Transaction Processing in Distributed DBMS - Explore the key concepts of transaction processing systems in distributed database management systems, including their importance, characteristics, and challenges.
We also explore design considerations for transaction processing performance in the front-end side and efficient way of guaranteeing data durability in the back-end side. We evaluate the prototyped system using standard database benchmarks, and experimental results show that adopting the decoupled ...
A transaction is a logical unit of database processing that includes one or more database access operations such as insertion, deletion, modification, and retrieval. Instructions are always atomic in nature i.e. either an instruction executes completely or it does not execute at all. But it is...
With regards to transaction processing in a peer to peer database network, we mainly focus on how to maintain a consistent execution view of concurrent transactions in peers without a global transaction coordinator. Since there is no global transaction coordinator and each peer executes concurrent ...
When a failure occurs during commit processing, automatic recovery consistently resolves the results at all sites involved in the transaction. However, if the remote database is destroyed or re-created before recovery completes, then the entries used to control recovery inDBA_2PC_PENDINGand associated...
Transaction Processing Abstractions Transaction Context Earlier in this chapter, we saw that each transaction has a transaction ID, and that each program that executes a transaction has context information that includes its transaction ID. Thus, the transaction ID is state shared by the programs execut...

DBMS Transaction Management - Learn about transaction management in DBMS, including ACID properties, transaction states, and concurrency control techniques.
A manual example of transaction processing would be that every time you purchased an item, you added the amount paid to a running total. Contrast with "batch processing," which means that you save all receipts in a drawer and add them up at the end of the year for taxes. See two-...
We implement this architecture in Odysseus/DFS, an integration of the Odysseus relational DBMS, that has been being developed at KAIST for over 24 years, with the DFS. Our experiments on transaction processing show that, due to the high-level functionality of Odysseus/DFS, it outperforms Hbase...
