Question

Define Cartesian product joints ..​

Answer 1

Answer:

A cartesion join , also know as cartesion product , is a join of every row of one table to every row of another table . For example if table A has 100 rows and is joined with B , which has 1000 rows , a cartesion joint will result in 100,000 rows

Answer 2

Until the tables in a query are joined to one another, MS access will not know which records are associated with which , so it displays every combination of record table between the tables. therefore , if each tables have five records in it ,the query's result will contain 25 records (5×5). This result set of every possible combination is called cross product or Cartesian product..
