Secure and Reliable
Integrates with Database Security Service (DBSS) to better protect user privacy and data security with network isolation and security group rule setting options. Adopts HA design and transparent data encryption to ensure high data and system reliability.
Easy to Use
A unified console helps you easily manage data warehouses and focus on data and service. DWS is compatible with Oracle, PostgreSQL, and Teradata so you have the freedom to choose. Simple-to-use database migration tool allows you to smoothly move heterogeneous databases over with complete confidence.
Supports real-time data import to databases, T+0 agile service analysis and decision-making, and correlation analysis on at-scale data within seconds. Provides enterprise-class capabilities such as OLAP analysis, statistics analysis, and self-service analysis.
Various Import Modes
Batch import of data from OBS and MRS adds speed and efficiency. Working with DIS, CS, and DLI, DWS helps you quickly and conveniently import streaming data. The service also uses third-party ETL and CDM for data migration and supports real-time data writing using Copy interfaces driven by JDBC.
Data Warehouse Migration
The data warehouse is an important data analysis system for enterprises. As the service volume grows, performance of self-built data warehouses cannot meet the actual service requirements due to their poor scalability and high costs. As an enterprise-class data warehouse on the cloud, DWS features high performance, low cost, and easy scalability, satisfying requirements in the big data era.
DWS provides various migration tools to ensure seamless migration of popular data analysis systems such as Teradata, Oracle, MySQL, SQL Server, PostgreSQL, Greenplum, and Impala.
DWS supports the SQL 2003 standard and stored procedures. It is compatible with some Oracle syntax and data structures, and can be seamlessly interconnected with common BI tools, smoothing service migration efforts.
DWS supports data encryption and interconnection with DBSS to ensure data security on the cloud, as well as automatic full and incremental backup of data to improve data reliability.
Converged Big Data Analysis
Data has become the most important asset. Enterprises must be able to integrate their data resources and analysis platforms with high precision to mine the full value of their data. In predictive analysis use cases, massive volumes of data must be processed. Huawei DWS delivers the needed processing power to handle these intense compute scenarios.
The DWS SQL serves as the unified entry of upper-layer applications, so that application developers can access all data using the SQL.
Analysis personnel can obtain immediately-actionable information about an analysis request from the big data platform in real time.
Adding nodes allows you to easily expand into PB-range capacity while enhancing query and analysis performance of the system.
Enhanced ETL + Real-Time BI Analysis
The data warehouse is the pillar of the BI system for collecting, storing, and analyzing massive volumes of data. It powers business decision analysis for the IoT, finance, education, mobile Internet, and O2O industries.
Ability to import data in batches in real time from multiple data sources.
Cost-effective PB-level data storage and response to correlation analysis of trillions of data records within seconds.
Real-time consolidation of service data to produce actionable insights in operational decision-making.
Real-Time Data Analysis
In the mobile Internet and IoT domains, huge volumes of data must be processed and analyzed in real time to extract the full value from data. The quick data import and query capabilities of DWS accelerate data analysis capabilities to enable real-time ingestion, processing, and value generation.
Data from IoT and Internet applications can be written into DWS in real time after being processed by the stream computing and AI services.
Device monitoring, control, optimization, supply, self-diagnosis, and self-healing based on data analysis and prediction.
You can conduct correlation analysis on results of image and text data analysis (by AI services) and other service data on DWS.
