5.1 | 1 | = REQUEA Applications = |
| 2 | |||
| 3 | Requea is a framework designed to build and adapt enterprise applications such as: | ||
| 4 | |||
| 5 | * ITIL - Incident, Problem and Change Management, ... | ||
| 6 | * Human Resources - Requests Management, Payroll, ... | ||
| 7 | * Facility Management - Room Reservation, ... | ||
| 8 | * Finance - Contract Management | ||
| 9 | |||
| 10 | Those applications typically require: | ||
| 11 | |||
| 12 | * A strong data management with complex relationships and ability to manage large data in a secured and transactional manner | ||
| 13 | * Flexibility to adapt to the specific and evolving business requirements of the customers | ||
| 14 | * Complete User access and security management | ||
| 15 | * Role base portal access | ||
| 16 | * A fast and intuitive user interface and user navigation | ||
| 17 | * Workflow capabilities for notifications, and approvals | ||
| |
6.1 | 18 | * Complete WebServices support for integration |
| |
7.1 | 19 | * Import / Export / Upload / Download of documents and file formats such as CSV, XML, Excel |
| |
5.1 | 20 | * Reporting capabilities |
| 21 | |||

4.1 | 22 | = The REQUEA Platform = |
| |
3.1 | 23 | |
| |
4.1 | 24 | The REQUEA Platform is a component that is typically installed in a standard web application server (J2EE such as Tomcat, JBoss, OracleAS, JonAs) and provides: |
| |
3.1 | 25 | |
| |
4.1 | 26 | * An OSGi architecture within the web application for modularity and extensibility of the platform |
| 27 | * An document based model architecture (MDA) for creating document based application where the data manipulated is easily and effitiently stored in a database (such as Oracle, MySQL, Microsoft SQL Server). | ||
| 28 | * A web user interface that is optimized for speed, ergonomics and complex interactivity with the user. | ||
| |
3.1 | 29 | |
| |
4.1 | 30 | = Platform services = |
| |
3.1 | 31 | |
| |
4.1 | 32 | The platform runs on top of standard J2EE application server and uses J2EE services provided by the environment (such as Servlets, JDBC, ...). |
| |
3.1 | 33 | |
| |
4.1 | 34 | The platform provides the following services: |
| 35 | |||
| 36 | * database storage persistence service | ||
| 37 | * application business rules | ||
| 38 | * user interface service | ||
| 39 | * import / export services | ||
| 40 | * WebServices interfaces (SOAP) | ||
| 41 | * Java Content Repository interface | ||
| 42 | * Workflow services | ||
| 43 | * Reporting services (JasperReports integration) | ||
| 44 | * Graphs and Statistics services | ||
| 45 | |||
| 46 | All those base services are provided as OSGi services (packaged in bundles) | ||
| 47 | |||
| 48 | On top of those base services, we find the applications that are also OSGi bundles: | ||
| 49 | |||
| 50 | * Core applications, such as security and user definitions | ||
| 51 | * Standard applications, such as calendar, events, resources and catalog management | ||
| 52 | * Applications such as ITIL incident management | ||
| 53 | * Customer Specific applications where customer specific code may be created | ||
| 54 | * Customer customization where changes in labels, workflows, ... for a specific implementation can be added. | ||

4.1 | 60 | |
| 61 | = Applications and Bundles = | ||
| 62 | |||
| 63 | Applications are packaged in OSGi bundles (see bundles: [[Bundles>>Bundles]]) that can be deployed on a modular fashion. This provides flexibility and modularity to the platform. |
