Example Scenario

This getting-started guide describes how to complete end-to-end data operations on DataArts Studio.

In this case, MRS Hive is used as the data lake foundation, and DataArts Studio is used for end-to-end governance of taxi trip data of a city. The following objectives are expected to be achieved through data governance:
  • Standardized data and models
  • Unified statistics standards and high-quality data reports
  • Data quality monitoring and alarm
  • Daily revenue statistics
  • Monthly revenue statistics
  • Statistics on the revenue proportion of each payment type

Process Overview

You can govern data in the example scenario based on the process in Table 1.

Step 3: DataArts Migration

Use DataArts Studio to upload data from data sources to the cloud.

You can migrate offline or historical data. DataArts Migration can migrate a single table, file, entire database, and incremental data. You can use it to migrate data between homogeneous and heterogeneous data sources such as on-premises and cloud-based file systems, relational databases, data warehouses, NoSQL databases, big data services, and object storage.

Step 7: DataArts Quality

Use DataArts Quality to monitor metrics. You can filter out unqualified data in a single column or across columns, rows, and tables from the following perspectives: integrity, validity, timeliness, consistency, accuracy, and uniqueness. DataArts Studio uses automatically generated quality rules to standardize data, and supports periodic monitoring.
