Accessing DWS

The following figure shows how to use DWS.

Figure 1 Process for using DWS

Accessing a Cluster

DWS provides a web-based management console and HTTPS-compliant APIs for you to manage DWS clusters.

In cluster deployment, if a single node is faulty, the abnormal node is automatically skipped when DWS is accessed. However, the cluster performance will be affected.

Accessing the Database in a Cluster

DWS supports database access using the following methods:
  • DWS client

    Use the DWS client to access the database in the cluster. For details, see "Cluster Connection" in the Data Warehouse Service (DWS) User Guide.

  • JDBC and ODBC API calling

    You can call standard APIs, such as JDBC and ODBC, to access databases in DWS clusters.

    For details, see "Using the JDBC and ODBC Drivers to Connect to a Cluster" in the Data Warehouse Service (DWS) User Guide.

End-to-End Data Analysis Process

DWS has been seamlessly integrated with other services on Huawei Cloud, helping you rapidly deploy end-to-end data analysis solutions.

The following figure shows the end-to-end data analysis process. Services in use during each process are also displayed.
