Data structure is a method of collecting and organising data in such a way that we can effectively conduct operations on it. Data Structures are used to organise and store data by presenting data items in terms of some relationship. For example, we have information about a player named "Virat" who is 26 years old. The data types "Virat" and "26" are both String data types. We may organise this information into a record called Player, which will contain both the player's name and age. As a data structure, we can now gather and store player records in a file or database. For instance, "Dhoni" is 30, "Gambhir" is 31, and "Sehwag" is 33. If you're familiar with Object Oriented programming principles, you'll recognise that a class accomplishes the same thing: it aggregates several types of data into a single entity. The only distinction is that data structures give strategies for efficiently accessing and manipulating data. Data Structures, in simple terms, are structures that are programmed to contain ordered data so that various operations may be performed on it quickly. It indicates the data knowledge that needs to be stored in memory. It should be planned and implemented in a way that minimises complexity while increasing efficiency.
