IM/Transaction Processing
[Elective]
Topics:
• Transactions
• Failure and recovery
• Concurrency control
• Interaction of transaction management with storage, especially buffering
Learning Outcomes:
1. Create a transaction by embedding SQL into an application program. [Usage]
2. Explain the concept of implicit commits. [Familiarity]
3. Describe the issues specific to efficient transaction execution. [Familiarity]
4. Explain when and why rollback is needed and how logging assures proper rollback. [Assessment]
5. Explain the effect of different isolation levels on the concurrency control mechanisms. [Assessment]
6. Choose the proper isolation level for implementing a specified transaction protocol. [Assessment]
7. Identify appropriate transaction boundaries in application programs. [Assessment]
IM/Distributed Databases
[Elective]
Topics:
• Distributed DBMS
o Distributed data storage
o Distributed query processing
o Distributed transaction model
o Homogeneous and heterogeneous solutions
o Client-server distributed databases (cross-reference SF/Computational Paradigms)
• Parallel DBMS
o Parallel DBMS architectures: shared memory, shared disk, shared
nothing;
o Speedup and scale-up, e.g., use of the MapReduce processing model (cross-reference
CN/Processing, PD/Parallel Decomposition)
o Data replication and weak consistency models
Learning Outcomes:
1. Explain the techniques used for data fragmentation, replication, and allocation during the distributed
database design process. [Familiarity]
2. Evaluate simple strategies for executing a distributed query to select the strategy that minimizes the amount
of data transfer. [Assessment]
3. Explain how the two-phase commit protocol is used to deal with committing a transaction that accesses
databases stored on multiple nodes. [Familiarity]
4. Describe distributed concurrency control based on the distinguished copy techniques and the voting
method. [Familiarity]
5. Describe the three levels of software in the client-server model. [Familiarity]
