Modern Innovative Solutions…

With the people who know the business

slide7

The power of the LanguageSimple and familiar…. yet robust and complete

  • Rich data types
    • Primitive
      • Simple (int, string, boolean, etc.)
      • Complex (any, arrays, dynamic arrays, dictionaries, array dictionaries, etc.)
    • User defined Data Parts
  • Keywords
    • Case, if-then-else, while, for loop, for loop cycling through a database result set, etc.
  • High power language capabilities
    • Automated Casting (e.g. using AS operator)
    • Mixing data types in assignments and expressions
    • Exception handling
  • Rich libraries of built-in functions
    • Math, string, date/time, system, i5/OS objects APIs
  • Robust integration with existing investment or access to low level APIs
    • Call RPG, COBOL, C, etc.
    • Full Java interoperability
      • Invoke Java from EGL (map Java classes with EGL External Types)
      • Invoke EGL from Java
the power of abstractions and declarative programming
The power of Abstractions and Declarative programming
  • Data access:
    • “Records” provide access to:
      • SQL, Indexed, Relative, Serial, DL/I, Service data, Message Queues
    • Common Verbs for data access (Get, Add, Replace, Delete).
    • Allows complete access to SQL statement if needed.
    • Common Error Handling.
  • Remote Invocation
    • Call COBOL, RPG, C, Java.
    • Linkage information separated from code.
    • Data mapping, protocol invocation all resolved at runtime, NO code necessary
  • User Interface:
    • EGL “handlers” hide complexities of
      • Web (JSF) UI
      • Reports (BIRT)
      • Portlets
      • Rich Web (Ajax)
  • Validation/Editing Rules:
    • Via properties in “Data Items.
    • Define formatting & validation rules in a common place.
    • Reuse data items for Records, screens, web pages, reports.
the power of tools
The power of tools
  • Web development
    • Integrate seamlessly with Page Designer and JSF tools
    • EGL native coding within JSF, mask all JSF complexity
    • Drag drop, code behind
  • Powerful IDE
    • Smart EGL editor, Code templates and snippets, Code completion
    • SQL visualization, editing, validation
    • References and declarations, Refactoring
  • Integrated interactive Debugger
    • State-of-the-art
    • No compile necessary, just click and aniimate execution as you define the code!
    • Full control, step, run, reposition, skip, change variables content, etc
  • Model Driven Development tools
    • Generate fully functional CRUD applications from UML models or Database schemas
      • including default JSF, and EGL or Web Services!
the power of services built into the language
The power of ServicesBuilt into the language
  • Service part:
    • a generatable part containing code that will be accessed:
      • from EGL code by way of a local or TCP/IP connection (EGL Service).
      • from any code by way of an HTTP connection (EGL Web service).
  • Interface part:
    • Used to access external services as EGL services or simply to provide separation of concern.
  • At development time…
  • Focus on the business logic
  • Implement SOA design elements: services and interfaces
  • Leverage existing business developers for new SOA development
  • Ignore deployment targets/technology while coding/testing
  • Leverage external web services…
  • EGL Interfaces
    • represent external web services
    • are created via import from WSDL
    • allow the EGL developer to stay within the context of EGL programming
  • Deploy EGL services…
  • To any platform (Java to WAS/Tomcat, COBOL to CICS, i5/OS )
  • As a Web service (uses SOAP)
  • As a private service (uses CICS ECI or TCP)

EGL Rich UI

Web 2.0 made easy

  • Why Rich Internet Applications (RIA)?
    • Applications are responsive and user friendly (user productivity)
    • Applications can leverage services “mush-up (business innovation)
  • Why is it hard to create RIA
    • Need to know many low level intricate technologies
    • Compound the slill/tool silos and fragmentation
    • Currently domain of “tech heads”
  • EGL and Rich UI
    • Includes visual composition, libraries of RUI widgets
    • Instant deploy/visualize while you code
    • Fully open and extensible
    • Easily integrate/consume any service (REST or SOAP)
    • Single language end-to-end
    • Brings legacy data and assets to Web 2.0

** Branham Study April 2008

arkansas data services deliver b2c retailer web solution
Challenge:Deliver a Web based B2B ordering system for wholesale men’s formalwear rental business with little to no web development experience

Solution:Leverage existing Order entry system (RPG) core functionality with a completely new JSF based interface

Results:In the time allocated for a prototype, ADS had the entire system up and running ready for final test

“Our original estimate for this project using Java/JSF was 4-6 months and our client would never accept that. With EGL we were ready for test in 4 weeks!”

Rusty Gadberry - Arkansas Data Services

kbc unify application dev across platforms and transaction managers
KBCUnify application dev across platforms and transaction managers

Challenge:

  • High costs and low responsiveness to business: redundancy and duplication across IT groups, fragmentation of languages and tools

Solution:

  • Leverage EGL to achieve the Cross-System components development, eliminate skills silos among their dispersed development teams, eliminate various platform specific languages and tools

Results:

  • Enable component based architecture. Shift to component based architecture, product factories and multi channel.
  • Created interchangeable developers. Shift from monolithic (3270) applications to browser based and open systems. Transform 600 mainframe developers to multi platform developers (Unix, mainframe, WAS, IMS).

“… We want to avoid the ‘skill silos,’ what we really need is a large group of general developers who should not worry about target platforms and focus on developing business components, and only a small number of technology specialists, so that we can swiftly allocate general developers to upcoming business needs… EGL is helping us achieve this goal…”
