What is virtual data? 10 most common questions.

What is data virtualization? Data virtualization allows you to combine disparate data sources into a single “virtual” data layer, which provides integrated data services for real-time user applications.

Why is data virtualization the recommended approach for organizations looking for flexible data integration? In the era of big data, the Internet, the cloud, the explosion of data volumes and their heterogeneity, companies simply cannot afford to “store” all the data they need. Data virtualization is based on the value of all types of data, regardless of source, to provide integrated, standardized data services that are optimized for performance and flexibility, without the need for additional storage. replicated data.

Why is data virtualization more accessible and faster? Using VDR for secure document sharing. Increasing the physical movement and storage of data is expensive and slows down the pace of the business when changes are required. Data virtualization allows replication, but only when necessary. What are ideal designs or use cases for data virtualization? Any use case that requires access to heterogeneous data, real-time information, dynamic requirements, and short deployment times is ideal for data virtualization.

Reporting, a single view of customer data, logical data services, and integration with the network and the cloud are examples of projects in which data virtualization can replace or add value compared to traditional approaches. These are proven cases. Does data virtualization support web data integration? The Internet itself is a bulky, heterogeneous data source with dizzying growth. Only the data virtualization platform combines semantic and web automation tools that simplify and increase the reliability of retrieving web data and unstructured data and link it to corporate data to instantly create value for the business.

How does data virtualization manage data quality requirements? The platform includes tools for comparing, transforming, rewriting and enriching data based on sets of rules “on the fly” (and extensible using third-party tools). It can track changes in data sources and sources and inspire confidence in users. What about performance? The best data virtualization platforms use performance optimization techniques such as smart caching, scheduler management, transaction delegation, cost optimization, and rule-based optimization. asynchronous and parallel execution, etc. ensure scalability of the most demanding projects. The best performer in data virtualization.

Data virtualization can be used to expand the data warehouse, migrate, prototype, and combine multiple data sources to create virtual data warehouses. Integrates with messaging to provide flexible real-time data services for implementations. What is the cost and return on investment in data virtualization? A typical data virtualization project pays off in less than six months and costs a third of the cost of data replication methodologies or specific developments. Typically, return on investment (ROI) includes a significant reduction in hardware, software, storage, development, and maintenance costs. The experience of a specialized provider of data virtualization solutions undoubtedly accelerates the return on investment.

Virtualization is “a set of hardware and / or software technologies that allow you to manage multiple operating systems and / or multiple applications on the same machine separately from each other, as if they were running on separate physical machines”.

Virtualization consists in inserting the level of abstraction between the client and the supplier in the broad sense of the word. To better understand virtualization architectures in the context of an information system, it’s interesting to know the story. Virtualization began in the mid-1960s on the mainframe platform. At that time, virtual machines were called pseudo-machines. Initially, the central computer used a control program to allocate resources and isolate various pseudo-machine instances from each other. Two computer scientists, in 1974, laid the foundation for virtualization in their article, “Formal Requirements for Third Generation Virtualizable Architectures,” published in July 1974.
