A column can have a different datatype. Datatypes are often RDBMS dependent, but there are often equivalent types with a slightly different name. The following types are often available: *integer*: to store integral numbers *float*: to store floating point values *varchar*: to store variable length strings *char*: to store fixed length strings *date*: to store dates *timestamp*: to store timestamps *blob*: to store (large) amounts binary data *clob* or *text*: to store (large) amounts of text
