Abstract. Recent frameworks employ the strategy to define a specific metadata schema for applications to use in their classes and programming elements, enabling framework behavior customization. Despite this technique is being widely used, there are not models, design patterns or development guidelines that aim to help in the creation of this kind of framework. This thesis proposes a conceptual model for metadata-based frameworks that has the aim to identify appropriate solutions for its internal structure and scenarios where it is suitable for. As a result, software architects and framework developers with this conceptual model should be able to identify situations where the metadata usage is appropriate and to design suitable solutions that provides flexibility in metadata reading and processing.

1. Context
A framework is a set of classes that supports reuse at larger granularity. It defines an object-oriented abstract design for a particular kind of application which enables not only source code reuse, but also design reuse [Johnson & Foote, 1988]. The framework abstract structure can be filled with classes from its own library or application-specific ones, providing flexibility for the developer to adapt its behavior to each application. Besides flexibility, a good framework also increases the team productivity and makes application maintenance easier [Fayad et al. 1999].
In the first frameworks, the application classes had to be compatible with the framework protocol usually by extending an abstract class or implementing an interface. The framework structures evolved and recent ones use introspection [Forman and Forman 2005] to access at runtime the ...

The first class stereotype is boundary class. The boundary class used to model interaction between the system's surroundings and its inner workings. The boundary class interaction is involves transforming, translating events and noting changes in the system presentation. This class also model the parts of the system that depend on its surroundings. There are also class’s uses to model the parts that are independent of the system's surroundings such as entity classes and control classes. With that, the changing of communication protocol (GUI) mean changing only the boundary classes, not the entity and control classes. The boundary class also use to clarify the system's boundaries. With that, this class make it easier to understand the system. This class also providing a good point of departure for identifying related services for aid d...

Before analyzing how my framework is influenced by my environment, there are a few internal factors.
For years, C++ (C Plus Plus) has dominated the business market place for many different companies and has allowed many computer programmers to obtain vast amounts of knowledge and experience since 1972 when it was first developed by Dennis Ritchie of AT&T Bell Laboratories (Lambert / Nance Page 16). It has been in use for almost thirty years – not to mention the years before when it’s precursor C was developed and commonly used also – and has made a great impact on the development of software for business’ across the world. It has become a second nature programming language to those that use it and have been forced to stay with C++.
When researching about design patterns in programming you instantly realize that they can be very useful in implementing a certain piece of code or just having it as a useful programming practice. Design patterns are created to solve common programming problems that keep on recurring in a certain context when designing a program. There are several types of design patterns that are all split into several groups. Some of these groups are Algorithm Strategy Patterns, Execution Patterns, Structural design patterns, Creational design patterns, Behavioral design patterns and Computational design patterns. Each of these sub groups of design patterns goes about solving a different type of problem. Design patterns can be beneficial because of the simple fact that they are solving programming problems that would usually surface when programming.
Reading patterns is a valid method of deducing information. Certain values or outcomes may be estimated with a variable degree of certainty depending on the amount of information one has about the context. While it is impossible to create ideas out of nothing, is not difficult to piece together a puzzle that is only missing one piece. Hume’s ideas are a good starting point in the discussion of non-empirical science but it is important to entertain other ideas as

The Unified Modeling Language is a standard language for specifying, visualizing, constructing, and documenting the artifacts of software systems, as well as for business modeling and other non-software systems. The key is to organize the design process in a way that clients, analysts, programmers and other involved in system development can understand and agree on. The UML provides the organization. The UML was released in 1997 as a method to diagram software design, by some of the best minds in object oriented analysis and design. It is by far the most exciting thin to happen to the software industry in recent years. Every other engineering discipline has a standard method of documentation. Electronic engineers have schematic diagrams; architects and mechanical engineers have blueprints and mechanical diagrams. The software industry now has UML.
HTML frameworks serve as a skeleton when designing websites. They are designed to be a way to quick build a page which is why I would often refer to them as templates. Not only do frameworks apply to pages, they can be used to code style sheets as well since frameworks are not something that needs to be complex. It is possible to have a library of them. An example would be if you wanted to have different style sheets for different occasions spread throughout different sites. Such a method can be used on regular pages such as if you were running a business and wanted to have a uniform product page. One good point about them is that they are easy to find as there are hundreds of them. There are many advantages and disadvantages to frameworks.
obect orientated programming has many advantages, one of these is the fact that the objects created : Jeffrey L. Popyack (2012) "can easily be reused in other programs." The Saylor Foundation also states that object orientated programming allows “Improved software-development productivity" and "Improved software maintainability” through the modular structure of the development.

Explain in around 600 words, citing any literature you have consulted, what is meant by these terms in relation of object-oriented software design, and explain how they relate to the design you developed in your group.
The Nature of Mathematics Mathematics relies on both logic and creativity, and it is pursued both for a variety of practical purposes and for its basic interest. The essence of mathematics lies in its beauty and its intellectual challenge. This essay is divided into three sections, which are patterns and relationships, mathematics, science and technology and mathematical inquiry. Firstly, Mathematics is the science of patterns and relationships. As a theoretical order, mathematics explores the possible relationships among abstractions without concern for whether those abstractions have counterparts in the real world.
