Data access refers to the ability to retrieve and use information stored in databases or other storage systems. It allows users, such as data analysts or software applications, to obtain the data they need for analysis, reporting, or decision-making. Efficient data access is crucial for organizations to make informed choices based on accurate and timely information. There are various methods for data access, including SQL queries for relational databases and APIs for web services. These methods enable users to interact with data in different ways, ensuring that the right information is available when needed. Proper data access also involves security measures to protect sensitive information.
