Q4. Explain the various activities involved in Software Reengineering process model. A4. Software Reengineering A program has served the business needs of a company. During that time it has been corrected, adapted and enhanced many times. for instance the application is unstable because but every time a be replaced is attempted, unexpected and serious side effects can occur. Un-maintainable software is not a new problem. In fact, a software maintenance team has generated the broadening…

Summary of Findings •High quality public transportation (convenient, comfortable, fast rail and bus transport) and transit oriented development (walkable, mixed-use communities located around transit stations) tend to affect travel activity in ways that provide large health benefits, including reduced traffic crashes and pollution emissions, increased physical fitness, improved mental health, improved basic access to medical care and healthy food and increased affordability which reduces…

Interfacing the Interface As cities evolve, the way that citizens interact with them through interfaces evolves as well. The modern smart city usually involves incredibly complex technological interfaces that provide citizens with constant information about their surroundings in real time. In her journal titled “Interfacing Urban Intelligence,” Shannon Mattern discusses these interfaces and the image they present about the values of the city its citizens. She argues that since the citizens…

1. Why do the photographers use a polarizing filter when photographing the waterfall? The photographer uses a polarizing filter to saturate the colors and to remove glare that can come from the water and sun. 2. Why does Gardner suggest trying a horizontal photograph for a waterfall? He suggests horizontal photos for waterfalls because it allows for a better background around the waterfall and because of how unpredictable the composition of the photo can turn out to be. 3. How did the…

State projection of Layer V of the Primary Somatosensory Cortex (1pt) Layer V projects to the dorsal column nuclei, as well as to the dorsal horn of the spinal cord; and to the striatum and brain stem in general. 15. What is the pathway of the projections of the Secondary Somatosensory Cortex (SII)? (1pts) Projects to the Insula which then projects to amygdala…

option in handling and analyzing structural data, they suffer from a variety of problems including performance and scalability issues when it comes to big data. To increase the performance of DBMS for big data storage needs, partitioning the data across several sites and paying big license fees for enterprise SQL DBMS might be the two possible options (Stonebraker, 2010), however they are not even without disadvantages such as inflexible data…

The rule for first normal form (1NF) is a table in which the intersection of every column and record contains only one value. In other words a table that contains more than one atomic value in the intersection of one or more column for one or more records is not in 1NF. The non 1NF table can be converted to 1NF by restructuring original table by removing the column with the multi-values along with a copy of the primary key to create a new table. See Figure 8.4 for an example of this approach.…

These 3 set of people forms an equal partnership to drive the project in a collaborative manner. XP implement a simple but effective environment enabling all concern members to achieve solution and maximize productivity. The main idea is that the team rallies around the problem or case for the solution. Such development practice qualifies XP to be an agile method of software development. Citing Don well (1999, 2000, 2001, 2004, 2009) Extreme Programming improves a software project in five…
