We are familiar with the basic operations of databases and database tables. Now let's take a look at how to operate multiple tables. Multi-Table operations Multiple tables may exist in a database, which are associated with each other. We will continue to use the previous example. The preceding table contains basic information about an employee, such as name, gender, date of birth, and place of birth.

, and the returned substrings are in an array. Split can use regular expressions or plain text as delimiters. Try this: >> "Ruby". Split (//)=> ["R", "U", "B", "Y"]Converts the content of a text-based configuration file into Ruby's data structure. >> line = "First_name=matt;last_name=damon;country=usa"=> "First_name=matt;last_name=damon;country=usa">> record = Line.split (/=|;/)=> ["First_Name", "Matt",
