## What is ScalarDB?

ScalarDB is a hybrid transaction/analytical processing (HTAP) engine for diverse databases. It runs as middleware on databases and virtually unifies diverse databases by achieving ACID transactions and real-time analytics across them to simplify the complexity of managing multiple databases or multiple instances of a single database.

As a versatile solution, ScalarDB supports a range of databases, including:

- Relational databases that support JDBC, such as MariaDB, Microsoft SQL Server, MySQL, Oracle Database, PostgreSQL, SQLite, and their compatible databases, like Amazon Aurora, Google AlloyDB, TiDB, and YugabyteDB.
- Relational databases that support JDBC, such as MariaDB, Microsoft SQL Server, MySQL, Oracle Database, PostgreSQL, SQLite, and their compatible databases, like Amazon Aurora and YugabyteDB.
- NoSQL databases like Amazon DynamoDB, Apache Cassandra, and Azure Cosmos DB.

For details on which databases ScalarDB supports, refer to [Databases](requirements.mdx#databases).
