ebay, the online auction site, has open source for its database technology, called Kylin, which says it can quickly query petabytes of data stored in Hadoop. ebay is not a big data user compared to companies like Google and Facebook, but it does also run technology solutions such as Hadoop on a sizeable scale, and the Kylin project appears to be a great example of how it is based on technology innovation.In a post in 20th last month, EBay unveiled specific information about the Kylin project, th

effectively perform analytics, you need a data warehouse. A data warehouse is a database of a different Kind:an OLAP (Online analytical Processing) database. A data warehouse exists as a layer on top of another database or databases (usually OLTP databases). The Data warehouse takes the data from any these databases and creates a layer optimized for and dedicated to analytics. The answer to the question I posed above are THIS:A database designed

Basic concepts: 1. Multi-dimensional dataset: a multi-dimensional dataset is the main object in Online Analytical Processing (OLAP) and a technology that allows quick access to data in a data warehouse. A multi-dimensional dataset is a collection of data. It is usually constructed from a subset of a data warehouse, and is organized and aggregated into a multi-dimensional structure defined by a set of dimensions and measurement values. 2. dimension: i

Data WarehouseThe middle of the 80 century, "the father of the Data Warehouse Mr. William H.inmon defined the concept of data warehousing in his book" Building Data Warehouses, "and then gave a more precise definition: The Data Warehouse is a topic-oriented, integrated, time-related, and relevant in business management and decision making, A collection of data that cannot be modified. Unlike other database applications, a data warehouse is more like a process for the integration, processing, and
