A traditional application server

• Often http-based (http requests)

• Unidirectional, because of the http protocol: only the client makes requests, server events being emulated (e.g.: by using timers)

• Caries the business logic in multi-tier architecture (this we will keep)

Concept Application Server

• concept:// based

• The concept:// protocol is bidirectional, enabling real time server events

• Caries the business logic in multi-tier architecture

• Also, can handle http://-based applications as a feature not as a purpose

• Cross-platform, open source, interoperable

Concept Application Server –System architecture

CAL= Concept Assembly Language

Interface level

• CAS exchanges messages with Concept Client

• Messages run from client to server and from server to client, similar to win32 messages

• concept:// is secured

• CAS is powered by Concept Programming Language (with hundreds of classes and thousands of helper functions)

Concept Programming Language

• Strict object-oriented

• Traditional syntax, similar with Java, C#, C++

• Hybrid interpreter/virtual machine

• Produces binary code OS-independent

• Exceptions, properties and all the typical things you’re used with

• Rich framework

• Has debugger and on-line IDE called CIDE (open source), written in Concept

How does CIDE look ?

Design view - glade

Remember, it’s on-line

• After installing CAS on your system, you just type in your browser:

concept://localhost/CIDE/cide.con

concept://…/CIDE

• Comes with tools like

– Design view with glade

– Syntax highlight and code completion with scintilla

– Team chat

– SQL Panel

– Integrated framework help

– a deployment system

– Integrated debugger and web-debugger

The internal messaging system

• CAS has an internal messaging system that allows a web application to communicate in real time with a concept:// application

• This is useful when we have a front-end traditional web application and a backend concept:// application. (for example orders from a website).

Security

• Managed by an RSA/AES system, similar to TLS

• In about two months will switch to TLS

GyroGears

• Automatically generate the application, the framework and the CIDE project

• Builds an abstract data layer (no direct access to the database is needed)

• Dramatically reduces the development time for cloud data-driven applications

• Reduces the bug probability

• Generates optimal code

GyroGears (cont)

• Handles complex data types like multimedia (video/audio streaming)

• Automatically generates reports

• Automatically writes the help pages based on language templates

• Can be installed for free but not open source(yet)

• Generates XML export/import interfaces

• Can create both concept:// and http:// applications

A sample application

• 20 min

A sample http:// application

By using GyroGears you can create complex http://-based application in no time.For this sample, about 10 to 14 hours of work were needed, mostly for the UI.

How it works

• The developer defines the entities and properties (similar to tables and columns), but more high level. Some data types are:

– multimedia – can keep and stream video/audio

– picture – can keep pictures, resize them, cache various sizes

– string types

– relations

How it works (cont.)

• The developer defines the behavior and restriction for a given data type

• Define the search fields, the indexed data (indexes are built using Xapian or Lucene)

• Generate advanced reports using an XML-style language

• Define basic activities and workflows

• Generate the CIDE project

GyroGears will generate

• The entire cloud application (concept:// and/or http://)

• Normalizing queues for videos

• Indexing queues for text

• The help pages for your application (in English, for any other language, you can create a template)

• Language tables (XML, for multi-lingual support)

• Reports

• XML schemas for export/import and “translation” scripts for importing from other applications

• Framework for traditional development (if necessary)

The Gyro-generated framework

• Additional layer for accessing the database (an abstract layer)

• Low bug probability

• Minimizes the development time (if used as an independent library)

• With many methods for accessing data, eg:

var []result=Company::GetByName(“RadGs”);

Fun things

• In Concept is easy to write virtually anything.

• For example, a browser using the webkit-gtklibrary.

• Or a PDF reader using the included popplerlibrary, or maybe a video database using ffmpeg …

• All is included in the Concept distribution, you just need to play !

Thank you, kind developers!
