Pick a technology to start. Each one moves from what it is, to how it behaves, to what happens when it's pushed.

Relational database engine — MVCC concurrency, indexing, query planning, transactions, WAL durability, and streaming replication.

Document database — flexible schemas, indexing, the aggregation pipeline, multi-document transactions, replication, and sharding.

Wide-column store — partitioning, replication, tunable consistency, the gossip protocol, and compaction across a masterless cluster.

Full-text search engine — inverted indexes, relevance scoring, sharding, and near-real-time distributed search at scale.
