Introduction to Entando Architectural Model

Hi guys,

today I present to you the last post published on the blog Entando:

Entando architectural model is composed by three layers:

• Data Access Layer: It is composed by all the elements which superintend the Persistence Layer. The main component are the DAO classes (Data Access Object) which are the only linking element between the framework and the data sources (Database, Filesystem, LDAP service directory etc.)

• Business Layer: This is the core of the system. Here the concept of Entando service as manager of every macro functionality, takes place. This layer is built upon the Spring Framework, whose listener, during the system start-up, initializes all the services and injects them in the web application context as beans. The Business Layer utilizes the Data Access layer to get the data needed, gives to the higher layer (the Presentation layer) the elements to display and supports it in the execution of actions.

• Presentation Layer: the aim of this layer is to build the graphic interfaces which represent the mean through which the users interact with the system. This layer gives a pure View layer (that is, a JSP without any business logic) and a "slim" controller (which checks the consistency of the data submitted and serves the data produced); both of them provide support to the layer below, the Business Layer. In the Entando framework this layer is divided in two parts:

             - the Portal View, referred to as Front-end
             - the Administration View referred to as Back-end

SOA and Enterprise Inter-Operability with a Portal

Last Post from Sam’s World

Enterprise based portals employ a desirable set of functional characteristics that provide value any number of ways. While ROI and other business calculators are engaged to offer a compelling business argument to the introduction of a company based knowledge repository, my focus will instead lie with efficiencies derived from penetrating the middleware platform of an enterprise. Several benefits provided through the use of web-based portal services & SOA are what I will explore in this post. There is a dominant, myopic perspective in which enterprise portals are viewed as an information architecture and not for what they are – an application. The architecture establishes the foundation for a common view of the data, applications, and a common management interface for content. However, the real benefit of an enterprise portal comes from the convergence, not from the web based display mechanism. This fusion differentiates enterprise portals from a collection of web sites by offering

1. universal access to information,
2. role-based personalization,
3. cross-application workflow,
4. common content management, and
5. centralized user management.

Entando Meets Open Data

Last post from Entando Universe :

“Open Data” has become the trend of the moment. Social networks, blogs, magazines on the web speak about about Open Data.
But first of all we need to define what is open data:
“Open Data is data that can be freely used, reused and redistributed by anyone - subject only, at most, to the requirement to attribute and sharealike.” as defined by the Open Definition.
The full Open Definition gives precise details as to what this means:

• Availability and Access: the data must be available as a whole and at no more than a reasonable reproduction cost, preferably by downloading over the internet.

• Reuse and Redistribution: the data must be provided under terms that permit reuse and redistribution including the intermixing with other datasets.

• Universal Participation: everyone must be able to use, reuse and redistribute - there should be no discrimination against fields of endeavour or against persons or groups.

Governments have a broad range of different types of data and most of the government data is public by law, and therefore could be made open and made available for others to use. For this reason Open Data is often associated with Open Government.

Enterprise Portals Deliver Unmistakable Value for Today’s Business Needs

New Post from Sam’s World

Organizations that employ and support a distributed workforce increasingly face a dilemma. The absence of critical information often has a negative impact on employees whose livelihoods remain dependent on the access to data housed in company repositories. To address this issue, businesses are increasingly turning to portals to fill this void.
