  • Cut off wrong dependencies in your .NET code

    Patrick Smacchia advises developers to treat each namespace in an application as a component, and make sure there are no dependency cycles between your components. He claims that by abiding by this simple tenet, the structure of a large application can’t diverge to the monolithic block of spaghetti code base that seems to be the rule more than the exception in enterprise professional development.

    Data Modeling: Sample E-Commerce System with MongoDB

    The rich document capabilities and atomic operation guarantees in MongoDB makes it possible to model many different applications. Even rigorous requirements of conventional applications like e-commerce system are possible in a document database. This data model (i.e. "schema design,") is useful for developing applications around any restricted resource system, not just e-commerce systems.

  • CAP Twelve Years Later: How the "Rules" Have Changed

    The CAP theorem asserts that any networked shared-data system can have only two of three desirable properties (Consistency, Availability and Partition Tolerance). In this IEEE article, author Eric Brewer discusses how designers can optimize consistency and availability by explicitly handling partitions, thereby achieving some trade-off of all three.
