An example might be a table of salespeople and a separate table of company cars. Each salesperson can only have one car, or be related to the one car in the database. A one-to-many relationship occurs when a record in one table has many related records in a second table. An example might be a table of salespeople and clients. Each salesperson may have several clients. A many-to-many relationship occurs when records in one table have many related records in a second table, and the records in the second table have many related records in the first table. An example might be a clients table and a products table. Clients may buy more than one product, and products are sold to more than one client.
