This chapter introduces the concept of software growth environments to support sustainable long term evolution of web-based application systems. A multi-agent prototype system is designed and implemented with emphasis on software testing. In this environment, software tools are agents that cooperate effectively with each other and human testers through communications at a high level of abstraction. New tools can be integrated into the system with maximal flexibility. These are achieved through the design and utilisation of an ontology of software testing that represents the knowledge of softwareengineering and codifies the knowledge for computer processing as the contents of an agent communication language. The ontology is represented in UML at a high level of abstraction so that it can be validated by human experts. It is also codified in XML for computer processing to achieve the required flexibility and extendibility.
AIM: The student is introduced to a modern C++ Rapid Application Development Tool for Win32 with the pur- pose of creating a human interface for pre-engineered C and assembly applications.

The software projects in ISBSG release 7 data came from 20 different countries. Figure 2 illustrates the major data-contributing countries. The top three known contri- buting countries were the United States, Australia and Canada. Over 97% of the projects were completed be- tween the years 1989-2001. Most of the projects (about 50%) were completed between the years 1999-2001. Figure 3 illustrates the data quality rating of the ISBSG release 7 data on the 1238 projects, and Figure 4 illus- trates the industry type distribution for the 1238 projects. The ISBSG data set included data on integrated CASE tools, programming languages, development type, de- velopment platform, elapsed time, productivity and team size. Of the total 1238 software projects, only 138 pro- jects had complete data on all five independent and de- pendent variables for investigating elapsed time and pro- ductivity. For the elapsed time and productivity model, we used all 138 projects, respectively, in our analysis.
Component-Based Development (CBD) has not redeemed its promises of reuse and flexibility. Reuse is inhibited due to problems such as component retrieval, architectural mismatch, and application specificness. Component-based systems are flexible in the sense that components can be replaced and fine-tuned, but only under the assumption that the software architecture remains stable during the system's lifetime. In this paper, we argue that systems composed of components should be generated from functional and nonfunctional requirements rather than being composed out of existing or newly developed components. We propose a generation technique that is based on two pillars: Feature-Solution (FS) graphs and top-down component composition. A FS- graph captures architectural knowledge in which requirements are connected to solution fragments. This knowledge is used to compose component-based systems. The starting point is a reference architecture that addresses functionality concerns. This reference architecture is then stepwise required to cater for non- functional requirements using the knowledge captured in a FS-graph. These requirements are the architecture-level counterpart of aspect weaving as found in Aspect- Oriented Programming (AOP).
Electronic commerce, commonly known as e- commerce or e-Commerce, consists of buying and selling of products or services over electronic systems, such as, the Internet and other computer networks. 1 It can be broadly stated that e-commerce encompasses all commercial transactions that are conducted electronically. 2 It can be further defined as, any business transactions that are carried out electronically with a view to improving the efficiency and effectiveness of market and business processes. 3 e-Commerce follows the same basic principles as traditional commerce, i.e., buyers and sellers come together to swap commodities for money. But rather than conducting business in the traditional way in shopping stores or through mail order catalogs and telephone operators — in e-Commerce buyers and sellers transact business over networked computers.
Retention between year 1 and year 2 varied little from 2007/08 to 2010/11, ranging from 82.9% to 85.5%. However, the retention of the 2011/12 was notably weaker at 73.4%. By contrast, retention of SoftwareEngineering students has steadily decreased from 2007/08 (98.2%) to 2009/10 (97.4%), followed by sudden drops for the 2010/11 and 2011/12 cohorts (92.4% and 88.5%, respectively). The reason for the apparent jump in the number of 'not retained' students in 2011/12 (265/16.65%) is most likely the result of the implementation of new progression rules for first-year engineering students together with a new streaming schedule for some students. Additional data for subsequent years is needed to fully assess whether the reported figure indicates a trend or is an anomaly.
