In a Web application, you often need to manage the information shown to the user.
Managing information means to create, update, or delete information.
In this lesson we discuss an enhanced version of the Data Management pattern, which allows you to manage more than one piece of information at th...
When you are working on a new Web application, you will need to implement a set of common features. In the previous lessons you learned how to model these features in IFML, concentrating on the user interaction.
These features cover how to publish and maintain information, as well as the login ...
When you are working on a Web application you have to consider both the user interaction and the application behavior executed when the user triggers an action. The application behavior can be any kind of business logic you may need to express.
WebRatio Platform provides you with a set of componen...
In a Web application, you often need to manage information that is shown to the user. Managing the information means to create, update, or delete information. With WebRatio Platform you can easily model an administration section so that the Web Application user can manage the application data.

When you are working on a new Web application there is a set of common requirements that you are going to implement many times. In IFML lessons you learned how to model several commonly recurring requirements focused on the user interaction.
Recurring requirements comprehend how to publish and ma...
Usually, Web applications are not standalone; they need to integrate with external systems and other applications in the company intranet. The best way to make different Applications communicate with one another is to use a Web service infrastructure.

Data management is the crucial aspect for Data Centric Web applications. So far you learnt how to create, read, update and delete data, but data is meant to be shown in so many different ways.
Reading data through View Component is not the only option you have in WebRatio Platform.
Imagine that y...
The Connect Operation is an operation used to enable the association between instances of two entities (the source entity and the target entity), connected by a specific relationship role.
This article guides you to the usage of the Connect showing also a working example.
The Disconnect Operation is an operation used to delete the association between instances of two entities (the source entity and the target entity), connected by a predefined relationship role.
This article guides you to the usage of the Disconnect showing also a working example.
The Query Component is available starting from the WebRatio 5.1 version. It's a Utility Component that permits to execute a custom edited query using the HQL(Hibernate Query Language) or SQL query language. Moreover it can dynamically compose an HQL query depending on the incoming Domain Model ident...
The Stored Procedure is an Operation that allows calling a procedure stored in a database.
To use this Component correctly, the procedure must be previously created in your database.
Discover how to use the Stored Procedure reading this article.
The Parameter Collector Operation permits one to collect a set of parameters from multiple sources and to redistribute them to multiple targets. In this way, the operation reduces the model complexity by deleting some data flows, improving its reading and creating a neater model.
The Jump Operation permits to jump forward and backward within the application without modeling an explicit navigation flow. A forward jump redirects the user to the specified Parameter Collector Operation. A backward jump redirects the user to the last visited Jump Operation and follows that operat...
The Math is an Utility Component designed to parse and evaluate mathematical expressions. A mathematical expression is composed by variables and operators and can be either statically defined at modeling time or dynamically provided through an input parameter at run-time. The Math replaces the varia...
A job is a sequence of operations that has to be executed asynchronously by the application. It's possible to schedule a job at a specific time or interval, which means that jobs can be automatically triggered (scheduled when the application starts). It's also possible to schedule a job at runtime: ...
In a Web application you may need to specify a piece of business logic that is executed periodically.
In this case, the execution is not triggered directly by a user interaction on the Web application, but is triggered automatically at a specific timestamp. WebRatio Platform lets you model this ...
The Domain Model Utility Component is available starting from the WebRatio 5.1 version.
It's a hybrid unit, which means that it can be placed in every View (Site View, Module Definitions View, Service View).
It permits to retrieve information about entities and relationship of the Domain Model....
The UnsupportedClassVersionError can occurr in a Web Project that uses custom components, such as custom validation rules, servlets or listeners.
All these components are developed using a different project (e.g. a Java project) in which you have to compile the Java classes and create a jar file...
In WebRatio it's possible to generate PDF, Excel or RTF reports. This article discusses a particular usage of the WebRatio generated reports.
