## Summary

Transactional and analytical databases serve different workloads: OLTP handles high-volume, real-time reads and writes with ACID guarantees, while OLAP supports complex queries over large historical datasets for reporting and business intelligence. The comparison focuses on trade-offs involving latency, concurrency, data freshness, schema design, transaction size, and storage format. Row-oriented storage and normalized schemas support precise operational updates, whereas column-oriented storage and denormalized designs improve compression, scans, and aggregations across millions of rows. The source describes transactional systems as foundational for applications such as banking, e-commerce, healthcare, and reservations, while analytical systems support dashboards, forecasting, and ad-hoc analysis. Its recommended architecture is to run both systems independently and connect them with Change Data Capture, balancing operational reliability with analytical throughput.

## Context

Transactional and analytical databases make opposite trade-offs: operational systems need low-latency, highly consistent updates to individual records, while analytical systems need high-throughput scans and aggregations across large historical datasets. Using one system for both workloads can create performance, cost, and data-management challenges.

## Approach / What changed

Use separate OLTP and OLAP systems optimized for their respective workloads, then connect them with a Change Data Capture replication pipeline. Keep the transactional system as the source of truth, flow necessary changes into the analytical platform, and apply shared governance for security, access controls, and data lineage.

## Takeaways

- OLTP systems use row-oriented storage, normalized schemas, and ACID transactions to support low-latency updates and concurrent operational access.
- OLAP systems use column-oriented storage and denormalized designs such as star schemas or data vaults to improve compression, large-scale scans, and aggregations.
- Change Data Capture can replicate operational changes continuously instead of relying on nightly batches, helping synchronize analytical copies with lower latency.
