Which type of compression in DB2 reduces the size of data by eliminating redundant information?

  • Adaptive Compression
  • Column Compression
  • Dictionary Compression
  • Row Compression
Dictionary Compression is a compression technique in DB2 that reduces the size of data by eliminating redundant information using a dictionary. It identifies repeating patterns within data and replaces them with shorter tokens or references, thereby reducing the overall storage space required. This compression technique is particularly effective for datasets with repetitive data patterns, leading to significant storage savings and improved query performance.
