The properties of PM cell elements are:

Element Name: listed in the table shown below.

A description of the element

Element Name	Type	Description
i2b2 Workbench	Client Component	Webservice client submits the requests to the PM server components and renders a response XML.
Project Management Server	Server Component	The ONT cell uses the PM cell to authenticate the user. The ONT cell constructs the PM request message and makes a web service call to the PM cell.

JDBC	Query Connector	SQL query used as a connector between the PM System and the metadata DB.
Web Service	Request Connector	SOAP or REST request used to communicate with the external system.

Design Rationale, Constraints

N-tier Architecture
The client-server style depicts the n-tier architecture that separates presentation layer from business logic and data access layer; thus providing for a high degree of portability.
