Data warehouse 2.0 in Big Data World

The new data warehouse, often called “Data Warehouse 2.0,” is the fast-growing trend of doing away with the old idea of huge, off-site, mega-warehouses stuffed with hardware and connected to the world through huge trunk lines and big satellite dishes.  The replacement is very different from that highly controlled, centralized, and inefficient ideal towards a more cloud-based, decentralized preference of varied hardware and widespread connectivity.
In today’s world of instant, varied access by many different users and consumers, data is no longer nicely tucked away in big warehouses.  Instead, it is often stored in multiple locations (often with redundancy) and overlapping small storage spaces that are often nothing more than large closets in an office building.  The trend is towards always-on, always-accessible, and very open storage that is fast and friendly for consumers yet complex and deep enough to appease the most intense data junkie.

Top Differences Read Today Agile vs Waterfall model

The Agile and Waterfall both models are popular in Software development. The Agile model is so flexible compared to waterfall model. Top differences on Waterfall vs Agile give you clear understanding on both the processes. Waterfall ModelThe traditional model is waterfall. It has less flexibility.Expensive and time consuming model.Less scalable to meet the demand of customer requirements.The approach is top down. Starting from requirements one has to finish all the stages, till deployment to complete one cycle.A small change in requirement, one has to follow all the stages till deployment.Waterfall model creates idleness in resource management. Agile ModelAgile model is excellent for rapid deployment of small changesThe small split-requirements you can call them as sprintsLess idleness in resource management.Scope for complete team involvement.Faster delivery makes client happy.You can deploy changes related to compliance or regulatory quickly.Collaboration improves among the team.
