• Data Reconciliation: Compare aggregated data, such as counts, sums, and averages, between the source and target systems. This helps to identify any data loss or inflation.

• Record-Level Comparison: Sample individual records from both systems and compare them field by field. This helps to identify any data corruption or transformation errors.

• Business Rule Validation: Verify that the data in NG ML adheres to all relevant business rules and constraints. For instance, ensuring that all dates fall within a valid range or that all required fields are populated.

Creating Automated Validation Scripts

Manual data validation is time-consuming and prone to error. Automating the validation process using scripting languages like Python offers several advantages:

• Efficiency: Automating accelerates the validation process, enabling faster identification of issues.

• Consistency: Automated scripts ensure that the same validation rules are applied consistently across the entire dataset.

• Scalability: Automated scripts can easily handle large datasets, making them suitable for complex migrations.

• Reproducibility: Automated scripts provide a repeatable and auditable validation process.

Here’s a conceptual Python code snippet that gives an idea of the automated validation script:

# Example of data reconciliation using Python and Pandas
import pandas as pd

# Load data from source and target systems
ugdldata = pd.readcsv("ugdldata.csv")
ngmldata = pd.readcsv("ngmldata.csv")

# Calculate total number of records in each system
ugdlcount = len(ugdldata)
ngmlcount = len(ngmldata)

# Compare total counts
if ugdlcount == ngmlcount:
print("Data reconciliation successful: Record counts match.")
else:
print("Data reconciliation failed: Record counts do not match.")
print(f"UG DL count: {ugdlcount}, NG ML count: {ngmlcount}")

#Further validations can be added (column data profiling/comparison, null value check etc.)

This shows how you can use automated scripts to do your validation.

Data Security: Considerations During Migration
