Top 15 Popular Data Warehouse Tools

A data warehouse is a Data management system that is used for storing, reporting, and data analysis. It is the primary component of business intelligence and is also known as an enterprise data warehouse. Data Warehouses are central repositories that store data from one or more heterogeneous sources. Data warehouses are analytical tools built to support decision-making for reporting users across many departments. Data warehouse works to create a single, unified system of truth for an entire organization and store historical data about business and organization so that it could be analyzed and extract insights from it.

Data warehousing is the process of collecting data from several sources to store and allow them to be used to prepare the reports. It is effectively an optimized data store intended expressly to facilitate the conduct of data analytic procedures. Here’s a breakdown of its key characteristics

Key Characteristics of Data Warehousing

• Data Aggregation: Data warehousing also aggregates data from numerous sources such as transactional database systems, operational systems, or external data feeds. This data can be organized in some form or other like tables or even have no fixed format.
• Data Transformation: Data cleaning and data integration are used to prepare the data in a consistent and compatible format for the warehouse. This could mean cleaning up, organizing and structure the data.
• Subject-Oriented Organization: The data is selected according to the subject or business theme under consideration and not according to the IDs of applications. This makes subsequent analysis of the specific issues of that particular business easier.
• Historical Data Storage: Data warehouses are usually designed to retain historical data for a long period so as to be able to analyze data over a long period and generate useful trends.
• Analytical Reporting: The data warehouse architecture is best suited for data from queries and data mining tasks. They offer search options and features that enable users to track trends, make discoveries, and make further decisions that are based on the data.

Previously, organizations had to build lots of infrastructure for data warehousing but today, cloud computing technology has amazingly reduced the efforts as well as the cost of building data warehousing for businesses. Data warehouses and their tools are moving from physical data centers to cloud-based data warehouses. Many large organizations still operate data through the traditional way of data warehousing but clearly, the future of the data warehouse is in the cloud. The cloud-based data warehousing tools are fast, efficient, highly scalable, and available based on pay-per-use.  

There are various cloud-based Data Warehousing tools available. So, it becomes difficult to select top Data Warehouse tools according to our project requirements. Following are the top 8 Data Warehousing tools:
