Let me clarify this with an example from my experience at TCS, where I worked on a healthcare analytics dashboard for Humana. In that project, I had to integrate data from several external sources, including SQL Server databases, Excel files, and flat files. The main challenge was to ensure that the data coming from these different formats and sources remained consistent and reliable throughout the process.To address this, I designed SSIS packages that handled the extraction, transformation, and loading of data. During the transformation phase, I implemented data validation checks, such as verifying data types, handling missing or duplicate records, and standardizing formats. I also set up automated data quality checks to flag any anomalies before the data was loaded into the central repository.Additionally, I scheduled SnapLogic pipelines to automate data transfers and ensure timely updates. For reliability, I maintained detailed logging and error-handling mechanisms, so any issues could be quickly identified and resolved. By combining these strategies, I was able to deliver a robust data integration solution that provided accurate and up-to-date information for business users.
