What is Meta Data in Salesforce?

Hi Suraj,

Metadata literally means data about data. There are different types of metadata, but when it comes to our scalable, metadata platform, we’re talking about the structure of your Salesforce org

Most applications manipulate data, which is often stored in a database. Typically this data is information such as Account details or Contact information. However, you can consider the source code for the application itself as data that provides the information on how your application looks, feels, and functions. You can refer to this information as metadata.

Where as Data is a collection of facts, such as numbers, words, measurements, observations or even just descriptions of things.

In software programming, if you create a class and save its instances to a database, that would be called persisting DATA

The members of the class and their datatypes would be called metadata.

Hoping this information may help you:

Thanks
