Data Import
Data import is the process of transferring data from external sources into a system, application, or database for storage, analysis, or processing. It involves extracting data from formats like CSV, JSON, XML, or databases, transforming it as needed, and loading it into the target environment. This is a fundamental step in data integration, ETL (Extract, Transform, Load) pipelines, and data migration workflows.
Developers should learn data import techniques to handle data ingestion in applications, such as importing user data from spreadsheets, integrating third-party APIs, or migrating legacy systems. It is essential for building data-driven applications, business intelligence tools, and automated data processing systems, ensuring data consistency and accessibility across platforms.
