About Web2.0-from IBM

Web 2.0 has eight core models:

Collective Intelligence)

Build a participating architecture with the help of network effects andAlgorithmSo that the software is getting better and better as more and more people use it.

Data, next "Intel Inside"

Using unique and hard-to-replicate data sources has become the "Intel Inside" of this era. data becomes as important as functions and becomes the core competitiveness.

"Compound" Innovation

Build a platform to create new markets and opportunities through a combination of data and services.

Enrich User Experience

Beyond the traditional web page mode, online applications have the same rich user experience as desktop applications.

Supports multiple devices

Supports various devices connected to the Internet to provide users with ubiquitous and seamless online experience.

Software as a service (SAAS), and perpetual Beta)

It has changed the traditional software development and use model and switched to the permanent online, continuous update, and software-as-a-service model.

Use long tail

Leverage the capabilities of the Internet to reach very large customers and low-cost marketing methods to make profits in the "niche" market segment.

Scalability of lightweight models and low-cost advantages

Uses lightweight business models and software development models to quickly and cheaply construct products and services.

Impact of Web 2.0 on software:

The Programming Model of Web 2.0 is being formed, which includes the following important parts.

1. A lightweight programming modelIs to use rest and feed, and sometimes consider soap. For example, Amazon provides both rest and soap,CommunityThe proportion of rest is higher.

2. Data ServiceData Service combines, filters, converts, and eliminates data inconsistency from different sources, and provides necessary quality assurance, such as data consistency, security, access control, and data management.

3. Provides Internet and Web applications with rich user experienceIn combination with Ajax, HTML, XHTML, CSS, Dom, XML, and XSLT, XMLHttpRequest and JavaScript are used to bind everything together, so that online applications provide a rich user experience just like desktops.

4. Mash-able assetsTo convert content and IT assets into assets that can be flexibly restructured, and use the lightweight content aggregation method of the Internet to build a composite Web application.

5. Enterprise mashup PlatformSo that those who need content and information can easily aggregate and reorganize content and data from different places to quickly meet their changing needs due to the situation.
