Transaction processing system

What is transaction? Today all the application we are using are based on Transaction processing  system from your e-banking toe railway booking this article  describes Transaction processing  system in detail  .In the normal course doing business there are many events which take place in transactions are events which involve two or more parties one being the business entity .transactions normally involve money worth. There are many transactions that occur in the business organizations and are taking phase on a continuous basis on all fronts in business entry. We  have transaction taking place in…Read more

What is mean by Integration Testing?

    Integration Testing:- Integration testing is a systematic testing for constructing the software architecture and conducting test to uncover error associated with interface. the objective is to take unit tested components and build a program structure that has been dictated by design. in case of non incremental integration, all component are combined in it . and The complete   program is tested as a whole. This result as a set of a error is encountered and correction is difficult because isolation of cause is complicated by vast expense of a entire program. In…Read more

What is The Need of Electronic Commerce

           Today, in every aspect of our day to day life  internet has become undivided part of our life .People work online, every day the bank system online checks mail online every day, even make friends and date online. So it’s only so it only makes sense that on line shopping has become an increasingly integral part of our society, exceeding $200 billion in sales in 2010 alone. The internet economy is booming E –commerce sales are expanding by leaps and bounds at a rate of 20% and 25%…Read more

Synchronization and Critical Section Problem

Synchronization    A cooperating process is one that can affect or be affected by other processes executing in the system. Cooperating processes can directly share a logical address space (that is, both code and data) or be allowed to share data only through files otherwise messages. The former case is achieved through the use of threads, discussed in this. Concurrent access to shared data may result in data inconsistency, however. In this we have discuss various mechanisms to ensure the orderly execution of cooperating processes that share a logical address space so that…Read more

Validation Testing

What is the validation testing? Explain alpha and beta testing? Validation testing begins at the culmination (climax) of integration testing when individual components have been exercised software is completely assembled as package and interfacing error have been uncovered and correct. Testing focuses on the user visible action and user recognizable output from system. Validation can be defined as that of the validation succeeds when software functions in a manner that can be reasonably expected by the customer. These are known all about the validation testing. There are some validation criteria these criteria are…Read more

Basics of Testing

Errors and Testing Humans make errors in the thoughts, in their actions, and in the products that might result from Their actions. Humans can make errors in a field. Ex: observation, similarly even in software development. Example: An instructor administers a test to determine how well the students have understood what the instructor wanted to convey a tennis coach administers a test to determine how well the understudy makes a serve. Errors, Faults and Failures Error:  This is occurs in the process of writing a program Fault: this is a manifestation of one or…Read more

The Process Model

This article states that functioning of process model and various process model used in software engineering .This article explain use of this model in software development life cycle (SDLC) in simple lucid language.  The major and commonly used process models should be adapted for uses by a software project team. To achieve this, process technology tools have been developed which helps software development organizations to 1. Analyze current process 2. To organize their work task or activities. 3. Keep control monitor and progress 4. help to reduce development time and cost There is…Read more

Buy Website Traffic: How to succeed in getting targeted traffic

Running a website for business is not an easy task. Making a targeted traffic to visit your website is tricky. With simple solutions it is possible to generate a lot of traffic. While considering these solutions you must be aware of differences between dense traffic and optimal traffic. The paid PPC campaign solutions work best. You can think of newsletters and marketing websites for getting visitors. But a big wallet and careful planning is essential when you are considering it. While purchasing traffic clicks in bulk sounds good, but in reality it’s the…Read more

Incremental Process Models

   Initially in the software development, there are some situations in which requirement collected in the beginning are reasonably well-defined But at same time overall scope of the development effort stops a purely linear process. There may be a forceful need to provide a limited set of software functionality to users very fast and then refine and expand on that functionality after software releases.   Fig 1.3 phases of incremental model and working   In these types of situations a process model that is designed to produce the software is incremental model. The…Read more

The Spiral Model

       Boehm has proposed the spiral model .Spiral models software process is combination of an iterative nature of prototyping and controlled and systematic aspects of the traditional waterfall model. This model is able to produce rapid development in more complicated version of software. IN SPIRAL MODEL, software development takes place in a series of developed releases. In initial stage iterations, the release or model might be presented on a paper or may be a prototype model. These are kind of designing stages. In the later stages when completing stages comes software…Read more
