Go provides several packages for working with data storage and retrieval, including built-in support for SQL databases, as well as NoSQL databases like MongoDB and Redis.
For SQL databases, Go's standard library includes the
**database/sql** package, which provides a generic SQL interface that can be used with different database drivers. This allows developers to write code that works with different databases without having to change the underlying code. The
**sql** package also provides support for transactions, prepared statements, and connection pooling, which are all important features for building scalable applications.
In addition to the
**sql** package, Go also provides several popular SQL database drivers, including for MySQL, PostgreSQL, and SQLite.
For NoSQL databases, Go provides several third-party packages, including the
**mongo-go-driver** for MongoDB and the
**go-redis** package for Redis. These packages provide easy-to-use interfaces for working with these databases, including support for data retrieval, storage, and manipulation.
Go also provides built-in support for working with JSON, XML, and other data formats, making it easy to serialize and deserialize data in different formats. The
**encoding/xml** packages provide easy-to-use APIs for working with JSON and XML data, respectively.
Overall, Go's support for data storage and retrieval is extensive and includes support for both SQL and NoSQL databases, as well as different data formats.
