In this blog, Learn what is data, different types of data, how to store and analyse data and more which will help you understand the meaning and significance of data.
Schema integration has been revisited in the past decade in service-oriented computing since the input/output data-types of service interfaces are heterogeneous XML schemas. However, service integration differs from the traditional integration problem, since it should generalize schemas (mining abstract ...
Star schema acts as an input to design a SnowFlake schema. Snow flaking is a process that completely normalizes all the dimension tables from a star schema. The arrangement of a fact table in the center surrounded by multiple hierarchies of dimension tables looks like a SnowFlake in the Snow...

Unlike structured data, which is stored in data warehouses, unstructured data is stored in data lakes. Data lakes preserve the raw format of data as well as all of its information. Data lakes make data more malleable, unlike data warehouses where data is limited to its defined schema. Semi...

A data warehouse contains facts about the sales of each product at on a daily basis. A typical relational implementation for such a data warehouse is a Star Schema. The fact information is stored in the so-called fact table, whereas the dimensional information is stored in the so-called ...
