hierarchical nametree conventions, see Nametree below.
An End–Item is an MDB item located at the lowest hierarchical level (leaf
or terminal node), and hence cannot be further decomposed.
Mission
The performance of a coherent set of investigation or operations in space
to achieve space programme goals. A single mission may require more
than one flight, and more than one mission may be accomplished on a
single flight.
Mission Database (MDB)
This is the central repository for all HW / SW configuration information
about Columbus Flight Elements, Payloads and associated Ground Support Equipment. Access to the MDB is controlled and managed by MPS.
N
Nametree
Hierarchical (tree) structure within the MDB which portrays the hierarchical decomposition of Columbus Flight Configurations into systems, subsystems, equipment, etc. The topmost node of the nametree (called the root
node) designates the Flight Configuration, whereas terminal nodes (leaf
nodes) represent the items that cannot (or need not) be further decomposed,
i.e. the so–called end–items.
Each MDB object is thus identifiable by a pathname indicating the succession of nodes to be traversed to reach that particular item in the Nametree.
Node
any component of a network or tree structure.
(e.g. LAN node, nametree node)
O
Operating System (OS)
The system software that controls the computer and its parts, performing
the basic tasks such as allocating memory, and allowing computer components to communicate.
P
Parent
In a hierarchical structure, denotes an immediate ancestor of a given component.
Pathname
see Nametree
Q
R
Reconfiguration
A procedure which changes the status of used hardware and software items
Report
In the context of this document, a report may be defined as any human–readable description of one or more MDB items. It is an assorted collection
of information usually presented to the user in form of a table or itemized
list (tabular format).
