Ebase Architecture
Ebase
Processor
Ebase Designer
Ebase is written in Java and can run under any J2EE application server. The following diagram describes the system architecture.
Ebase has these major components:
- Processor
- Designer
- Presentation Manager
- Adapter Manager
- Repository
Ebase
Processor
The processor is the Ebase processing engine and comprises a
- Processing Kernel
- Presentation Manager
- Adapter Manager
It’s purpose is to:
- co-ordinate with the adapter manager to read and write data from external data resources
- co-ordinate with the presentation manager to present a form formatted to the correct output device i.e. web browser, PDA etc. and rendered in the required country language
- execute form defined validation scripts against entered data
- manage form concurrency, transaction and locking requirements
- manage the Ebase cache to achieve optimal form performance and throughput
- perform error management and logging
The Ebase processor is a Java SERVLET application and runs under any J2EE compliant application server.
Ebase Designer
The Ebase Designer is a comprehensive Java based GUI that enables forms to be developed and deployed.
Ebase Designer functionality includes:
- definition of form components such as pages, fields, tables and field groups
- configuration of external data resources e.g. databases, messaging systems etc.
- mapping of form fields to external data resources
· customization of form presentation templates
· multi-lingual text definitions
- development of form processing scripts using the Ebase form processing language (FPL)
- support for multiple concurrent designers
- designer security model
The Ebase Designer GUI is designed to simplify the form development process with strong focus on convenience features such as:
- drag and drop
- direct form field import from databases
- data resource connectivity tests
- transparent mapping of form entered data to and from defined data resources
Forms may be stored in projects within Ebase Designer. Form security and user access control is managed via the Ebase security module.
The Ebase Designer is 100% Java based and executes as a standalone Java application.
Ebase
Repository
The Ebase repository is a server-side data store holding all defined forms. The repository may be any JDBC compliant database.
Forms are developed via the Ebase Designer. The forms accesses the Ebase repository via the Ebase Designer server side service. All access to the Ebase repository is via the Ebase Designer.
At run-time the processor retrieves form definitions from the Ebase repository.
