Study topics for 94.586 Object-Oriented Design of Real Time Systems... April 2001

The exam will be for one hour, and will have short questions ("what is") and slightly 
longer questions ("explain", or "describe", or "compare") related to understanding 
terminology and concepts.

actor, or (in RoseRT) capsule
protocol between actors
hierarchical state machine, substate, action/activity
inheritance among state machines 
(.....add events/states/transitions, retarget trans, change actions/activities, 
.......NOT change existing nesting or remove events/states/transitions)
system global state (with multiple state machines)
message, signal, synchronous or asynchronous interaction
Use Case, sub-Use Case
Use Case Map: path, start-point, end-point, responsibility, stub
scenario

what is architecture; examples of architecture patterns (client-server, shared memory, 
pipeline, combinations)
server, tiered server, forwarding server
static analysis
global analysis, factors, issues, strategies in the work of Hofmeister et al
conceptual, module and execution architecture in their work
conceptual component, connector, port and role
criteria for concurrency, and why (interface, thread of control, parallel, urgent, 
communications, exclusive in time, add/remove/replace, data management)
criteria for modularity: cohesion (temporal, data, logical, functional...) and coupling 
(common, control, arguments)
how to derive module architecture from conceptual architecture
subsystem and layer, criteria for separation of layers (temporal scope, data scope, "uses" 
services) 
module vs process
schedulability; completion time theorem
rate-monotonic analysis, criterion
utilization

fault recovery mechanisms (logging, checkpoint and rollback)
failure detection mechanisms (logging, heartbeat, predicate checking)
kinds of fault tolerance (full masking, isolation (transaction aborts), recoverable, auto 
recovery, fail safe)
exceptions: examples, handling mechanisms (in-line, separate process)
software features for fault tolerance (predicate checks, handlers, layering, separate 
processes, replication of data and functions, voting, audit processes)
