E-COMMERCE!!

B2C Business to customer: Offer things to the final consumer, is the typical internet store!! select the products adding them to a cart and are paid with credit card!

Example: www.abercrombie.com is the official site of the brand, there you find the possibility of viewing new collections, and also change all the colors and mix them in a very interactive way, this allow customers to find an specific product size it and buy it, is like having the store in your computer screen. they give you a shopping bag!!!

B2B Business to Business: Alibaba is the greater example of a B2B, is a portal in which you can buy not only raw materials from china, but others specialized china products. B2B facilitates access to every entrerprise with out going to the place!!!

Example: www.alibaba.com it is great surfing though that web they place the entreprise you are looking for and the sector you are looking for, many of that companies started with out paying and give them a trust pass this is like a certificate given to the companies which permits to locate them and have reliable information of them.

G2C: is kind of e-business example in which citizens use internet to connect with government!

Example: www.dian.com.co is the duties and tax entity which allow citizens to pay their taxes.

C2C: Ebay is a place in which you as a consumer can reach other consumers!

Example: www.metrocuadrado.com is a real state portal in which consumers contact with other consumers to sell their houses or apartments.

P2P: Peer to Peer; allow users to share folders in between with out any intermediaries. NAPSTER, EMULE & ARES!

Example: Bitcomet is a torrent which uses a interchange protocol designes to interchange, the great thing of bitTorrent is that when many people is downloading some speceific folder insted of slowering it make it quicker, each node contributes to the distribution of the folder

whaT are html & xml??

HTML III

W3C is an institution which collect all the internet protocol standards, it is managed by Tim Berners-LEE

XML

Extensible Markup Language (XML) is a simple, very flexible text format derived from SGML (ISO 8879). Originally designed to meet the challenges of large-scale electronic publishing, XML is also playing an increasingly important role in the exchange of a wide variety of data on the Web and elsewhere.

The Main Difference Between XML and HTML
XML was designed to carry data.

XML is not a replacement for HTML.XML and HTML were designed with different goals:
XML was designed to describe data and to focus on what data is.HTML was designed to display data and to focus on how data looks.
HTML is about displaying information, while XML is about describing information.

XML was not designed to DO anything.

XML was created to structure, store and to send information.

XML is not a replacement for HTML.
In future Web development it is most likely that XML will be used to describe the data, while HTML will be used to format and display the same data.

XML is a cross-platform, software and hardware independent tool for transmitting information.

XML will be as important to the future of the Web as HTML has been to the foundation of the Web and that XML will be the most common tool for all data manipulation and data transmission.

INTERNET FIRST STEPS!!

Lick was a guy who desinged networks, he gave great contribution to the actual network!!
Lick was asked to join ARPA (advanced research project agency).
1966 lawrence create ARPANET I conmutation packages.
1969 ARPANET II 22 computers conected.
1980 tcp/ip standard internet protocol.
1983 due to the growt of ARPANET users separetes into MILNET, also it appeared two new applications: TELNET allows to conect between pc's and use their programs, FTP is a technology that allows to upload and download information!!!
1989 Tim Berners-Lee created the HTML (Hyper text Markup language) way to unify information on the web.
1990 the core of internet was of 21 nodes and 46 mbps., about 50000 net conected arround the world.
1993 first grafic navigator MOSAIC
1994 First comercial use NETSCAPE

URL (uniform resource locator) names are translated into IP Address, which are numbers of 32 bits, separed into 4 parts, start from 232 address, 4000 millions!!

DMS domain main servers!!

INTERNET 2.0!!!! find more than 4000 million of addresses it's separed into 6 parts!!

HTTP (Hyper Text Transform Protocol) give the way of comunicating with the server if there is a protocol secure must stand an "s" at the end.

SMTP
POP using mail protocols!!! connect to e mails bringing the information from the mail box, to your outlook which is an aplication stored in your pc!!
IMAP II
SSL (SECURE SOCKET LAYER) way to encript information, it is fundamental to garantiee the e-commerce and secure payments through the web!!

PING allows you now if the server is busy!!

UKAKEA & Zylab Case Studies!!!

UKAKEA UK Atomic Energy Authority!!!
the main task is to mantain the documents which are of public interest!!!


Every single piece of information must be available in the future because people pass throught but organizations maintain!

The nuclear sector and its new regulations are encouraging the demand of complete information systems!
As a public organization with base in the european union, must present a public offer!!!

Pilot program showing the benefits was made in the human resources department which used greatest amount of information. the pilot progam show success!!!

Zylab create a system of electronic storage which remains in three aspects!!!

• sistem must be able to store & retrieve at great speed documets in every language


• every memeber of legal team must be able to find document on line from every place of the world and have complete accesibility to them.


• every kind of project, like mergers and adquisitions, need a simple sistem for the creation, access and storage in a extense group of archives..

TRENDS IN ELECTRONIC DOCUMENT STRUCTURES

Away from the management of static documents toward complex, compound documents.
Complex, compound documents at the far end of the continuum, however, exhibit none of the above characteristics. They are not tied to one application or platform; they are dynamic, constantly in a process of change; and they are "intelligent", carrying information about their content and structure.

Object-oriented architectures, where information is contained in objects— units of information of a finer granularity than traditional documents in this new object-oriented conceptualization are considered to be containers of a wide variety of information, rather than single flat files or blobs. Instead, they are simply a collection of pointers to external elements that are dynamically assembled as they are retrieved.


The resulting compound documents can be delivered as one of two types:
1) pre-specified documents that are constructed in the same way each time;

2) virtual documents that are assembled for a specific purpose, that exist temporarily, and which may change from one viewing to another.

DMS??? WHAT???

Well, DMS are document manage systems!!!!

the explanation--------->>

80% of corporate information resides in documents!!!!
Document management is the automated control of electronic documents from initial creation to final archiving.

Greater control over the production, storage, and distribution of documents, yielding greater efficiencies in the ability to reuse information, to control a document through a workflow process, and to reduce product cycle times.

2 classes of document management:
1) management of fixed images of pages.
2) management of editable documents, such as word processing files
and spreadsheets.

These two classes differ largely in the fact that images are static, while editable documents are dynamic and changing.

It is important to note that document management is not yet a single technology, but several.

The major challenge at this time is the integration of several software packages alliances and creating common standards to provide an open approach to the technologies.

ELEMENTS OF (DMS)

Underlying infrastructure: Interconnected by LANs and/or WANs. It must have characteristics such as network operating system independence, file format independence, location independence, long file names, and link tracking.

Authoring: support document creation.

Workflow: coordination of tasks, data, and people to make a business process more efficient, effective, and adaptable to change. The path of a particular document is determined by the document type. It supports functions such as authoring, revising, routing, commentary, approval, conditional branching, and the establishment of deadlines and milestones.

Storage: The core of the DMS is the database and search engines supporting storage and retrieval of documents DMSs are moving toward object-oriented databases.

Library services: refer to document control mechanisms such as checkin, checkout, audit trail, protection/security, and version control.

Presentation/distribution services: Presentation and distribution concerns the form and manner in which users are provided with information. DMSs should allow "multipurposing" where information can be distributed in different formats, such as viewed on a network
