This approach targets specific columns known for their uniqueness, such as email addresses or account numbers. Meanwhile, fuzzy matching employs algorithms such as the Levenshtein distance to identify near-duplicates that might contain minor discrepancies or typing mistakes.

By generating distinctive hash values for every record and contrasting them, hashing assists in pinpointing duplicates with matching hashes. Machine learning models can be developed to detect consistent characteristics of duplicate records.

The deduplication process aims at eliminating or consolidating redundant records while ensuring crucial information is retained intact. Even though automated processes are useful, manual scrutiny becomes essential when handling complex cases like similar but not exactly alike duplications.

In maintaining high standards of data quality within CRM systems, several automated measures are typically employed.

  • Combining datasets from disparate sources
  • Flagging up duplicate instances
  • Performing checks on uniqueness which helps guarantee that there are no repetitions of particular fields like email IDs throughout the database.

Handling Missing Values

Ensuring the quality and dependability of a dataset necessitates meticulous attention to missing values during the data cleaning process. Opting to remove entries with absent information is one way to address this issue. It might lead to substantial loss of valuable insights. Alternatively, replacing missing data by extrapolating from existing observations could compromise the authenticity of the entire dataset.
