Types of database architectures

A Database Architecture represents the Database Management System’s (DBMS) design (schema). The DBMS architecture makes it easy to understand the components involved in the database system and their relations. The DBMS architecture may vary based on the system on which it runs. Some systems contain both client and server machines whereas some run only on a server machine. Based on the architecture, the system can be classified as centralized, decentralized, or hierarchical.

1 Elaborate on the ACID test in relation to transaction properties.
How can deadlock possibility be influenced by the choice of a transaction boundary?
How does the "wait-die" scheme help manage concurrent transactions?
Transaction management deals with the problems of always keeping the database in a consistent state even when concurrent accesses and failures occur. Isolation requires that each transaction sees a consistent database at all times and that an executing transaction cannot reveal its results to other concurrent transactions before its commitment. ANSWER If two concurrent transactions access a data item that is being updated by one of them, it is not possible to guarantee that the second will read the correct value. Dirty reads and nonrepeatable reads may occur when one transaction can see intermediate results of another transaction before it has been committed.. Given below are two concurrent transactions T1 and T2 whose balances of amount x (balx) were recorded at times t, between t₁ and tg. As shown in the table below: If these two transactions interfere with each other, fill in the table below by selecting from the drop down list the values of balance X (bal,) at specified times…
Q. No. Concurrency Control is a most important element for the proper functioning of a system where two or multiple database transactions that require access to the same data, are executed simultaneously. You have to discuss all issues of concurrent access of data with the help of self-assumed scenarios and data. Note: this question is related from database subject kindly solved it correctly and completly.
How do "serializable transactions" ensure data consistency in concurrent environments?
Briefly describe the strategies for dealing with deadlocks.
Explain the three most prevalent problems with concurrent transaction execution. Explain how you can avoid these issues by using concurrency control.
What is the significance of the "serializability" property in transaction processing?
What is the meaning of “Atomic” with regards to atomic transactions in relational databases? a. A correctly executed transaction is not susceptible to system failures. b. Concurrent execution of transactions does not lead to incorrect results. c. Execution of a transaction does not invalidate the data. d. a) A transaction is either executed completely or not at all. How does taxation handle the issue of spider traps while computing PageRank? a. a) It allows a random surfer to teleport to a random web page with a certain probability. b. It prevents a surfer from going to any web page that is part of a spider trap. c. It repositions a random surfer to the starting web page when it visits a web page that is part of a spider trap. d. None of the above
When you take the bull by the horns and apply an optimistic approach to concurrency control, it's no surprise that transactions can drag their feet and take forever to wrap up. Explain?
Suppose the deferred modification technique is used in a database. a. Is the old-value part of an update log record required any more? Why or why not? b. If old values are not stored in update log records, transaction undo. Is clearly not feasible. How would the redo-phase of recovery have to be modified as a result? C. Deferred modification can be implemented by keeping updated data items in local memory of transactions, and reading data items that have not been updated directly from the database buffer. Suggest how to efficiently implement a data item read, ensuring that a trans action sees its own updates.
