+Snowflake
+==========
+
+The connection to Snowflake is based on the `snowflake-connector-python <https://pypi.org/project/snowflake-connector-python/>`_ library.
+
+Dependency
+----------
+
+* snowflake-connector-python
+
+Parameters
+----------
+
+Required:
+
+* `user` is the database user.
+* `password` is the snowflake account password.
+* `database` is the database name.
+* `warehouse` is the snowflake warehouse name.
+* `account` is the snowflake account number ( can be found in the url ).
+* `schema` is the schema name.
+
+
+.. warning:: 
+
+     Provide the parameters of an already running ``Snowflake`` Data Warehouse. EvaDB only connects to an existing ``Snowflake`` Data Warehouse.
+
+Create Connection

+   };
+
+.. warning::
+
+    In Snowflake Terminology, ``Database`` and ``Schema`` refer to the following.
+    A database is a logical grouping of schemas. Each database belongs to a single Snowflake account.
+    A schema is a logical grouping of database objects (tables, views, etc.). Each schema belongs to a single database.
