software tools available to help software engineers to do the work, either forward engineering or reverse engineering .
Forward Engineering is a traditional process of high-level abstraction, logic and independence design for a system physical structure implementation.
Reverse engineering is the analysis and processing of an existing system to identify its components and their intrinsic relations, so as to build a framework of a system with high-level abstraction. In mos

(Dependency)
definition: for two relatively independent objects, when one object is responsible for constructing an instance of another object, or depending on the service of another object, the two objects are primarily dependencies.
performance: dependencies are expressed in
local variables ,
the parameters of methods , and calls to
static methods .
Example: If you're going to screw the screws, do you want to use (ie rely on) a screwdriver (screwdriver)
.
Constraints
Specifies one or more rules to satisfy for some classes and interfaces, using free-text identifiers enclosed in curly braces in UML.
Package
Packages in UML correspond directly to packages in Java to represent hierarchies and organizational content. Relationship of Class
This essay is well written, in PHP to explain the UML (or vice versa) can be said to be an innovation, through this article, I also found a good station: www.phppatterns.com. The translation of the UML terms comes from the UML User Guide (the Unified Modeling Language user Guide) that I am looking at.

Because the package contains classes, you can represent the relationship between packages and packages based on the relationships between the classes in those packages.Figure DAssociation (Association)A structured relationship between entities in a UML class diagram relationship indicates that the objects are inter

7: instance
An instance is a running entity with an identity, that is, it can be differentiated from other running entities. It has a value at any time, and the operation value on the instance will also be changed.

The aggregation relationship is also implemented using instance variables. There is no association or aggregation from the Java syntax.
Combinatorial (composition) relationship (composition): Also a special case of association, he embodies a kind of contains-a relationship, which is stronger than aggregation, also known as strong aggregation; he also embodies the relationship between the whole and the parts
declared in the interface. In UML, the implementation relationship between a class and an interface is represented by a dashed line with a hollow triangle.
