  • What are the advantages of compiled versus interpreted languages?

    • As compiled languages tend to result in marginally faster applications,
    • there are many reasons for using interpreted languages rather than compiled ones. The primary reasons are that interpreted languages generally allow for faster development, easier updating and easier debugging with only a marginal increase in processing time. Interpreted languages also tend to be more portable, able to be run without being modified for different computing environments.

  • interpreted - a definition from Whatis.com

    • An interpreted program, sometimes called a script, is a program whose instructions are actually a logically sequenced series of operating system commands, handled one at a time by a command interpreter. In turn, the command interpreter requests services from the operating system
    • The writer of the interpreted program need not be concerned by low-level storage management considerations.

  • What is Java best suited for?

    • Because the Java programming language was designed to effectively be run on any computing platform, Java has been used in every situation where a software developer has wished to write one application and have it run on a variety of different types of computing platforms, whether personal computers, servers, palm-top computers, mobile phones or the computers embedded in machines such as automobiles.
    • The problem with this approach is that, in the world of computing, one size does not fit all.

  • Interpreted vs Compiled

    • interpreted code can be run directly from the text file it is stored in, while compiled code requires an extra step of reading that text file and turning it into a file that the computer can run.
    • A passable analogy might be that of working with a coworker from another country who doesn't understand your language. You need to give that person a set of tasks to perform but you need a third party to translate. In the "interpreted" scenario, you would tell the translator the first task, who then would translate it for your coworker, who would execute the task and then wait for your next command.

  • Interpreted Language

    • The term "InterpretedLanguage" is archaic, and referred to a language that was evaluated as the programmer typed it instead of being compiled into a single monolithic "executable". Some early languages (Pascal and many early implementations of Basic, for example) could be either compiled or interpreted according to the desire of the programmer and system administrator. While the term is still used informally in some circles, most professionals agree that advances in both compiler and interpreter design and implementation have made the distinction moot in any rigorous sense.

  • Multi-tier Architecture: Know-how

    • High-level Analysis of the
      Architecture
    • emerged in the 1990s to
      overcome the limitations of the two-tier architecture the third tier (middle
      tier server) is between the user interface (client) and the data management
      (server) components. This middle tier provides process management where business
      logic and rules are executed and can accommodate hundreds of users (as compared
      to only 100 users with the two tier architecture) by providing functions
      such as queuing, application execution, and database staging.

  • Multitiered Architectures (Linktionary term)

    • Multitiered architectures are software models (and hardware models, as discussed later) that extend the basic two-tiered client/server model to three tiers. In the basic two-tiered client/server model, the client requests services and the server provides services. There are software interfaces on the client and the server side that connect with one another to handle these interactions.
    • However, the two-tiered model has some drawbacks. Both clients and servers run a portion of the application logic, with the servers handling the loads of back-end data management. This requires that client software be installed, managed, and updated on a potentially large number of systems. The two-tier model tends to move large numbers of records across the network to clients that may not always be optimized to handle them. The model is not efficient in distributed wide area network environments like the Internet. For example, a Web client may be a hand-held system with limited memory and processing power. It cannot be relied on to handle front-end processing tasks.
