Software Safety and Hazard Analysis

Rashmi — Thu, 25 Feb 2010 09:16:43 +0000

Software safety and hazard analysis are SQA activities that focus on the identification and assessment of potential hazards that may impact software negatively and cause entire system to fail. If hazards can be identified early in the software engineering process software design features can be specified that will either eliminate or control potential hazards. A [...]

Cost of Quality

Rashmi — Thu, 25 Feb 2010 09:09:26 +0000

Cost of Quality includes all codes incurred in the pursuit of quality or in performing quality related activities. Cost of quality studies are conducted to provide a base line for the current cost of quality, to identify opportunities for reducing the cost of quality, and to provide a normalized basis of comparison. The basis of [...]

QUALITY CONTROL (QC)

Rashmi — Thu, 25 Feb 2010 09:04:28 +0000

QC is the series of inspections,reviews, and tests used throughout the development life cycle to ensure that each work product meets the requirements placed upon it. QC includes a feedback loop to the process that created the work product. The combination of measurement and feedback allows us to tune part of the manufacturing process QC [...]

QUALITY OF CONFORMANCE

Rashmi — Thu, 25 Feb 2010 09:00:30 +0000

Quality of conformance is the degree to which the design specifications are followed during manufacturing. Again, the greater the degree of conformance, the higher the level of quality of conformance. In software development, quality of design encompasses requirements,specifications and design of the system. The requirements must be gathered formally and there should not be any [...]

QUALITY CONCEPTS

Rashmi — Thu, 25 Feb 2010 08:42:18 +0000

Its Quality concepts 1. Quality 2. Quality control 3. Quality assurance 4. Cost of quality The American heritage dictionary defines quality as “a characteristic or attribute of something”. As an attribute of an item quality refers to measurable characteristic-things, which we are able to compare to known standards such as length,color,electrical properties, and malleability and [...]

DATA MINING FOR FINANCIAL DATA ANALYSIS

Rashmi — Thu, 25 Feb 2010 08:38:49 +0000

Most banks and financial institutions offer a wide variety of banking services (for example saving balance checking, individual transactions), credit (such as loans, mortgage) and investment services (mutual funds). Some also offer insurance services and stock investment services. Financial data collected in the banking and financial i9ndustry are often relatively complete,reliable and of high quality,which [...]

Requirements for Clustering in Data Mining

Rashmi — Thu, 25 Feb 2010 08:32:31 +0000

Clustering is a challenging and interested field potential applications pose their own special requirements. The following are typical requirements of clustering in data mining: 1. Scalability: Many clustering algorithms work well on small data sets containing fewer than 200 data objects. However, a large database may contain millions of objects. Clustering on a sample of [...]

CLUSTERING IN DATA MINING

Rashmi — Thu, 25 Feb 2010 08:28:29 +0000

Clustering is a division of data into groups of similar objects. Each group, called cluster, consists of objects that are similar between themselves and dissimilar to objects of other groups. Representing data by fewer clusters necessarily loses certain fine details (akin to lossy data compression), but achieves simplification. It represents many data objects by few [...]

Dynamic Linking

Rashmi — Wed, 24 Feb 2010 17:42:44 +0000

Dynamic linking is the process by which an application in the Windows environment is able to link to library functions at run time. Ina standard C# program, various built-in functions, which are invoked by the program, are resolved to a library during compilation. The library contains code for these functions. The compiler identifies the library [...]

Event-Driven Programming

Rashmi — Wed, 24 Feb 2010 17:38:53 +0000

Windows enables you to execute programs by using a mouse. When you click on a control, an event is generated. An event is an action performed by the user. Windows generates messages in response to each event performed by the user. These messages are sent to the application and, depending on the messages received, the [...]
