Data integration tools are software applications designed to combine data from different sources into a unified view. They help organizations streamline their data management processes by allowing users to extract, transform, and load (ETL) data from various databases, applications, and systems. This integration enables better data analysis and reporting, leading to more informed decision-making. These tools can handle various data formats and types, making it easier to work with structured and unstructured data. Popular data integration tools include Informatica, Talend, and Microsoft SQL Server Integration Services (SSIS). By using these tools, businesses can improve data accuracy and accessibility across their operations.