Use cases may be structured hierarchically – but care should be taken not to functionally decompose the use cases. Use cases are not functions, they use functions. There is no “golden rule” with regard to the number of use cases needed to describe a system. Experience shows that for large systems, typically 6 to 24 use cases may be defined at the top level. At the lowest level a use case should be described by at least 5, with a maximum of 25 essential use case scenarios. At this stage, emphasis is put on the identification of “sunny day” use cases, assuming an error/fail free system behavior. Exception scenarios will be identified at a later stage (=> system functional analysis) through model execution. If more than 5 error/fail scenarios are found for a use case, they should be grouped in a separate exception use case, which are then linked to the “sunny day” use case via an include or extend dependency.
Newly admitted students are strongly encouraged to meet the requirement very early in their program (fall term of first year for students starting in September or winter term of first year for students starting in January) in order to avoid the risk of delayed graduation should remedial work prove necessary. The Engineering Writing Test is especially designed to address the writing skills typically demanded of engineers. Students who are required to take ESL courses should meet the writing skills requirements in the term following completion of their ESL courses.
VE challenges the conventional rule for operating an organization. They do so by accomplishing tasks traditionally meant for an organization much bigger, better resourced, and financially stable. A company having the technical capability, one with the right human skill set, the other with the solution, may come together to create a VE. For example, the current situation within the construction industry is that many projects are one-of-a-kind and involve the coordination of practitioners such as designers, engineers and suppliers. A typical construction project consists of a number of organizations and teams that are brought together for the duration of that particular project to form a so- called "virtual enterprise". This enterprise often contains units that are in different physical locations and use different computer platforms and have a need to work collaboratively and to share the same project data (Faraj et al, 2000). Some of the key benefits include but are not limited to:
Majority of software developers in the industry are simply graduated in different disciplines related to informatics: computerengineering (CE)/science (CS), information system engineering (ISE), and softwareengineering (SE). All these software engineers will be the IT managers and they will have responsibilities of managing big tasks, teams and handling the complex projects. However, most of them do not have any practical training for project management. They gain the knowledge of project management only by experience, which certainly may not be sufficient to be a successful team leader.
According to , there are two types of detection techniques, which can respond to intrusion: active or passive. In a passive technique, the system is configured to only monitor and analyze the network traffic activity and then alert an operator of potential vulnerabilities and attacks. However, such a response cannot perform any protective or corrective functions by itself. The passive detection technique is advantageous because of its ability to be easily and rapidly deployed. In addition, these systems are normally not susceptible to attacks themselves. However, the passive system does not reduce the damage caused by the intrusion or even attempt to defend against the attacker. It only notifies the authority concerned which, in turn, will confirm the attack and then take the measures required .
The interviewees mention that almost exclusively more senior people do requirements activities. Some interviewees argue that experience is necessary. One interviewee expects credibility and presence from somebody doing requirements activities. These characteristics are considered to be reserved to people more mature than most graduates are. In businesses where requirements activities do not involve direct contact with customers the argument is that people must have insight and knowledge about the existing software, which is described as experience.
naval Air station in st. mary’s county. This expansion created a demand for higher education opportunities for employees being relocated to this area. in response, maryland created the southern maryland higher edu- cation center (smhec) to give colleges and universi- ties the opportunity to offer needed programs. epp and ApL responded to this need by offering programs in 1997. currently, the systemsengineering and Technical management programs are offered at this location.
This is the first course that students encounter in the systems and softwareengineering stream where we don’t simply concentrate on software issues. Students taking this course have already taken courses in program and data structure design, introductory softwareengineering and software design. In introducing the course, we thought carefully about what we were trying to achieve and came to the conclusion that the fundamental goal of the course was what Checkland  calls systems thinking. That is, we wanted to expand the horizons of students so that they thought of problem-solving in systems and not just in software terms. When faced with a problem situation, we wanted them to be able to think critically about the problem as well as the possible solutions to the problem.
