Top 10 Data Warehouse Tools

Data Warehouse Tools

To thrive in today’s business environment, an organization needs accurate reporting and data analysis capabilities. Businesses should be able to consolidate and integrate data (from different resources) for different purposes, from customer service to partner integration to executive business decisions. This is where data warehousing comes into play, allowing for easy reporting and analysis. With the increase in data, businesses become increasingly reliant on data warehouses. Data warehouses are no longer merely a buzzword or an innovative idea; they have now become a mainstream method for storing data.

A data warehouse is a platform where data can be integrated precisely to generate meaningful business insights. With data warehousing, businesses can quickly access information, speed up query response times, and gain new insights into big data. Data warehouses have become significantly cheaper for businesses due to the emergence of cloud technology. A number of cloud-based data warehouse tools are available today, which are fast, highly scalable, and cost-effective. Modern data warehousing solutions automate the time-consuming and repetitive tasks associated with designing, developing, and deploying a data warehouse in response to fast-changing business requirements. Data warehousing tools are proving to be a go-to solution for managing ever-growing data volumes at several data-driven enterprises.

What is a Data Warehouse?

Data Warehouse is basically a platform to analyze large quantities of data from many sources to make business decisions. The purpose of a data warehouse is usually to compile and analyze business data from heterogeneous sources. By having access to critical data from a number of sources in one location, business users are able to rapidly make informed decisions on key initiatives. This saves them time by eliminating the need to retrieve data from multiple locations. Having your data organized in a single location allows you to perform analysis and reporting at a variety of aggregate levels. ​Data warehouses are mainly designed to support business intelligence (BI) and analytics activities. 

There are various actions that can be done on data using the Data Warehouse tools, including: 

  • Cleaning data and separating it from junk or duplicate data.
  • Extraction, transformation, and loading (ETL) of the data from various formats of sources into a single common format at the destination.
  • Querying data from warehouse in order to fetch, update, delete or analyze different combinations of data. 
  • Creating reports for analysis and business decision-making processes.

Types of Data Warehouse

There are mainly three types of data warehousing, which are as follows:

Enterprise Data Warehouse: These are centralized warehouses that provide decision-making support to different departments of an enterprise. They allow data to be organized and represented in a consistent manner. 

Operational Data Store (ODS): It is used when an organization’s reporting requirements cannot be met by OLTP (Online Transactional Processing) system. Since an ODS is updated/refreshed in real-time, it is ideal for routine operations such as storing employee records.

Data Mart: As a part of the data warehouse, a Data Mart is dedicated to a specific type of business line, such as accounting, finance, sales, purchases, or inventory, etc. By providing specific data to a defined group of users more quickly, it provides them with essential information.

Top Data Warehouse Tools

Below are a few Data Warehouse tools that you must know.

  • Amazon Redshift data warehouses consist of nodes (computing resources), which are organized into clusters. The Redshift cluster is continuously monitored, data from failed drives is automatically re-replicated and nodes are replaced when necessary.

Microsoft Azure

Microsoft Azure
Microsoft Azure

In 2010, Microsoft launched Azure, a cloud computing platform. In Microsoft Azure, there is an analytical data warehouse called SQL Data Warehouse (SQL DW), which is scalable for petabytes and built according to SQL Server. Basically, it consists of over 200 different products and cloud services, such as Data Analytics, Virtual Compute, Storage, Virtual Network, Internet Traffic Manager, Websites, Media Services, Mobile Services, Integration, etc. Through all of these services, highly scalable and efficient applications can be built, run, and managed across multiple cloud networks using AI (Artificial Intelligence) and Machine Learning.

Features:

  • It provides easy portability of data and a genuinely compatible platform between on-premises and public clouds. 
  • In order to improve performance and user experience, Azure offers a variety of cross-connection options, including VPNs (Virtual Private Networks), caching, and content delivery networks (CDNs).

Snowflake

Snowflake
Snowflake

Snowflake is a cloud-based Data Warehouse Tool that provides a faster, easier-to-use, and more flexible framework than other data warehouses. Since Snowflake runs completely in the cloud, it offers a complete SaaS (Software as a Service) architecture. Snowflake simplifies data processing by letting users work (data blending, analysis, and transformations) with varied forms of data structures (structured and semi-structured) using a single language, SQL.  

Features:

  • In the snowflake, combined structured (well-defined data model for effective analysis like a relational database) and semistructured data (data which does not conform to a data model but has some structure) can be loaded into the cloud database without being transformed into the same/fixed category.
  • Snowflake’s in-built software handles maintenance, and data is encrypted by default during transmission.
  • Snowflake’s multi-tenant architecture enables real-time data sharing across your organization. You don’t need to move data.
  • Snowflake provides scalable, dynamic computing power with charges based almost exclusively on usage. 
  • Snowflake has implemented features like auto-scaling (automatically start/stop clusters during unpredictable resource-intensive processing) and auto-suspend (stops the virtual warehouse when clusters have been sitting idle for a defined period) to ensure minimal administration.  Both of these concepts can increase flexibility, optimize performance, and lower management costs.

Teradata

Teradata
Teradata

Teradata DWH (Data warehouse) is a simple, cost-effective relational database management system offered by the Teradata organization.
