The database (DB) is one of the active communities dealing with the non-functional requirements (NFRs) when designing advanced applications. The fulfillment of the NFRs is usually performed along thedoi:10.1007/978-3-319-51963-0_34Steffen, Bernhard...
Industry independent solution, by design The best way to achieve the kind of flexibility required, not just for today’s data needs but also to insure against future changes, is to leverage standardised technologies. Using standardised architectures means thatindustry-specific logic and design can be...
You are now going to create datasets by importing the tables and views from the connected data warehouse to the LDM Modeler. When a table/view is being imported, the LDM Modeler tries to auto-detect the types of the data in the table/view. The data can be ...
A data model helps design the database at the conceptual, physical and logical levels. Data Model structure helps to define the relational tables, primary and foreign keys and stored procedures. It provides a clear picture of the base data and can be used by database developers to create a ...
Big data integration Distributed databases Near real-time OLAP 1. Introduction Traditionally, data analytics have been executed on large data warehouses whose data is periodically extracted from OLTP databases and loaded as part of a long-running ETL (extract, transform, and load) process. However,...
In addition, new data attributes can beadded to a data modelmuch faster now, according to Young. That might take weeks in the Oracle data warehouse, but it can be done on the fly in the Denodo software when data sets are joined together, he said. "It gives us the flexib...
