  • Big data showdown: Cassandra vs. HBase

    By Rick Grehan | 02 April, 2014 21:06

    Bigtable-inspired open source projects take different routes to the highly scalable, highly flexible, distributed, wide column data store

  • HBase is massively scalable -- and hugely complex

    By Rick Grehan | 01 April, 2014 00:19

    Apache HBase describes itself as "the Hadoop database," which can be a bit confusing, as Hadoop is typically understood to refer to the popular MapReduce processing framework. But Hadoop is really an umbrella name for an entire ecosystem of technologies, some of which HBase uses to create a distributed, column-oriented database built on the same principles as Google's Bigtable. HBase does not use Hadoop's MapReduce capabilities directly, though HBase can integrate with Hadoop to serve as a source or destination of MapReduce jobs.

  • An introduction to Cassandra

    By Rick Grehan | 24 March, 2014 14:18

    Apache Cassandra is a free, open source NoSQL database designed to manage very large data sets (think petabytes) across large clusters of commodity servers. Among many distinguishing features, Cassandra excels at scaling writes as well as reads, and its "master-less" architecture makes creating and expanding clusters relatively straightforward. For organizations seeking a data store that can support rapid and massive growth, Cassandra should be high on the list of options to consider.

  • 4 free, open source management GUIs For MongoDB

    By Rick Grehan | 12 June, 2013 15:35

    MongoDB is certainly one of the most popular open source, document-oriented NoSQL databases. Developed and maintained by 10gen, MongoDB is available in both a free version and a paid-for enterprise version, which adds features such as Kerberos security, SNMP access, and live monitoring features. However, neither the free version nor the enterprise version comes with a management GUI.

  • NoSQL showdown: MongoDB vs. Couchbase

    By Rick Grehan | 21 March, 2013 10:07

    MongoDB edges Couchbase Server with richer querying and indexing options, as well as superior ease-of-use

  • Visual Studio 2012 shines on Windows 8

    By Rick Grehan | 31 October, 2012 16:05

    Visual Studio is no longer simply an IDE, no longer a place you go just to write and debug C/C++ code. It has long since become something of a development mashup. It's where you go to tackle any task in the development process, regardless of the target. It's where you head to do your LightSwitch development, your SQL Server development, your Web application development, your Windows Azure development, and your ASP.Net or Windows Forms development in C#, F#, VB.Net, and -- oh, yes -- good old Visual C++. Naturally, it's where you build applications for http://www.infoworld.com/category/tags/microsoft-windows-azure and Windows RT.

  • Programming Opa: Web development, reimagined

    By Rick Grehan | 01 February, 2012 22:07

    Building a Web application today means using a variety of different software technologies, each executing in a different domain. JavaScript, HTML, and CSS in the browser; PHP, Python, Java, Ruby, or the like on the server; MySQL, PostgreSQL, SQL Server, MongoDB, or any of a growing list of database servers as your persistent storage back-end. With Opa, an open source Web development technology from the French company MLstate, building a Web application tomorrow could be much more straightforward -- and safer.

  • First look: Zend's PHP developer cloud

    By Rick Grehan | 11 January, 2012 22:06

    When you consider the cloud, you typically imagine a realm of deployed, production applications. Zend Developer Cloud (ZDC) adds a twist: ZDC creates a place in the cloud where PHP-based applications can be developed for the cloud. No more developing locally, then deploying into the cloud -- ZDC pushes both into the ether.

  • First look: Amazon RDS gives you a MySQL server in the cloud

    By Rick Grehan | 08 December, 2009 22:11

    Amazon's Relational Database Service (RDS) creates a MySQL database server in the cloud.

  • Cloud control systems tame the ether

    By Rick Grehan | 03 July, 2009 03:56

    Signifying a formless haze of computing power and storage that is somewhere "out there," computerdom's current buzzword is as difficult to get one's arms around as a real cloud. A seemingly limitless pool of processors and memory and disk space, and you just scoop out what you need. Sounds great, doesn't it?

  • Diving deep into Amazon Web Services

    By Rick Grehan | 14 August, 2008 08:43

    Amazon's Web Services (AWS) are based on a simple concept: Amazon has built a globe-spanning hardware and software infrastructure that supports the company's Internet business, so why not modularize components of that infrastructure and rent them? It is akin to a large construction company in the business of building interstate highways hiring out its equipment and expertise for jobs such as putting in a side road, paving a supermarket parking lot, repairing a culvert, or just digging a backyard swimming pool.

  • Hooking your apps into Amazon Web Services

    By Rick Grehan | 14 August, 2008 08:43

    Connecting your application into the Amazon Web Services (AWS) isn't complicated, particularly if you've done Web service programming on other projects.

  • .Net comes to WebSphere Portal

    By Rick Grehan | 09 May, 2008 10:08

    In the beginning, Mainsoft released Visual MainWin for Java EE, which compiled .Net CIL (Common Intermediate Language) code into Java bytecode. As technically fascinating as that was, on its own it provided limited traction. Much of Microsoft's attractiveness to the enterprise goes beyond its .Net languages and runtime frameworks. It is Microsoft's enterprise applications such as SharePoint and SQL Server that -- for many enterprise programmers -- make the .Net environment worth using. A tool that simply moves .Net code into Java moves that code out of reach of Microsoft's enterprise applications.

  • LISA iTKO 4 brings high quality to Web service testing QA

    By Rick Grehan | 14 March, 2008 09:04

    If you believe the documentation, the white papers, and the news releases, iTKO's recently released LISA 4 is an SOA testing tool. That descriptor, however, is modesty riding on the back of the still trendy acronym "SOA" because LISA goes well beyond testing what are typically understood to be SOA components: Under one roof, it houses the abilities to test Web and Java applications, the ESB (enterprise service bus), JMS (Java Message Service) systems, EJBs, databases, combinations of the above, and -- oh yes -- Web services.

  • Inside Google's mobile future

    By Rick Grehan | 28 February, 2008 07:06

    Android is Google's foray into the handheld OS realm. It follows a path trodden by -- among others -- Symbian's Quartz, the SavaJe operating system, and J2ME. In fact, one of Android's stated goals is to overcome some of J2ME's shortcomings. Whether or not Android succeeds, either at that specific goal, or in general, remains to be seen.
