The forgotten Milk

Recently, I made clean the knowledge structure on computer language. Maybe it is helpful for some new guys on this field. There are six levels totally.  On each level, I just put some words there. But each word has rich and deep content. Since now, I will dive deep into them.

6th, Top:

• VM, compiler
• Performance Tuning
  ——————————————————————————————
  5th, High Level:
• Algorithms
• DesignPattern(Singleton, Observer, Producer, Consumer, Adapter, MVC, Command, Strategy, Composite)
• Framework(J2EE,Struts,Spring,Hibernate,Zend,CakePHP…)
  ——————————————————————————————
  4th, IDE:
• debug
• unittest
• team
• SCM
  ——————————————————————————————
  3rd, Extension:
• Log
• Error handle
• Math
• RE
• IO(Stream, Serializing, Buffer, Channel, Compression) -> Filesystem
• Network(Socket,Mail,FTP, News, LDAP)
• MultiMedia(Image,Sound,Movie)
• Serial,Parallel
• GUI(AWT,Swing,2D,3D)
• Internationalization, Localization
• Database(Connection, Query, Result, RowSet, Transaction)
• XML(DOM, SAX, DTD, XPath, XInclude, Validate, XSL/XSLT, WebService[RPC,SOAP], Data Binding, XLink, XPointer, Schema)
• Distributed(RMI)
• Thread(Safe, Priority, Synchrony,Notification, Atomic, ThreadGroup, ThreadPool, Time)
• Invoke Other Language/Native
• CGI(WebServer, AppServer, Cookie, Session, Embed, Authentication, Request, Response, Header, Tag, MVC, ORM, Template)
• Security(Encryption,Decryption,SSL,GPG)
  ——————————————————————————————
  2nd, Feature:
• DataStructure(list,map,stack,iterator,tree, queue, vector, dictionary, table, bitset, properties, Enum)
• OO(Polymorphism, Override, Inheritance, Clone) (instanceof, compare, serialize, toString) (Nested, Member, Method, Constructor, Destructor, Finalize, This, Instance, Static, Abstract, Interface, Casting, Final, Anonymous, Reflection, Generics)
  ——————————————————————————————
  1st, Syntax:
• Variable
• Operator
• Keyword
• Datatype(number,boolean, character, array,date,string)
• Control Flow(if else, while for, break, continue, case, return, assert)
• Comment, Doc(Annotation)
• Function(Reuse)
• import, include
