The Challenge

Our Approach

ProCogia migrated this team's legacy data from Oracle to Snowflake, applying custom ETL to meet the team's requirements such as parsing of unintelligible/numerical codes to human-readable names.

Amazon EMR was used for reading from Oracle DB to Snowflake due to limitations with Snowpark.

Numerous normalized Oracle tables were consolidated into a smaller set of denormalized Snowflake tables.

PII Data underwent anonymization processes within Snowflake's secure environment, ensuring enhanced data privacy and protection.

Daily QA counts were generated and displayed in a dashboard, so engineers and stakeholders could monitor daily/weekly/monthly data volume trends.

Architecture

Results

With the on-demand scalability of Snowflake, this team was able to run their queries in minutes rather than hours and days.

Better Security and maintenance with centralized auditing of user/role access.

The biggest success for business stakeholders was the enablement of large data aggregations for reverse billing, leading to the recovery of $2M in revenue.
