CRC Cards Tutorial - 0 views

  • 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..
    • Ahmed Mansour
       
      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.

XML Syntax - 0 views

  • XML Stores New Line as LF In Windows applications, a new line is normally stored as a pair of characters: carriage return (CR) and line feed (LF). The character pair bears some resemblance to the typewriter actions of setting a new line. In Unix applications, a new line is normally stored as a LF character. Macintosh applications use only a CR character to store a new line.

  • Authorisation Username:not present If you have "logged in" to a web site, your username appears here. Note that this only applies to web sites which use proper HTTP authentication - typically, a "login" window pops up and you get three chances to enter your username and password, otherwise you see a page which says "Authentication Required" or similar.  It doesn't apply to web sites where the "login" is a separate page. It's also possible to supply the username and password in the URL you tell your browser to visit - for example, http://user:password@www.example.com/.  In that case, the username would appear here too.

  • Dynamic programming problems are to be solved with tabular methods
    • Ahmed Mansour
       
      Dynamic programming, like the divide-and-conquer method, solves problems by combining the solutions to subproblems. ("Programming" in this context refers to a tabular method, not to writing computer code) y3ney 3bara 3n 2nene bn2sem el problem el kbirr le shwit probelsm so3'ira .. we ne solve el problems deh we ngma el yab2a dh 7l lel problem el kbira :D;d see introduction to algorithms book . chapter 15
  • breadth-first search
    • Ahmed Mansour
       
      In graph theory, breadth-first search (BFS) is a graph search algorithm that begins at the root node and explores all the neighboring nodes. Then for each of those nearest nodes, it explores their unexplored neighbor nodes, and so on, until it finds the goal. ya3ney be el 3arby keda lw ana 3ndy tree maslan we el tree dh bettkwen mn shwit levels 3ady gedan.. lama hagey 23mel search 3la node mo3ina fi el tree deh hamsk el tree mn el root bet3ha ely hwa level 0 we habda2 2mshy level by level y3ney hanzl 3la el level 1 we hakaz le 3'it mal2y el node bet3ty ,,,, see this ,, it's a tutorial show how BFS algorithm is work!! http://www.personal.kent.edu/~rmuhamma/Algorithms/MyAlgorithms/GraphAlgor/breadthSearch.htm

What is Domain Name Resolution - 0 views

  • What is Domain Name Resolution Introduction When using the Internet most people connect to web sites, ftp servers or other Internet servers by connecting to a domain name, as in www.bleepingcomputer.com. Internet applications, though, do not communicate via domain names, but rather using IP addresses, such as 192.168.1.1. Therefore when you type a domain name in your program that you wish to connect to, your application must first convert it to an IP address that it will use to connect to. The way these hostnames are resolved to their mapped IP address is called Domain Name Resolution. On almost all operating systems whether they be Apple, Linux, Unix, Netware, or Windows the majority of resolutions from domain names to IP addresses are done through a procedure called DNS.
