Equivalent to a Row in Excel. A Tab is used to expose an object and its data to the end user through the web interface. A Tab is not necessarily associated with Object all the times (there are different types of tabs). Page layout controls how the fields are arranged in the page. Each Profile has its own Page Layout. Each App has its own tabs (changing App has no impact on Security).2016-08-29_1124 What is metadata? How does it compare to Data? Configuration within Salesforce, including, as an Salesforce Study Materials example, object and field definitions is stored within something called metadata. This is usually entered and configured by the Admin or Consultant. For example, in the above screenshot, “Website ” is a field with field type = URL and label “Website”. These define the field, and hence they are metadata. You can consider the source code for the application itself as data that provides the information on how your application looks, feels, and functions: this is metadata. Another example:, the custom field “Reason Lost” on the opportunity object is defined with metadata, while the opportunity records are data. Metadata is the information about the configuration: we define a field using metadata (field type, length, label…), and this fields will then contain the data.
