The Basics of Data Virtualization

Technology - The Basics of Data Virtualization

Data virtualization is a process for loading metadata and physical views from source systems into another database. These mappings define how information is converted for integration. The result is the creation of a virtual database that represents a set of semantically similar data assets. The data assets can be accessed in different ways, depending on the purpose of their use. Data virtualization can help with this problem. In this article, we will explore the basics of data virtualization.


The term “federation of data” describes the process of connecting multiple data sources and presenting it under a single, unified dashboard. Instead of replicating data, this technology makes data virtual so it can be accessed by multiple systems simultaneously. Data federation benefits businesses by reducing the infrastructure costs associated with managing data. By reducing the number of physical data stores, it can also save a company up to 75 percent on IT costs. Understanding the concept of data federation is an essential step in deciding whether to implement it in your organization.

A common problem associated with data silos is that companies use different databases for different business purposes. Typically, large enterprises have 40 separate databases for different applications, each with its own data model. This causes a number of problems. A data federation solution should avoid large databases in these cases. To ensure the reliability of the data, it is best to store it in some form, such as an XML file. Because data federation relies only on the latest information, it’s important to retain some historical data in some form. In addition, data federation will only contain the latest data. Physical data storage systems are still required for historical data.

A typical example of data federation is when a grocery store stores transaction details in an Oracle database. It then launches an online purchase business backed by a PostgreSQL database. In this case, an analyst would want to query the number of cornflakes boxes sold in a particular week. To do this, the analyst submits a query to the data federation layer, which then forwards the query to the underlying systems and combines the results. Once the data federation layer is satisfied with the result, the query is returned to the source.

Data Fabric

A data fabric is a unified layer that can ingest any type of data and process it. It can also store and process data from multiple sources. There are several providers, including IBM Cloud Pak, K2View, Denodo, Talend, and Informatica. Each provider has its own strengths and weaknesses, but they all provide similar capabilities. These providers provide a unified layer for data management, as well as support for complex queries and a range of other features.

Today’s global enterprise organization may have data that is spread across multiple clouds and on-premises. These data types represent a vast range of technologies, from relational databases to flat files to data lakes and stores. Because data is spread across so many platforms and applications, it can be difficult to manage the workloads associated with it. Using a data fabric consolidates data management into one environment and automatically manages these disparate data sources and technologies.

However, data virtualization is still a more affordable solution and may be the best choice if your requirements are straightforward. In fact, data virtualization is the fastest way to integrate disparate data sources, offering numerous connectors for different types of sources. It can also organize data for dashboards and reports. However, a data fabric requires much more planning and a multidisciplinary team comprised of developers, business analysts, data architects, and security professionals.

Regardless of the type of data you need, a data fabric can help you leverage the full value of data across hybrid multicloud environments. A logical data fabric can be built around the different sources and databases to create a single, consolidated view of data. This enables you to make better decisions with data, and avoid the costs and delays that come from moving it from one cloud to another. And because of its high-performance capabilities, a data fabric is the solution you need to take to make the most of your data.

Data Mesh

In the last decade, many companies have made the transition from monolithic data warehouses to distributed and federated systems, and data virtualization is no different. These new models treat data sources and data services like any other data. As such, data from existing databases, such as relational databases, can continue to be used for new analytics and other purposes. The data products created using these technologies would still adhere to the same data governance protocols and policies.

Choosing the right data mesh architecture is not an easy task, however. Many factors need to be taken into consideration, including the skills of domain teams and the availability of infrastructure. Often, organizations are engineering-oriented and are open to building the technology themselves. In addition to evaluating the requirements of the stakeholders, organizations must consider their innovation cycle and organizational culture to find the right strategy. In most cases, an appropriate data mesh architecture enables generalist technologists to build data products and directly serve consumers.

The fundamental benefits of data virtualization include reducing the cost of data management, increasing security, and simplifying management. By consolidating and implementing data infrastructure into multiple, self-service layers, organizations are able to access their data from wherever it lives. Data virtualization is also more efficient than traditional ETL, which involves integrating data from various sources and re-analyzing them as needed. Ultimately, data mesh provides significant benefits and will allow organizations to take advantage of its full potential.

The proper data mesh requires a federated and domain-oriented approach to data management. It should include a mix of domain-oriented data ownership, data-in-motion, and self-service access, as well as strong data governance. This approach will require some cultural shifts and a commitment to cross-functional business domain modeling. To be successful, organizations should also implement strong federated data governance models and self-service data tooling for non-technical users.

Data Lake

The blending of different data sources, known as virtual data lake, is becoming increasingly common for companies. These platforms use distributed access control, connect to disparate systems, and hold summaries of data in those systems. They make it easier for applications to search and change data across the sources. While data virtualization has its benefits, it is important to understand its limitations. Read on to learn how data virtualization can benefit your business.

Data virtualization and data lake are closely related technologies. In fact, data virtualization allows users to use both warehouses and data lakes. It allows users to curate and integrate data without moving or transforming it to meet business requirements. One EMIS executive described how data virtualization helped him create a best-of-both-worlds scenario, in which the data scientist can run analysis on the raw data while the data analyst can wait a few hours for curated data.

Physical data movement is expensive, inefficient, and inflexible. A flexible data environment is needed to quickly prototype and test new initiatives. It must also be accessible in real time or near-real-time. BI tools also need access to the same data sources. Data virtualization technology is already used by companies in a variety of industries. With these benefits, it is not hard to see why this technology is increasingly becoming the preferred choice for many organizations.

The data virtualization and data lake concept will become the core strategy of every organization within the next five to 10 years. Startups such as Varada are disrupting the data management space with indexing-based technologies. They allow users to gain access to data and empower their data teams to optimize it at a rapid rate. It is possible to achieve all these things while keeping costs low. So, what is data virtualization and data lake?

Data Warehouse

In this article, we will discuss how Data Warehouse virtualization can help your organization. Data warehouse virtualization provides companies with a cost-effective and flexible way to store and analyze big data. Various solutions exist for this purpose, such as software-as-a-service offerings. Datometry Inc. recently raised $17 million in Series B funding. Its products enable companies to run existing applications on a cloud data warehouse without rewriting them.

The traditional Data Vault pitch emphasizes creating a single version of facts and pushing business logic upstream. The problem with this approach is that users don’t always need the same data warehouse tools. To make things better for users, engineers had to create complex data pipelines. This approach often resulted in data leaving the source system and losing control and security. Therefore, it is critical to implement data warehouse virtualization. This will help you gain the insight you need and the resources you need.

One benefit of data virtualization is that it can reduce your time to market by eliminating the need to copy data from one location to another. Moreover, it offers improved data governance and security. With data virtualization, users can access data from wherever they need it. In addition, they can even perform analysis and design reports. All of this will reduce costs and increase efficiency. Data virtualization is an excellent solution for companies that need to centralize security and provide their consumers with the right data.

Another benefit of Data Warehouse virtualization is that it can be used for integration with other data sources. The data virtualization process involves loading the metadata and physical views of data from source systems, allowing them to be merged into a single data warehouse. Using a staging database, for example, eliminates the need for the end user to connect to several source systems to access data. The data virtualization process also ensures traceability.
