Question at position 48 Indexes generally slow down access speed in most RDBMS.TrueFalse

BlackTom AI · Accepted Answer

Consider the statement and what indexes do in relational databases. 
Option 1: 'True' — This would claim that indexes generally slow down access speed. In reality, indexes are designed to speed up data retrieval by allowing the database to locate rows without scanning the entire table. While there is some overhead on writes (inserts, updates, deletes) to maintain the index, read operations often become faster, especially for large tables or selective queries. So this option is misleading because it describes a situation opposite to the common purpose of indexes. 
Option 2: 'False' — This correctly reflects the typical role of indexes. By organizing data in a way that supports efficient search paths (like B-trees or hash indexes), the DBMS can jump directly to the relevant pages rather than scanning many rows, reducing I/O and latency for lookup queries. The caveat is that performance gains depend on proper index design and query patterns; if an index is not useful for a given query, or if too many unnecessary indexes exist, there can be overhead, but the general rule is that indexes speed up access. 
Summary of the contrast: the statement as written claims a slowdown that contradicts the primary purpose of indexing, whereas the truthful understanding is that indexing accelerates data access under typical use cases. The potential overhead is context-specific and about write operations, not the general read-access speed the question addresses. Remember that the benefit of indexing is most evident for selective queries and large datasets, where full table scans would be costly. 
Thus, option 2 ('False') correctly aligns with how indexes function in most RDBMS scenarios. The first option misstates the fundamental effect of indexing and could mislead learners about when and how indexes are beneficial.
