In XML data storage, the data is stored in a file which represents an XML Schema of the data. To read the data, you have to pull and open the entire file in memory and use technics like xpath to get the data element you want. In SQL data storage, the data is stored in a database ( usually relational database). To read the data, you simple sent an SQL query to the database. The database management engine analysis the query and get the required data elements you ask for in your query which is finally sent to you as a reply.

XML is a markup language used for structuring and storing data in a hierarchical format, whereas SQL is a programming language used for managing and querying data stored in relational databases. XML is more flexible and self-descriptive but less efficient for complex queries compared to SQL, which offers better performance and scalability for relational data storage and retrieval.

What is the difference between SQL and file based databases?
SQL and "File Based Databases" can't really be compared directly as they refer to two different concepts. SQL is a language for querying databases. "File Based Databases" often refer to data storage that you manage through your own methods, rather than using a language like SQL to query and manipulate the data. For example, MySQL stores its data in files on the hard drive. To store and manipulate the data and its structure, you use SQL queries. MySQL takes care of the data behind the scenes, and provides methods for sorting and arranging the data returned to queries. You never deal directly with the files that MySQL uses to store the data.
