What is the main purpose of system integration in business IT?

The primary purpose of system integration in business IT is to connect various IT systems for seamless communication. This involves linking different applications, databases, and technology components so that they can work together effectively. When systems are integrated, organizations can streamline their processes, improve data accuracy, and enhance collaboration among departments. The elimination of data silos allows for better access to information and provides a comprehensive view of operations, which is crucial for decision-making and efficiency.

Seamless communication between different systems enables businesses to automate workflows, reduce manual data entry, and respond more quickly to changing business needs. As a result, integration can significantly improve productivity and operational efficiency, contributing to overall business objectives.

The other options, while they may have relevance in specific scenarios, do not capture the fundamental aim of system integration as effectively. Enhancing internet security and ensuring compatibility with all software are important aspects but not the core purpose of integration itself. Likewise, increasing software licensing does not directly relate to the core goals of system integration in enhancing communication and business processes.
