Feed: Featured Blog Posts - Data Science Central. Author: Adetayo Kolade. Power BI provides slicers for a single column, but there are scenarios where it could be useful to consolidate alternative filters for multiple columns in a single slicer. Technically, this is not possible in Power BI through the standard visualizations, but you can use a particular data modeling technique to obtain the desired result.Consider the case of a Customer table with a geographical hierarchy with Continent, Country, and State. The requirement is to enable a filter over California (State), France (Country), or Asia (Continent) using a single slicer, as shown in the ... Read More

Feed: MemSQL Blog. Author: Eric Hanson. The limitations of a typical, traditional relational database management system (RDBMS) have forced all sorts of compromises on data processing systems: from limitations on database size, to the separation of transaction processing from analytics. One such compromise has been the “sharding” of various customer accounts into separate database instances, partly so each customer could fit on a single computer server – but, in a typical power law, or Zipf, distribution, the larger database don’t fit. In response, database administrators have had to implement semi-custom sharding schemes. Here, we describe these schemes, discuss their limitations, ... Read More

Feed: Planet PostgreSQL. It is well known that database design should be as simple as possible, and follow the normalization process. Except in some cases, sometimes, for scalability purposes. Partitioning might be used to help deal with large amount of data for instance. But what is a large amount of data? Do you need to pay attention to those scalability trade-offs now, or can you wait until later? How far can you go with a naive schema? To answer those questions, it might be best to estimate the evolution of the size of your database in the following months. Here’s ... Read More
