In this post, we review how organizations are integrating graph transactions and analytic processing and then dive deeper into graph algorithms. We’ll provide examples of using graph algorithms on Game of Thrones data to illustrate how to get started. Note that portions of this content have been taken from our O’Reilly book, Graph Algorithms: Practical Examples in Apache Spark & Neo4j, which you can download for free.» more

GQL - initiating an industry standard property graph query language
by Alastair Green (guest author), 30 May 2018

Azure SQL Data Warehouse, the hub for a trusted and performance optimized cloud data warehouse
by Arnaud Comet, Microsoft (sponsor) , 1 November 2017
Today, with the proliferation of data sources and the need to be data-driven, it is hard for companies to avoid siloed sources of information. Siloed data marts can represent an important increase in cost and potentially business opportunities. Centralizing data to provide more complete datasets to your internal departments, suppliers or customers can become a competitive advantage. In the context of Hub & Spokes, Azure SQL Data Warehouse is optimized to provide the greatest experience as a hub thanks to its native integration with Azure SQL Database and Analysis Services (the spokes).» more
We launched DB-Engines five years ago. This is a little summary of how it started and what we have achieved.» more
The Weight of Relational Databases: Time for Multi-Model?
by Luca Olivari (guest author), 29 August 2017
While computers and software have changed greatly in the past 47 years -- since the start of epic time -- there has been little innovation related to databases. Software requirements have changed dramatically over the past five decades; computing needs are vastly different.
In the 1970s, Intel introduced the first 4004 microprocessor that accessed only 640 bytes of memory. In the same period, the first relational database system was designed. RDBMS was invented from the paramount need to optimize storage and to utilize memory, efficiently. The world was an extremely different place. Almost everything in the computer hardware and software world has changed since then, except for relational databases. Are they still the best solution?» more
In the middle of the big data hype cycle, before IoT was on the top of everyone’s buzz list, before Cloud Native was common lingo and before large enterprises were starting the work to de-silo their infrastructure monitoring and metrics data, Paul Dix, Founder of InfluxData, began building a purpose-built Time Series Platform. Flash forward to today, time series is now the fastest growing database segment, and the market is clearly moving beyond the re-purposed Cassandra and Hbase implementations that defined the segment at that time. The following post is a firsthand account from Paul Dix outlining the problems he witnessed and why he built a modern Time Series Platform.» more

The popularity of cloud-based DBMSs has increased tenfold in four years

Enriching Property Graphs with Relationship Objects
by Jans Aasman (guest author), 21 June 2016
In many graph database applications we find that a link between two nodes is quite complex. Conventional property graph databases try to manage the complexity by putting properties on the edges between nodes, but this technique has significant limitations. To overcome the limitations, this article introduces the relationship objects pattern.» more

Data Modeling in Document Databases for the RDBMS-Minded
by Cihan Biyikoglu (guest author), 7 December 2015
Data modeling for relational databases uses entity relationship diagrams and normalization, techniques which have evolved to perfection over the years. However data naturally does not exist in this full normalized form in real world applications. Document databases provide flexible primitives like JSON documents for storing entities but this does not mean data modeling is a lost art!» more
The recent DB-Engines Ranking of December 2015 produced some surprises. Several systems, which continuosly showed a very positive trend (e.g. MongoDB, Cassandra, Redis, Neo4j) in the past, lost points in the recent ranking. Other major players, with a rather stuttering trend in the ranking so far, heavily increased their score (e.g. Oracle, MySQL, Microsoft SQL Server). Why did that come?» more
Master Data Management Remains Siloed Without Semantics
by Jans Aasman (guest author), 16 November 2015
As Big Data continues to grow, companies are increasing their commitments to extract every last drop of value from the information they gather. Since siloed data has limited value, organizations are also embracing a more comprehensive strategy of managing data across multiple data domains. But this requires a shift away from traditional Master Data Management (MDM) to broader and more flexible data governance environments that enable enterprises to quickly synthesize diverse data sources that can result in transformative business decisions.» more
Oracle, MongoDB, MySQL, ElasticSearch, Cassandra and MariaDB are the winners in the current ranking.
