Rapid Application Development with RelaX-db

Rapid Application Development with RelaX-db

RelaX-db is a set of tools & libraries for the RelaX data model to enable Rapid Application Development and Rapid Prototyping

Components:

define

Define the tables and complex objects and generate the sql-ddl statements for various database systems with the "rxmodel"-tool.

generate

define the form based on the model and generate the html-code for further refinement with the "rxgenerate"-tool

operate

operate the final html-form with a comprehensive set of functions bundled in the "rxclient"-library

serve

support the database functions and the file services for the AJAX-calls with the "rxserver"-components

Facts

Facts

state of the art design and slim implementation come to a powerful system

fast

RelaX-db generates a single page application with slim AJAX-calls. Users experience fast responses with a minimum of server interaction

efficient

The app-designer specifies the structure of the database, the complex objects for the functions and the structure of the form. After these steps the app is running and can be tested

user friendly

The system features numerous comfort features like master-detail-interaction, lookups, calculated fields, schema trekking and arbitrary query parameters

compatible

RelaX-db supports major browsers like Chrome, Firefox and IE. It interacts with ORACLE, SQL-Server and MySQL on the database side. You only need a Node-JS-installation for the server components

RelaX Data Model

RelaX Data Model

RelaX means Relational eXtension

The RelaX data model combines multiple tables of a relational model into a complex object. The following picture lists 4 complex objects:
ordr, article, cust and agr

complex objects

Complex objects are divided into two sections:

edit

Edit Tables are tables, that can be updated. They form a tree in a master-detail-form like order-items

lookup

Each of the Edit Tables can have Lookup Tables in the form of a tree. Aliases allow lookups from different source tables

Supported Patterns

The structure of Complex Objects and corresponding User Interface Patterns enable Rapid Application Development with a minimum of declaration effort

navbar

A navigation bar is automatically generated from the list of complex object. Each complex object defines a navbar function.

search

Search and join logic of for the select statements is automatically generated from the structure of the relevant complex object.

lookup

Lookups enable comfort search options and key binding for alternative key fields. Lookups can be triggered by simple html-attributes.

resolve

Binding of an object to a lookup table can be achieved through lookups attributes. Attributes, which depends on the new master are resolved automatically on change.

calculate

Calculated attributes can be used like singular database attributes.

schema trekking

Navigation between the objects/functions can be achieved through simple calls, e.g. from an order to the associated customer

inactive/log

The system sets master objects with active details to inactive on delete. After setting a customer to inactive, no more orders can be bound to this customer.

file upload/download

Files can be treated as normal attributes and con be uploaded, downloaded and displayed in the web page.
