a.

It increases data access costs.

b.

It eliminates data access costs completely.

c.

It reduces data access costs as it learns about raw data files.

d.

It incurs a fixed data access cost for each query.

Posted under Big Data Computing

Answer: (c).It reduces data access costs as it learns about raw data files. Explanation:The NoDB project's adaptive loading approach reduces data access costs as it learns about raw data files over time. As more queries are processed, the system gains knowledge about how data reside in raw files and can reduce the cost of accessing that data in the future.
