What is Data Warehouse Modernization?

Today, most businesses aspire to move their data warehouse to cloud-based platforms such that they can take benefit of the reliability, availability, and scalability provided by them. Moreover, since companies today are dealing with an ever-increasing data source, they must ensure that the data warehouse will be effective enough to sustain the reforming needs of your expanding business.

Presently, businesses seek to modernize their data warehouses by driving agile approaches that emphasize automation and reduce manual intervention. This methodology not only encourages the use of the data warehouse for a broad range of functions and processes but also enhances efficiency by minimizing the requirement to develop and deploy modern data warehouse architecture from scratch.

Data warehouse modernization approaches also involve increasing focus on flexible architectures and support for several data sources, enabling companies to combine their data from multiple touchpoints. Nonetheless, like any initiative, it is crucial to assess the benefits and potential challenges to make sure you are ready for your next big data warehousing project. The fact that every business is unique, a detailed assessment of these advantages and problems will help you to develop a robust data warehouse architecture to ensure you can fully reap the advantages of a modern data warehouse.

Data Warehouse Modernization Benefits

A modern data warehouse provides companies with the agility needed to grow and make smarter data-based decisions. Some of the benefits of how data warehouse modernization can help you build your business are:

Benefits of Data Warehouse

1. Supports advanced analytics requirements:

Data analytics is the focal point of any organization. They need to extract valuable insights from data coming from several touchpoints, which are present in multiple formats. A modernized data warehouse not only helps you to integrate data easily but also to draw the right data and valuable insights. It also helps you to bring data from other sources and look at how the growth of specific teams is dependent on that of others. This, in turn, makes it easy to find and weed out mistakes and helps in making decisions that will support the growth of any business.

2. Provides high speed and effective performance:

In this competitive world, a slight delay can lead to heavy losses for companies. Businesses today are required to act quickly to make sure that they don’t lose users to their competitors. Modernized data warehouses ensure that you are always accessible and available without impacting the efficiency and productivity of your expanding business. Data warehouse modernization is developed to support big data volumes, offering you a snapshot of your business and where it stands.

3. Reduces costs:

Having a robust data warehouse as the core of your business intelligence infrastructure can reduce costs related to purchasing several data integration tools to segment data silos. As these warehouses are created for user-friendly accessibility, you don’t need to hire extra personnel to extract data, make reports and conduct analyses. Integrating a modern data warehouse helps you save on maintenance costs linked with finding data loss throughout the ETL procedure or low-quality data which is unsuitable because of inadequate validation during source-to-data warehouse mapping.

With features like data quality and high security, a modern data warehouse helps to reduce costs linked with lost data or data that is left unused because of inferior quality.

4. Agility and elasticity:

To adapt to changing demands, growing companies are experimenting with diverse data modeling techniques. Modernizing the data warehouse and incorporating a flexible infrastructure enables these companies to achieve greater agility and access various data sources while avoiding compatibility and integration issues.

Modernizing the data warehouse simplifies the process of extracting valuable insights and increases business flexibility. Moreover, when using modernized data warehouse that depends upon the agile methodology, there is no need to manually reconstruct data models and ETL flows every time new data needs to be integrated. Agile data modeling enables you to update and redeploy models quickly and regularly to improve your data architecture.

Data Warehouse Modernization Challenges

No doubt, there are several big benefits of a data warehouse, but it is equally significant to look at the other side of the facility. There are a few common data warehouse challenges that you should consider while building your modern data management plan. Some of the data warehouse modernization challenges are:

1. Lack of governance:

Ideally, a data warehouse must include data from all endpoints and functions to avoid any gap in the system. However, companies may have to encounter issues if they mistakenly overlook compliance and governance guidelines.

Thankfully, data warehouse modernization overcomes these issues by introducing an abstraction layer that serves as a barrier between the end users and source systems. This enables businesses to devise several data marts that supply data based on their needs while ensuring that regulatory requirements are fulfilled throughout the reporting mechanism.

2. Access control:

Creating a data strategy framework for access control is extremely critical when dealing with data warehouses. Mostly, companies struggle to discern and define which personnel or department require access to the data warehouse. Failure to manage resources and provide permissions effectively leads to an unavoidable load on the system, causing a blockage that could have been avoided.

3. Ineffective data strategy:

Developing a well-focused data strategy is significant when designing or modernizing the data warehouse. The lack of an effective data strategy causes the team to not understand and embrace the benefits offered by their modern data warehouse. Collaboration among stakeholders is significant to make an effective data strategy, hence, creation, design, and planning are required to be part of a continuous process.


To conclude, it is crucial to import data into your data warehouse from multiple sources to get a detailed view of your business processes and operations. Due to this, all major modern data warehousing and management solutions should help integrate famous cloud-based databases, applications, and platforms like Oracle, Redshift, MS Azure, and Snowflake. By driving the specific capabilities and features of these data sources and including them in the data management process, you can enhance your business operations efficiency and increase utility.
