IFML Quick Reference Card is the new one page document to print and keep on you desk when you want to learn the new OMG standard IFML (Interaction Flow Modeling Language), the modeling language for the User Interaction definition.
In a Web application, feedback messages are used to notify the user about the result of a business logic execution.
Feedback messages vary depending on message types, which can be: success, information, warning, or error.
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.
In t...

A rich text editor can be useful when you want the user to be able to write...
An important aspect of a Web application is its Visual Identity.
The Visual Identity represents all the graphic widgets that you may want to use in order to make the Web application look good while providing a great user experience.
WebRatio lets you create Web applications with a great Visual I...
Validation is used to check that the data inserted by the user via the application’s user interface complies with the requirements of the application domain.
Validating the data, for example data that is inserted into a form (or in any other View Component or View Component Part with input capabili...
This lesson gives you the basic knowledge required to define reusable portions of IFML models using the module and module definition concepts.
Working on real-world Web applications may require modeling a large project. In this situation it’s important to be able to manage the project to avoid loss...
This lesson gives you the basic knowledge required to define common content in an IFML Model through the "Master Page" concept.
Working on real-world Web applications may require modeling a large project. In this situation it’s important to be able to manage the project to avoid loss of control and...
Learn how to enrich the Domain Model with calculated information, derived from the materialized data existing in the Domain Model itself. This process is called "derivation", since it creates redundant information that can become handy when defining IFML models. Derivation can be applied by using va...
Learn how to speed up your productivity by letting WebRatio Platform create physical elements on the database starting from your Domain Model, or letting it extract the Domain Model starting from an existing database structure.
Forget about writing SQL by hand! WebRatio Platform helps you generate ...
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 ...
In the lesson dedicated to the Domain Model Overview, you learned about the Entity-Relationship model and its main concepts: Entity, Attribute and Relationship.
The representation of the Domain Model in WebRatio Platform is quite similar to the Entity-Relationship notation ad it is based on the sam...
In a Web Application, we often need to grant different groups of users access to different resources. For example, in a Web Application used for Enterprise Resource Planning, the head of Human Resources will have access to all the employees’ sensitive data (such as person details, salary, etc.), whi...
The Internet is a telecommunication infrastructure that enables many of today’s most prominent technologies and applications. Familiarizing with the main notions, keywords, and acronyms used in this context is important in order to better understand the role of WebRatio Platform and the structure of...
The goal of this portal is to explore and discuss when, where and how software modeling and model-driven engineering (and when NOT) can improve current software development practices.
“Single sign-on (SSO) is a property of access control of multiple related, but independent, software systems. With this property a user logs in once and gains access to all systems without being prompted to log in again at each of them.” (source Wikipedia).
WebRatio allows you to enable the single ...
To get the Web Application from your Web Project, you have to generate it. When a project is generated, the Application Server loads the corresponding Web Application. WebRatio uses Apache Tomcat as the default Application Server Apache.
Tomcat implements the JavaServer Pages (JSP) and Sun Microsys...
Downloading, registering, and activating WebRatio Platform involves several decisions that are not easy to take without proper knowledge. Attend this lesson to understand all the steps and to find some help if something goes wrong.
Domain-Specific Modeling (DSM) is the latest approach to software development, promising to greatly increase the speed and ease of software creation. Early adopters of DSM have been enjoying productivity increases of 500–1000% in production for over a decade. This book introduces DSM and offers exam...
When carefully selected and used, Domain-Specific Languages (DSLs) may simplify complex code, promote effective communication with customers, improve productivity, and unclog development bottlenecks. In Domain-Specific Languages , noted software development expert Martin Fowler first provides the in...
Learn how to migrate your WebRatio 4.3 project to WebRatio 5.0.
This document contains all the instructions needed for the migration process.
Subversion is a free, open-source revision control system (RCS). Subversion manages files and directories over time. These files and directories are placed into a central storage called a repository. The repository is quite similar to an ordinary file server, except that it remembers every chang...
Developing the front-end of a user application is a costly and inefficient process for a number of reasons.
WebRatio Platform has solved the User Interface modeling challenge by developing an interaction Flow Modeling Language, or IFML, which covers the existing gap in front-end application develop...
When you get to a new town it is likely that you want to look at a map of the town. In the same manner we start with providing an overview of the main parts of WebRatio Platform. WebRatio Platform is built on Eclipse. Even though you could be familiar with Eclipse it is worth watching this brief tut...
The web model is where you use the IFML Web Extensions to build the user interface of your Web application, and where you specify the business logic for each IFML action using a set of predefined operations.
In this lesson we introduce the View Containers you can use to organize your Web applicatio...
This is the first lesson that explains the Domain Model in WebRatio Platform.
In this lesson, we introduce the main concepts related to the Domain Model, including a deep analysis of the notation adopted - Entity Relationship (E-R). The following lessons show some detailed content and will explain ...
The purpose of this technical document is to provide instruction on installing, configuring and using the WebRatio License Server. The WebRatio License Server manages the distribution of WebRatio licenses in use and checks the limit on the maximum number of concurrent users. A user can work only if...
WebRatio 7.2 introduces the first steps for IFML compliance. IFML is the new OMG standard language for modeling the application front-end.
