How Cloud Data Warehousing Works

Six critical stages of cloud data warehousing work together to consolidate, process, and analyze data in real-time. Here’s how each stage contributes to an efficient, scalable data management system:

1. Data Ingestion

• Cloud-based data warehouses extract data from many locations, including on-premise databases, cloud applications, APIs, and other IoT devices, to combine different data sets.
• Batch and Streaming Ingestion: Data can be batched (large datasets at a scheduled interval) or streamed (data flow in real-time, based on business needs).

2. Data Transformation and Cleansing

• Data Transformation is taking input as lower-dimensional data and converting it to higher-dimensional data points, i.e., converting categorical data into numerical data.
• First, the data is transformed and cleansed to be consistent, accurate, and compatible before storage.
• Of course, this often involves ETL (or ELT), the process of obtaining raw data that can be evaluated and analyzed.

3. Data Storage

• Cloud data warehouses alleviate the risk inherent to traditional storage by automatically scaling up the data volume to support any data volume needs.
• Data Partitioning and Compression: It partitions and compresses the data for storage efficiency and for faster data retrieval when querying.

4. Data Processing and Querying

• The processing engines used in cloud-based data warehouses are robust and support queries, data analysis, and model training in machine learning.
• The step here is optimized for performance and speeds up large datasets, which works for advanced analysis and reporting.

5. Data Access and Real-Time Analytics

• Business users and applications can access near-instantaneous insight through processed data from SQL queries, BI tools, and APIs.
• Real-time analytics capabilities allow organizations to make data-based decisions in time as the market changes and customer needs.

6. Data Archiving and Backup

• Built-in data archiving and backup functionality may continue to be used in data warehouses to support disaster recovery and remain compliant.
• It allows data to be stored in storage tiers with minimum fees but keeps data easily accessible.
