" +++ Hue services are generic and let you integrate with other analytics systems for [querying](/user/querying/) and [browsing](/user/browsing/). Here is a list of the main APIs: * Connect or create SQL [autocompletes](/developer/parsers/) or connectors to any database (Impala, MySQL, Presto...) * Browse additional storage systems (HDFS, S3, ADLS, GS...) * List any jobs or queries (YARN, SQL queries, Kubernetes...) * Integrate with a [Data Catalog](user/browsing/#data-catalog) (Cloudera Navigator, Apache Atlas...) or a Query Optimization service In addition, whole new apps can also be created in order to provide end to end solutions. Majoritively, this section would be useful for: * Ramping-up with the overall Hue [development](/developer/development) project * How to improve the [SQL autocomplete](/developer/parsers/) for your own database * SqlAlchemy is becoming the [standard API](https://github.com/cloudera/hue/blob/master/desktop/libs/notebook/src/notebook/connectors/sql_alchemy.py) for databases other than Hive and Impala * Check some [contribution ideas](https://github.com/cloudera/hue/blob/master/CONTRIBUTING.md)
