4Morphis is a tool that can automatically convert legacy Oracle Forms applications into modern web and mobile applications using ExtJS. It works by parsing the Oracle Forms XML files, constructing equivalent UI components in ExtJS, and generating code to link the UI events to backend database logic. The conversion moves the application to a three-tier architecture with the ExtJS UI, a Java persistence layer, and the existing Oracle database. 4Morphis handles the entire conversion process to output a developer-ready Sencha application that maintains the core functionality of the original Forms application.
SenchaCon 2016: Oracle Forms Modernisation - Owen Pagan
- 1. Oracle Forms Modernisation Owen Pagan Rapidly Converting Oracle Forms to Ext JS Apps
- 2. Session Agenda • What 4Morphis does? • How 4Morphis works? • Product Demonstration • How does your organisation run a conversion project?
- 3. 4Morphis: Automated Code (Re) Generation • We write code that writes code …using legacy Oracle Forms applications as source …regenerating it into web and mobile applications in Extjs 6
- 4. 4Morphis: Automated Code (Re) Generation • A tool to convert legacy technologies to mobile and web technology - HTML5, Javascript – (ExtJS, Sencha Touch) • It is drag and drop so converting hours not weeks • Converts front end and back end (business logic) • Moves application from two tier to three tier architecture • Allows legacy applications owners to get to mobile cloud/SAAS deployment
- 6. How does 4Morphis work?
- 7. What is the 4Morphis Forms Conversion Platform? A platform that empowers organisations to go from Oracle Forms to Sencha Ext JS 6 using an automated platform and SDK
- 8. How does 4Morphis work? • 4Morphis is drag and drop • There are 5 main stages in converting the form; 1. Upload FMB 2. Convert to XML 3. Parse XML to 4Morphis 1. CRUD’s, API’s 4. Creates UI & Logic 5. Deploys Zip for Download & View
- 9. What does the platform do? Consumes an Oracle XML output file and constructs a traditional 3-tier web application architecture with: • Sencha UI (Ext JS 6 Classic) • Java Persistence Layer (Stored Procedure over JDBC) • Oracle database (Generated API to hold existing customer PL/SQL) • Conversion reporting for use in customer post-generation development • Programmatic API access to customise generation process Full Source code is provided across the three tiers: • Database • Middle tier persistence and services • User interface The resultant architecture components are developer-ready for post-generation Feature-add and enhancements as required OracleForm Database API & CRUD Ext JS 6 Web App Conversion Reports Java Persistence Layer Full Source Code access
- 10. High Level Conversion Process • Deconstruct Forms XML and construct equivalent UI components Using 4Morphis UI Intelligence Technology • Generate and automate the linking of UI event processing with database stored procedure functionality • Generate a persistence layer communication framework between UI and Database with form API lookup ability Form Block Item Item Trigger Block Item Trigger Oracle Forms Basic Structure Sencha App Form View Grid Column Event Listener Form View Form Field Event Listener Generated Sencha UI Structure Templates Models Code Injection Conversion Process
- 11. High Level Conversion Process • Deconstruct Forms XML and construct equivalent UI components Using 4Morphis UI Intelligence Technology • Generate and automate the linking of UI event processing with database stored procedure functionality • Generate a persistence layer communication framework between UI and Database with form API lookup ability UI Generated Handler Functions Generated Sencha UI Structure PersistenceLookup Form 1 API Form 2 API Form 3 API
- 12. 2 Tier Oracle Forms Application Jar File Persistence Oracle Form Database Logic in Oracle Form Logic in Oracle database Data in database
- 13. 3 Tier Web Application Jar File Persistence EXTJS DatabaseLogic in Oracle Database PL/SQL Packages and Procedures Move some logic to mid tier e.g. show hide Front end capability to EXTJS - Grids, layout etc.
- 14. Maintainable Web Application Persistence Layer EXTJS Database Logic in Oracle Database PL/SQL Packages and Procedures Move some logic to mid tier e.g. show hide Front end capability to EXTJS - Grids, layout etc. Java Persistence Layer
- 15. Future Proofing Platform Jar File Persistence EXTJS DatabaseLogic in Oracle Database PL/SQL Packages and Procedures Move some logic to mid tier e.g. show hide Front end capability to EXTJS - Grids, layout etc. JAR Per Form JAR Per Form JAR Per Form JAR Per Form JAR Per Form JAR Per Form
- 16. Enhanced Performance Jar File Persistence EXTJS DatabaseLogic in Oracle Database PL/SQL Packages and Procedures Move some logic to mid tier e.g. show hide Front end capability to EXTJS - Grids, layout etc. JAR Per Form JAR Per Form JAR Per Form JAR Per Form JAR Per Form JAR Per Form • Maintainable code • Retire PL/SQL to Java • Future proofed platform
- 18. How does your organisation run a conversion project?
- 19. Partnership for Oracle Forms Modernization Oracle Forms Experts • Build and Maintain OF to Ext JS Converter Design / Develop / Test Tools and Services • Enterprise JS tools - Ext JS • Organizational & Product Support Services • Turnkey Application Modernization Services
- 20. 3 Pieces for Enterprise Application Modernization Asset Reuse The right people and process The right tools Professional Services
- 21. Starting a FCP - POC Phase 1: POC • We will run that code through our engine and be able to report on any gaps that there may be. • Requirement for Phase 1: • 3-5 representative FMB's - Under 3,000 lines of code! • Takes less than one day • We get a sense of the project
- 22. Starting a FCP - POC Phase 2: POC • Access to a cloud version of your database - AWS • On this you should deploy your database schema, with some data in it so we can validate the logic against sample data. • For this we will use the previous XML files exported from FMB's and also associated PLL files. • We link the 4Morphis engine to this and convert the Forms to EXTJS The set up of PLL's and linking takes us 3-4 days.
