E-commerce (or electronic commerce) is any business transaction whose price or essential terms were negotiated over an online system such as an Internet, Extranet, Electronic Data Interchange network, or electronic mail system. It does not include transactions negotiated via facsimile machine or switched telephone network, or payments made online for transactions whose terms were negotiated offline.
e-commerce is the online transaction of business, featuring linked computer systems of the vendor, host, and buyer. Electronic transactions involve the transfer of ownership or rights to use a good or service. Most people are familiar with business-to-consumer electronic business (B2C). Common illustrations include Amazon.com, llbean.com, CompUSA.com, travelocity.com, and hotels.com.
E-commerce can be divided into:

• E-tailing or "virtual storefronts" on Web sites with online catalogs, sometimes gathered into a "virtual mall"
• The gathering and use of demographic data through Web contacts
• Electronic Data Interchange (EDI), the business-to-business exchange of data
  e-mail and fax and their use as media for reaching prospects and established customers (for example, with newsletters)
• Business-to-business buying and selling (B2B)

DTM Dat Generator is a simple and easy tool to generate test data which is able to work equally well both with databases and with plain text files. In most cases the product enables you to create realistic test data without any special efforts. Let's dwell on some practical tasks of filling the database with test data.
If you are writing test case then you need input data for any kind of test. Tester may provide this input data at the time of executing the test cases or application may pick the required input data from the predefined data locations. The test data may be any kind of input to application, any kind of file that is loaded by the application or entries read from the database tables. It may be in any format like xml test data, system test data, SQL test data or stress test data.
Design your test data considering following categories:
Test data set examples:
1) No data: Run your test cases on blank or default data. See if proper error messages are generated.
2) Valid data set: Create it to check if application is functioning as per requirements and valid input data is properly saved in database or files.
3) Invalid data set: Prepare invalid data set to check application behavior for negative values, alphanumeric string inputs.
4) Illegal data format: Make one data set of illegal data format. System should not accept data in invalid or illegal format. Also check proper error messages are generated.
5) Boundary Condition data set: Data set containing out of range data. Identify application boundary cases and prepare data set that will cover lower as well as upper boundary conditions.
6) Data set for performance, load and stress testing: This data set should be large in volume.
This way creating separate data sets for each test condition will ensure complete test coverage.

Merchants should understand the difference between companies that provide data feed submission tools and full service firms which handle all aspects of data feed management. There are plenty of excellent tools that help merchants manage their own campaigns in-house but we are not one of them. Our goal is to provide our clients a comparison shopping management solution that frees them to focus on the day to day intricacies of running their own business.

CPC Strategy was founded in January 2007 by former employees of the comparison shopping engines. We saw firsthand how merchants were struggling to manage their spend and achieve their target ROI. It was frustrating seeing merchants making the same mistakes repeatedly again without even realizing what they were doing wrong. The lack of uniformity between CSEs makes managing multiple campaigns in-house very difficult and thus ineffective for most merchants.

We do all of the above as we are a true Full Service Data Feed Management Solution. We provide each merchant with an ftp for data feed updates and then we take care of the rest.
New feeds are generated based on the specifications of each CSE, and our system is set-up for daily deliveries and to track the results. A weekly report is also sent out to each merchant which breaks down ROI at the product level for each CSE Campaign.
In terms of specialty services, we pride ourselves on keeping up with the constantly evolving algorithms of each CSE via regular A/B testing. This helps us in understanding what each engine is looking for and enables us to manipulate our client’s data feeds accordingly.

If the engine accepts a data feed, we can work with them. A few examples include Pricegrabber, Shopzilla, Google Product Search, etc.

We have been working with CPC Strategy for almost one year. We switched to them after trying several other options including in house, other large, well known SEM Companies, and having some of the Comparison sites assist us directly. CPC Strategy has been the most effective of all! They are competent, professional, and work quickly.
