Question

Advantages & Disadvantages of tree-based indexing:

a) Faster search, Limited storage overhead
b) Increased storage, Slower search efficiency
c) Enhanced data retrieval, Limited data organization
d) Reduced memory usage, Complex data retrieval

Answer 1

Tree-based indexing offers faster search efficiency and enhanced data retrieval but comes with increased storage overhead and the potential for complex data retrieval if the tree structure becomes unbalanced.

Step-by-step explanation:

The question focuses on the advantages and disadvantages of tree-based indexing, a method often used in databases to improve data retrieval times. Tree-based indexing structures, like B-trees and binary search trees, are designed to keep the data sorted and to decrease the time complexity of search operations.

Advantages of Tree-Based Indexing:

• Faster search efficiency due to the structured format that allows for binary search capabilities within the tree.
• Enhanced data retrieval as complex queries can be handled efficiently due to the organized nature of the tree structure which leads to faster search results within large datasets.

Disadvantages of Tree-Based Indexing:

• Increased storage overhead compared to flat file systems because the indexing structure itself consumes space.
• Complex data retrieval processes can occur if the tree becomes unbalanced, leading to degraded performance in search operations.
