Question

What are the costs of indexing?

1) Requires more ____
2) Requires ____ to create an index on ____
3) Requires ____ to update the index whenever ____

Answer 1

Indexing has costs such as requiring more memory, time and effort to create, and updates whenever the data changes.

Step-by-step explanation:

Indexing is a process that involves creating an organized structure, like an index, to quickly retrieve data. However, there are some costs associated with indexing:

1. Requires more memory: Indexing adds an additional data structure, which requires more storage space.
2. Requires time and effort to create an index: Building an index involves analysing and organizing the data, which can be time-consuming.
3. Requires updates: Whenever the data changes, the index needs to be updated, adding extra overhead.

For example, in the private sector, wage contracts may be indexed to account for the cost of living, so employees' wages increase with inflation. In the public sector, tax brackets may be indexed, ensuring that people's tax obligations adjust with inflation.
