection contains the pointer for the module involved in the federation like BNM.
