2 Advantages

Diverse Visual ComponentsDLV provides various visual components, including common data charts, graphs, andcontrols.

Professional Display of Geographical InformationDLV supports display of geographic tracks, flying lines, heatmaps, regions, and 3D globe, andallows layering of geographical data.

User-friendly GUIDLV allows you to build screens only by drag-and-drop without programming. You cancustomize the screen size based on the device resolution.

Various Data SourcesDLV can seamlessly integrate with Data Warehouse Service (DWS), Data Lake Insight (DLI),Relational Database Service (RDS), and Object Storage Service (OBS), and supports localCSV files, online APIs, and the private cloud data of enterprises.

7 Restrictions

Before using DLV, be aware of the following use restrictions:

l DLV is deployed in the following region:– CN North-Beijing1– CN North-Beijing4– CN South-Guangzhou– CN East-Shanghai2

l The supported browser types and versions are listed as follows:– Google Chrome 59 or later

l A connection agency is required for accessing data sources in a VPC. To create aconnection agency, you need to log in to the CDM management console and create aCDM cluster as a connection agency in the same VPC as the data sources.

8 Basic Concepts

Region

A region is a physical location where DLV is deployed. Availability zones (AZ) in the sameregion can communicate with each other over an intranet but AZs in different regions cannotcommunicate with each other.

HUAWEI CLOUD data centers are built in multiple regions, such as North America, Europe,and Asia. DLV can be deployed in those regions. By creating DLV in different regions, youcan design applications to better meet customer requirements and comply with local laws andregulations.

AZ

An AZ is a physical region where resources use independent power supplies and networks.AZs are physically isolated but interconnected through an internal network. Each AZ providescost-effective and low-latency network connections that are unaffected by faults which mayoccur in other AZs. Therefore, using DLV in separate AZs protects your applications againstfaults that occur in a specific AZ.

Project

A project is a collection of resources and a minimum authorization unit. Users' resources mustbe mounted to a project. Projects are used to isolate resources between different departments,different projects, or different environments, such as the R&D environment, test environment,and production environment, in the same project.

Data Source

A data source is where data comes from. DLV provides multiple types of data connection:static data, APIs, databases, CSV files, and OBS.

Component

A component is a basic configurable module used to create a screen. DLV supports thefollowing types of components: regular charts, maps, media, text, relational networks,materials, interaction, and others.

Data Lake VisualizationProduct Introduction 8 Basic Concepts


CanvasA canvas is an interface editor used to edit components of DLV. On a canvas, you can designpage layout and match colors for components and associate data sources with charts. Allapplications are published only in the canvas.

LayerA layer refers to the precise positioning of a component on a screen. It is similar to a slide thatcontains elements such as text or graphics and is then combined with other slides in sequenceto produce the final effect of a page.
