    +**Note:** Table API and SQL queries can be easily integrated with and embedded into DataStream
or DataSet programs. Have a look a the [Integration with DataStream and DataSet API](#integration-with-datastream-and-dataset-api)
section to learn how DataStreams and DataSets can be converted into Tables and vice versa.

     -------------------------
     
    -A `Table` is always bound to a specific `TableEnvironment`. It is not possible to combine
Tables of different TableEnvironments.
    +The `TableEnvironment` is a central concept of the Table API and SQL integration. It
is responsible for:
    +* Registering a `Table` in the internal catalog
    +* Registering an external catalog 
    +* Executing SQL queries
    +* Registering a user-defined (scalar, table, or aggregation) function
    +* Converting a `DataStream` or `DataSet` into a `Table`
    +* Holding a reference to an `ExecutionEnvironment` or `StreamExecutionEnvironment`
    +
    +A `Table` is always bound to a specific `TableEnvironment`. It is not process tables
of different TableEnvironments in the same query, e.g., to join or union them.
