📘 Topic: Existing Processes, Data, Applications, Tools and Their Integration
Subject: Information Technology Infrastructure
1. 📌 Introduction
Modern IT environments consist of multiple processes, data sources, applications, and tools. For smooth operation, these elements must work together in an integrated manner.
👉 Without integration, systems become inefficient, slow, and error-prone.
2. ✅ Definition
- Processes: Set of activities or steps performed to achieve a task
- Data: Information used and generated by systems
- Applications: Software programs used to perform tasks
- Tools: Utilities used to manage, monitor, or support IT systems
🔗 Integration
Integration is the process of connecting different IT components so they work together as a unified system.
👉 Simple idea:
Integration = linking everything so it works as one system
