fstab

The fstab (/etc/fstab) (or file systems table) file is a system configuration file commonly found on Unix systems. It is part of the util-linux package. The fstab file typically lists all available disks and disk partitions, and indicates how they are to be initialized or otherwise integrated into the overall system’s file system. fstab is still used for basic system configuration, notably of a system’s main hard drive and startup file system, but for other uses has been superseded in recent years by automatic mounting.

The fstab file is most commonly used by the mount command, which reads the fstab file to determine which options should be used when mounting the specified device. It is the duty of the system administrator to properly create and maintain this file.

The file has other names on some versions of Unix; for instance, it is /etc/vfstab on Solaris. Continue reading →

What is Software Architecture?

Software application architecture is the process of defining a structured solution that meets all of the technical and operational requirements, while optimizing common quality attributes such as performance, security, and manageability. It involves a series of decisions based on a wide range of factors, and each of these decisions can have considerable impact on the quality, performance, maintainability, and overall success of the application.

Philippe Kruchten, Grady Booch, Kurt Bittner, and Rich Reitman derived and refined a definition of architecture based on work by Mary Shaw and David Garlan (Shaw and Garlan 1996). Their definition is:

Software design vs software architecture

Software Engineering

Architecture usually deals with what (is done) and where (it is done), but on the other hand, Design deals how(it is done).

Architecture is Highest level of abstraction of system, kind of skeleton. MVC, MOVE, 3-Tier, Service Oriented Architecture are architectural patterns exactly like different design patterns.

Software Design is about designing individual class/ modules / components and their responsibilities and functions.

  • An entirely re-written event-driven MVC layer
  • Components practice dependency injection, supported by our Service Locator and DiC components
  • A powerful module management system
  • An EventManager, for writing event-driven systems, as well as for creating cut points in your software for introducing cross-cutting concerns.
  • A new view layer, architected around analyzing the request and generating a suitable response, be it plain old HTML, or Atom feeds or JSON.
