# Data Types in ClickHouse

This section describes the data types supported by ClickHouse, for example [integers](/reference/data-types/int-uint), [floats](/reference/data-types/float) and [strings](/reference/data-types/string).

System table [system.data\_type\_families](/reference/system-tables/data_type_families) provides an
overview of all available data types.
It also shows whether a data type is an alias to another data type and its name is case-sensitive (e.g. `bool` vs. `BOOL`).
