Before You Start

Welcome to DataArts Insight. DataArts Insight is an all-in-one BI development platform for data visualization that offers visual, real-time, easy-to-use, and secure enterprise intelligence analysis services. It works with various data sources in the cloud and on-premises, offers a wide range of visualization components, and allows for easy data analysis and report building through drag-and-drop layout. It also enables quick customization of exclusive data screens.

You can use the APIs provided in this document to perform various operations on DataArts Insight, including accessing data sources, preparing datasets, analyzing data, and creating large screens. For a full list of supported operations, refer to Overview.

Basic Concepts

Account
An account is created when a user registers a Huawei ID and enables Huawei Cloud services. The account has full access permissions for all of its cloud services and resources. It can be used to reset user passwords and grant user permissions. The account is a payment entity and should not be used to perform routine management. For security purposes, create IAM users and grant them permissions for routine management.

Region
Regions are divided based on geographical location and network latency. Public services, such as Elastic Cloud Server (ECS), Elastic Volume Service (EVS), Object Storage Service (OBS), Virtual Private Cloud (VPC), Elastic IP (EIP), and Image Management Service (IMS), are shared within the same region. Regions are classified as common regions and dedicated regions. A common region provides common cloud services that should be made available to all tenants. A dedicated region provides services of a specific type or only for specific tenants.

For details, see Region and AZ.

AZ
An AZ contains one or more physical data centers. It has independent cooling, fire extinguishing, moisture-proof, and electricity facilities. Within an AZ, compute network, storage, and other resources are logically divided into multiple clusters. AZs within a region are interconnected using high-speed optical fibers to support cross-AZ high-availability systems.

Project
Projects group and isolate compute, storage, and network resources across physical regions. A default project is provided for each region, and subprojects can be created under each default project. Users can be granted permissions to access all resources in a specific project. If you need more refined access control, create subprojects under a default project and purchase resources in subprojects. Then you can assign users the permissions required to access only the resources in the specific subprojects.
