shared by Islam TeCNo on 08 Jun 09 - Cached
  • A database is a structured collection of records or data that is stored in a computer system. The structure is achieved by organizing the data according to a database model. The model in most common use today is the relational model. Other models such as the hierarchical model and the network model use a more explicit representation of relationships

  • Object Oriented Analysis and Design using CRC Cards
  • A CRC cards is an index card that is use to represent the responsibilities of classes and the interaction between the classes. CRC cards are an informal approach to object oriented modeling. The cards are created through scenarios, based on the system requirements, that model the behavior of the system. The name CRC comes from Class, Responsibilities, and Collaborators which the creators found to be the essential dimensions of object oriented modeling.

      One of the most popular methods for identifying and categorizing classes is to use class-responsibility-collaboration cards (CRC). Each CRC card represents a single class's data attributes, responsibilities, and collaborations. source : Thought Process Book..

      You need to create three sections on each card: - The name of the class - The responsibilities of the class - The collaborations of the class
  • Why uses CRC cards?
  • ...4 more annotations...
  • They are portable... No computers are required so they can be used anywhere. Even away from the office. The allow the participants to experience first hand how the system will work. No computer tool can replace the interaction that happens by physically picking up the cards and playing the roll of that object... The are a useful tool for teaching people the object-oriented paradigm. They can be used as a methodology them selves or as a front end to a more formal methodology such as Booch, Wirfs-Brock, Jacobson, etc.

    TCP/IP protocol based questions for gate computer science exam Q1.What is the difference between transport and session layer of OSI model. Answer: OSI Model Transport Layer The transport layer uses the services provided by the network layer, such as best path selection and logical addressing, to provide end-to-end communication between source and destination. • The transport -layer data stream is a logical connection between the endpoints of a network. • End-to-end control is provided by sliding windows and reliability in sequencing numbers and acknowledgments. The transport layer regulates information flow to ensure end-to-end connectivity between host applications reliably and accurately. • The TCP/ IP protocol of Layer 4 (t transport t layer ) has two protocols. They are TCP and UDP. The transport layer accepts data from the session layer and segments the data for transport across the network. Generally, the transport layer is responsible for making sure that the data is delivered error-free and in the proper sequence. Flow control generally occurs at the transport layer. OSI Model Session Layer The session layer establishes, manages, and terminates communication sessions. Communication sessions consist of service requests and service responses that occur between applications located on different network devices. These requests and responses are coordinated by protocols implemented at the session layer. The session layer establishes, manages, and terminates sessions between applications Functions of the session layer and the different processes that occur as data packets travel through this layer. More specifically, you learned that Communication sessions consist of mini-conversations that occur between applications located on different network devices. Requests and responses are coordinated by protocols implemented at the session layer. • The session layer decides whether to use two-way simultaneous communication or two-way alternate communicati

  • Model–view–controller (MVC) is an architectural pattern used in software engineering. Successful use of the pattern isolates business logic from user interface considerations, resulting in an application where it is easier to modify either the visual appearance of the application or the underlying business rules without affecting the other. In MVC, the model represents the information (the data) of the application; the view corresponds to elements of the user interface such as text, checkbox items, and so forth; and the controller manages the communication of data and the business rules used to manipulate the data to and from the model.

  • MVC is often seen in web applications, where the view is the actual HTML or XHTML page, and the controller is the code that gathers dynamic data and generates the content within the HTML or XHTML. Finally, the model is represented by the actual content, which is often stored in a database or in XML nodes, and the business rules that transform that content based on user actions.

Flocking (behavior) - Wikipedia, the free encyclopedia - 0 views

  • Flocking behavior is the behavior exhibited when a group of birds, called a flock, are foraging or in flight. There are parallels with the shoaling behavior of fish, or the swarming behavior of insects. Computer simulations and mathematical models which have been developed to emulate the flocking behaviors of birds can generally be applied also to the "flocking" behavior of other species. As a result, the term "flocking" is sometimes applied, in computer science, to species other than birds. This article is about the modelling of flocking behavior. From the perceptive of the mathematical modeller, "flocking" is the collective motion of a large number of self-propelled entities and is a collective animal behavior exhibited by many living beings such as birds, fish, bacteria, and insects.[1] It is considered an emergent behaviour arising from simple rules that are followed by individuals and does not involve any central coordination. Flocking behavior was first simulated on a computer in 1986 by Craig Reynolds with his simulation program, Boids. This program simulates simple agents (boids) that are allowed to move according to a set of basic rules. The result is akin to a flock of birds, a school of fish, or a swarm of insects.

Belief-Desire-Intention software model - Wikipedia, the free encyclopedia - 0 views

en.wikipedia.org/...BDI_software_agent

shared by Islam TeCNo on 10 Jun 09 - Cached
  • The Belief-Desire-Intention (BDI) software model (usually referred to simply, but ambiguously, as BDI) is a software model developed for programming intelligent agents. Superficially characterized by the implementation of an agent's beliefs, desires and intentions, it actually uses these concepts to solve a particular problem in agent programming. In essence, it provides a mechanism for separating the activity of selecting a plan (from a plan library) from the execution of currently active plans. Consequently, BDI agents are able to balance the time spent on deliberating about plans (choosing what to do) and executing those plans (doing it). A third activity, creating the plans in the first place (planning), is not within the scope of the model, and is left to the system designer and programmer.

  • Artificial life (commonly Alife or alife) is a field of study and an associated art form which examine systems related to life, its processes, and its evolution through simulations using computer models, robotics, and biochemistry.[1] There are three main kinds of alife[2], named for their approaches: soft[3], from software; hard[4], from hardware; and wet, from biochemistry. Artificial life imitates traditional biology by trying to recreate biological phenomena.[5] The term "artificial life" is often used to specifically refer to soft alife
  • The modeling philosophy of alife strongly differs from traditional modeling, by studying not only “life-as-we-know-it”, but also “life-as-it-might-be” [7].

en.wikipedia.org/Scalability

shared by Islam TeCNo on 16 Jun 09 - Cached
  • In telecommunications and software engineering, scalability is a desirable property of a system, a network, or a process, which indicates its ability to either handle growing amounts of work in a graceful manner, or to be readily enlarged.[1] For example, it can refer to the capability of a system to increase total throughput under an increased load when resources (typically hardware) are added. An analogous meaning is implied when the word is used in a commercial context, where scalability of a company implies that the underlying business model offers the potential for economic growth within the company.

      In Web applications client data are saved on the server (then the server memory is decreased that decreases the scalability - الإستيعاب-) So removing the client data improvers scalability becuase it saves server memory
