Data virtualization has unified siloed sources and now supports real-time decisions
The best features Denodo offers stand out to me as the ability to develop REST web services fast and easily, create and combine new views, integrate different sources of data, and connect with other tools seamlessly. When I mention fast and easy creation of views and integration, I love the agile data provisioning and integration, where Denodo provides a comprehensive set of capabilities for implementing logical data integration, management, and delivery, which in turn enables agile data analytics and an informed decision-making process to be smooth. I also appreciate the performance optimization with AI, which improves performance optimization through the integration of artificial intelligence capabilities. Furthermore, I appreciate the unified security and governance, where it addresses the need for an organization to effectively manage security, data privacy, and data protection easily, offering a centralized platform that allows the application of governance policies and fine-grained security controls. Another feature I would add about Denodo is that it also provides a single point of control where we can establish security controls over the entire infrastructure and gain visibility into all our data assets. Denodo has positively impacted my organization as since we started using this tool, it has been very helpful because it is a huge advantage that we can connect to many different databases to provide data rapidly and accurately and also gain insights, which helps us to make data-driven decisions easily. It has proven to be a valuable environment for deploying data virtualization solutions, and its user community is active in finding and fixing issues more accurately. Through data insights from Denodo, we have been able to improve our decision making, which helps to better communication between the stakeholders thanks to the real-time experience. It also saves a lot of time.

Has supported building flexible data pipelines and streamlined ETL orchestration
There should be a dedicated support team for Talend Open Studio. We do have a support team, but at times it is critical for us to fix certain things within one or two hours. Usually, the support team takes some 12 hours, which is the standard edition of support. If we could have round-the-clock support, we would be able to resolve many issues which we encounter during the development part. The initial setup for Talend Open Studio is a little complex. We need to have a dedicated person who has an understanding of Talend Open Studio as a tool. It takes some level of expertise, so it is not an easy process, but once we have a dedicated associate who is knowledgeable in that particular field, it becomes comparatively easier.
