There are a lot of types of databases out there. Which one you use depends on what you need it for. Here are a few examples 👇🧵

▶️ RELATIONAL DATABASE
This is the most popular database out there. It depends on tables which have relationships between them (thus "relational"). Popular examples include:
👉@MySQL
👉 @PostgreSQL
👉 @SQLServer
▶️ NOSQL DATABASE
The opposite of a relational database. It doesn't rely on tables and relationships, which is why it's called No-SQL. It is instead (usually) reliant on documents. Popular examples include:
👉 @MongoDB
👉 @couchbase
👉 @dynamodb by @awscloud
▶️ GRAPH DATABASE
Databases that use "graphs" instead of tables for data. Graphs use nodes and edges to express relationships between entities. Examples:
👉 @neo4j
👉 @awscloud Neptune
▶️ KEY-VALUE STORE
Databases optimised for storing "dictionaries" or key-value pairs. Most popular example:
👉 @RedisLabs
▶️ TIME SERIES DATABASE
Databases optimised for storing "time series" data (data indexed in time order), used for (for example) trends. Example:
👉 @InfluxDB
