Document Summary

Let"s clear up our basics with these terms before deep diving into dsa. Data structures these are like the ingredients you need to build efficient algorithms. These are the ways to arrange data so that they (data items) can be used efficiently in the main memory. Examples: array, stack, linked list, and many more. You don"t need to worry about these names. These topics will be covered in detail in the upcoming tutorials. Algorithms sequence of steps performed on the data using efficient data structures to solve a given problem, be it a basic or real-life-based one. Database collection of information in permanent storage for faster retrieval and updation. Data warehouse management of huge data of legacy data( the data we keep at a different place from our fresh data in the database to make the process of retrieval and updation fast) for better analysis.
