Chapter 10, Problem 4RQ
Explanation of Solution
List of transaction properties:
The transaction process has the list of properties in each individual transaction. The transaction must display these properties for consistent state. They are:
- Atomicity
- Consistency
- Isolation
- Durability
These above four transactions are referred as ACID test. The other additional transaction property is “Serializability”.
Explanation of transaction properties:
Atomicity:
- This property requires all part of the transaction (SQL commands) must be completed. Otherwise, the transaction is aborted. \
- For example: if the transaction T2 has three SQL commands, all three commands must successfully complete in the transaction. If not it is considered as inconsistent state. Hence, the atomicity property ensures the consistent state of the transaction.
Consistency:
- The property indicates the permanence of
database consistency. If the transaction is completed, the database will move one consistent state to another consistent state.
Isolation:
- This property is used for database transaction and the data item is accessed but one transaction cannot be accessed by any other transactions until the first one ends...

Suppose that the two Rank methods below are added to the Skip List class on Blackboard.
public int Rank(T item)
Returns the rank of the given item.
public T Rank(int i)
Returns the item with the given rank i.
Requirements
1. Describe in a separate Design Document what additional data is needed and how that data is used to
support an expected time complexity of O(log n) for each of the Rank methods. Show as well that the
methods Insert and Remove can efficiently maintain this data as items are inserted and removed. (7
marks)
2. Re-implement the methods Insert and Remove of the Skip List class to maintain the augmented data in
expected O(log n) time. Using the Contains method, ensure that added items are distinct. (6 marks)
3. Implement the two Rank methods. (8 marks)
4. Test your new methods thoroughly. Include your test cases and results in a Test Document. (4 marks)
