1. Sequential Selection: Selects data one record at a time, in order of appearance.
2. Random Selection: Picks records randomly from the data file.
3. Cyclic Selection: Cycles through the records in the data file repeatedly.
4. Correlation Selection: Allows selecting specific records based on a specified correlation value.
