In this section we’ll talk about data warehouses, ACID compliance, distributed databases and more.
via From Big Data to NoSQL: The ReadWriteWeb Guide to Data Terminology Part 2.
After linking to the Part 1 of this series of articles on ReadWriteWeb (all the way back in May), today there’s yet more terminology and info for the enterprising, goal-oriented technologists. Again, there’s some good info and a diagram to explain some of the concepts, and what makes these things different from what we are already using today. I particularly like finding out about performance benefits of these different architectures versus tables, columns and rows of traditional associative algebra driven SQL databases.
Where I work we have lots of historic data kept on file in a Data Warehouse. This typically gets used to generate reports to show compliance, meet regulations and continue to receive government grants. For the more enterprising Information Analyst it also provides a source of historic data for creating forecasts modeled on past activity. For the Data Scientist ir provides an opportunity to discover things people didn’t know existed within the data (Data Mining). But now that things are becoming more ‘realtime’ there’s a call for analyzing data streams as they occur instead of after the fact (Data Warehouses and Data Mining).
