The Web 2.0 world has evolved, and has evolved considerably. It’s no longer about getting data from the universe of information -- but collaborating, publishing, sharing and deriving business intelligence from the data. The landscape of information now consists of smaller fragments of relevant data commonly known as mashups.
So when a bank searches its database for a customer, it no longer expects to get the name of the customer. But instead expects to get back a data grid of all the accounts linked to the customer, a pie chart showing all the different asset holdings (equities, loans etc), a Google map showing the address of the customer and any relevant alerts on the customer account. And that’s not it -- all the information should be seen on a single unified page! Think it’s difficult? With IBM® Mashup Center, you can access the components that you need to create Web 2.0 mashup and application solutions.
What is a Mashup?
Mashups are situational applications which aggregate disparate data. Mashups add a lot of value by associating data elements that are relevant for the users.
With Mashup Center, you can
- Create situational apps which are reusable assets
- Facilitate rapid development of dynamic web applications (widgets)
- Create feeds from numerable data sources
- Empower business users to create and share mashup applications, widgets, feeds, and services
- Provide business intelligence by associating the data elements.
The Architecture
Key Components
Catalog: The catalog is a repository. All feed, feed mashup, and widget information is kept in the catalog.
Widget: A widget is a miniature application that is embedded within an HTML page. With a widget, dynamic content is displayed on the page.
Feed: A feed contains XML data. RSS, Atom and XML feeds are available on the Internet. An example of an RSS feed is the top news stories from Yahoo!, available at http://rss.news.yahoo.com/rss/topstories. Feeds in MashupHub can be created using different data sources and then accessed via a URL.
Page: A page is a collection of widgets and other HTML markup that can be displayed in a Web browser. A page can be a mashup application or a regular Web page.
Why should your business use Mashup Center?
Mashup Center is a great tool for rapid assembly of dynamic web applications. The Mashup pages provide a lightweight web solution that combine application and information to solve many different business needs. Around the inter-web there is a fair amount of interest in mashups and many perceive it as better medium.
Mashups provide a user interface to data from variable sources (or feeds) like Web services, enterprise databases, spreadsheets, even BI warehouses like Cognos. Portability is a valuable add-on provided by Mashup Center. Development and product teams can build mashup pages/widgets and easily expose it to any intranet, internet or enterprise portals (even to Microsoft Share point).
With IBM Mashup Center business stakeholders get the freedom to assemble applications that cater to their requirements. Business users can combine, transform and reuse the mashups to create visualizations and provide real-time collaboration.
Mashup wiring enables you to collaborate data for a more unique, dynamic interface. So let’s say for example, a map widget can be wired to several feeds like real estate listing, company address, customer listing, hotels and restaurants. You can also wire the customer listing to its stock prices, relevant market news for the customer etc. You get the idea. Wiring widgets is extremely intuitive and easy to use.
Mashups and WebSphere Portal
Mashups are usually meant for creating applications which are developed in a very short time to target a very specific business problem. It is generally recommended to develop mashups when flexibility and time-to-develop applications is more important than governance and traditional development model provided by WebSphere Portal.
Pre built widgets (like graphs, reports, Google Gadgets) make Mashups more suitable for visualization and aggregation of data from different data sources on a single screen. However for a more transactional based enterprise system, WebSphere Portal is much better suited.
Style of development for portlets and mashups is also different. Widgets can be developed using different tools and have a relatively small and a generic code base. Feeds can be developed visually or by writing native SQL. Developing portlets require a more structured model by incorporating one or more design patterns and/or frameworks (Struts, JSF etc).
WebSphere Portal provides a much broader set of features like Virtual Portal, SSO, Content Management, Collaboration, advanced security model on Pages, Portlets and resources, Portal search, impersonation. These set of features are key differentiators between the WebSphere Portal and Mashup Center.
Mashup applications can run along side or within the portal framework, it all depends on the solution designed. WebSphere Portal 6.1.5 provides the ability to render Mashup Pages and widgets within the portal container. At the same time, Mashup Center can render any Portal page by providing the appropriate URL for that page.
