Concurrency control

The DBA’s responsibilities include physical design, installs, security, backups, and requirements of the database. 7. The trade-offs for concurrency controls are: a. If it’s too strict it can lead to locking the entire database. b. Other measures have low level of concurrency control. 8. Atomic transaction ensures that all the actions on the database are done or none of them are done at all. If none of them are done then the database remains unchanged. It’s important because if ensures that important actions are taken that would otherwise undermine a specific action. For example, overcharging a customer, when they deleted their purchase. 9. A concurrent transaction is when two transactions are being processed against a database at the same time. A simultaneous transaction seems like it is happening at once, but in reality the different transaction is performed on a different line item, and then immediately switched back to the first request. Only one CPU is required for a simultaneous transaction. 11. 12. Lock granularity is the size of the lock. 13. An exclusive lock, locks the item from any other access. No other transaction can read or change the data. A shared lock locks the item from change but not from…

Assignment Instructions: When a detection algorithm determines that a deadlock exists, the system must recover from the deadlock. The most common solution is to roll back one or more transactions to break the deadlock. List the three actions that need to be taken using figure 16.18 to discuss. (Silberschatz, Korth, & Sudarshan, 2001, p.618) A deadlock occurs when a sequence of transactions is waiting for access to data that is being held by a lock in another transaction in the same cycling…

parts. Throughout this production silly things occur that cause the audience to laugh, and I myself find them humorous as well; because of this I would have a difficult time maintaining my composure. An example of where this would occur would be act 2 scene 4, when Dorine is trying to set her plan in motion but is unable to because Valere and Mariane can’t keep their hands off of each other. This is already and awkward scene but it is also very funny, with that combination I would have a very…

People are something Quentin can advise but not control. Quentin even used the abstraction of committing incest with his sister Caddy to pacify the anger from the boys Caddy loves. Quentin keeps reminding himself about “death at the salt licks” to tell himself that Caddy can change. Quentin used the word “death” to signify the manipulation he has on his ideas and the potential of abstractions to collapse under reality(95,102). Salt blocks are used to lure deer and in this context it is something…

Management Theory 1 1 History of the Management Theory The term management must be understood before the management theory can be understood or described. According to Charles Smeby Jr, (2014), the term management “is what enables an organization to achieve its goals, efficiently and effectively, with the necessary staff, equipment, and resources” (p. 29). He further goes on to say that there are four main points of responsibility of management. These include planning, organizing, directing, and…
