Rapid product and process realization are major elements of competitiveness for the manufacturing industry, so efforts must focused on early stage of product development, where the product lifecycle cost is decided at that stage. Computer Integrated Manufacturing (CIM) has largely answer as technology demonstrators for large corporations, which their industrial implementation was suffered by their high cost and complexity and lack of infrastructure support. Recently a new system with a name of Concurrent Engineering (CE) system helps which product development and manufacturing processes growth in the same time. Digital enterprise technology (DET) can explain digital modeling of products development. The physical to digital environment encounters large scale of technologies that is useful for bidirectional transfer and mixing of data, models and expert feedback between digital and physical domain which these technologies are: 1- evaluating simulated performance can plan and analyze the manufacture systems. 2- Measurement technologies and digitization technologies, which means
Measurement technologies for the identification of location and orientation of processing elements and the Measurement technologies for the identification of key products feature.
In addition, use of data structure for manufacture products is shown in digital manufacture, Product data management (PDM) and commercial system for product modeling.

Nowdays the advantages of using internet in our dailylife is clear to everyone, the internet engage most of the people specially educated people to use it for their activities such as virtual enterprises, supply cahins and e-commerce. Michael Rappa (2007) claims digital markets help buyers and sellers to use internet servises such as exchanging or buying some insruments through the internet as one of the important managing digital enterprises and unlike the tradotional markets, the transaction between customer and seller donot need any in-person implication. Digital markets are open all around the clock, customers have opportunity to find the information of a product in different digital markets through the internet.

Inaddition, there are two different ways for e-business such as Business To Consumers (B2C) like e-tailing and Consumer To Consumer (C2C) such as e-bay, in these e-business, so customers are playing an important role in digital marketing, and communication help customers to find powerfull sites forexample, E-mail, web-base, SMS create realatinship between costomers and sellers. Moreover, many systems such as ERP( Enterprise Resource Planning) system and SCM (Supply Chain Management) system pushed traditional markets into digital markets, so, collabration between traditional and digital markets have been increased sharply. It is not beyond the scope, internet makes marketing in digital marketing more competetive, so sellers should expand use of computers, data, technology, information and internet.

The advance of internet technology in digital markets helps to most of organisms and consumers to use the benefits of electronic Information Technology (IT) in electronic markets (e-market) with the name of electronic commerce (e-commerce). Some technologies such as Electronic Data Interchange (EDI) and Electronic Funs Transfer (EFT) are using for transfering daily business documents in digital markets like purchase orders. Moreover, in Business Intelligence (BI) raw information about products are saving in company's database which all of data may about customers information, documents promotions of the company and payment methodes.


Inaddition, there are two different ways for e-business such as Business To Consumers (B2C) like e-tailing and Consumer To Consumer (C2C) such as e-bay, in these e-business, so customers are playing an important role in digital marketing, and communication help customers to find powerfull sites forexample, E-mail, web-base, SMS create realatinship between costomers and sellers. Moreover, many systems such as ERP( Enterprise Resource Planning) system and SCM (Supply Chain Management) system pushed traditional markets into digital markets, so, collabration between traditional and digital markets have been increased sharply. It is not beyond the scope to mention internet makes marketing in digital marketing more competetive, so sellers should expand the use of computers, data, technology, information and internet in their e-markets for their own benefits.

ofcourese the advantages of e-business can overcome to its disadvantages and now most of the
educated people prefer to as it as a beneficial thing.
