Records to Store Data
Records are a way to store structured data. Unlike arrays or lists that store only one type of data, records can store multiple types of related data under one name, allowing for a more organised approach when handling complex data.
What is a Record?
- A record is a data structure that groups different fields (variables) to represent an object or entity.
- Each field in a record can have a different data type (e.g., string, integer, boolean).
- For example, a record for a student might include fields for Name (string), Age (integer), and Grade (string).
Use of Records to Store Data
- Organise Data: Records help organise data that belongs together. For instance, if you're managing student information, all relevant details like name, age, and grades can be stored within one record.
- Access Data Easily: You can access any field in a record by using the record name and the field name, which makes it easier to handle specific pieces of data.
- Store Multiple Data Types: Records allow storing different data types under a single structure, unlike arrays, which typically store only one type of data.
Benefits of Using Records
- Clarity: Records group-related data, making it clearer and easier to understand.
- Flexibility: You can store different data types together in a single structure.
- Efficiency: Accessing or modifying fields in a record is simple and efficient.

Key Points to Remember
- Records are used to store multiple related data types under one structure.
- They allow for efficient and organised data management, especially for complex data sets.
- Fields in records can be easily accessed and updated by using the record's name and field.
