What this session would cover
Proposed outline — the mentor finalises the agenda once this topic is scheduled.
- 1Why database internals & administration matters — the common problem: Production databases stall on locks and backups have never actually been restored.
- 2Core concepts in plain language: Storage engines, B-trees, log-structured merge trees, write-ahead logging, multiversion concurrency control, query planning
- 3Going further: locking, replication, partitioning, sharding, backup, recovery
- 4Framework walkthrough: Normalization, Dimensional Modeling, ELT Pipelines, Data Quality Dimensions
- 5Practical workflow, built live: A lock-contention diagnosis, replication setup notes and a verified backup-restore runbook.
- 6How to measure it: Query latency, Pipeline freshness, Data-quality check pass rate, Failed job rate
- 7An illustrative case (a fictional example, not a client result), then live Q&A on your own situation
Who it's for
- • Students and freshers entering tech
- • Working developers and engineers
- • Tech leads and architects
You'd leave with
- A lock-contention diagnosis, replication setup notes and a verified backup-restore runbook.
- A working understanding of Normalization and Dimensional Modeling
- A short list of measures to track: Query latency, Pipeline freshness, Data-quality check pass rate
