Fragmentation

Fragmentation

1. Horizontal Fragmentation

   • Horizontal fragmentation divides a relation(table) horizontally into the group of rows to create subsets of tables.

2. Vertical Fragmentation

   • Vertical fragmentation divides a relation(table) vertically into groups of columns to create subsets of tables.

3. Hybrid Fragmentation

   • Hybrid fragmentation can be achieved by performing horizontal and vertical partition together. Mixed fragmentation is group of rows and columns in relation.
