Technical Information
General
ETR.Net was designed based on best practices and patterns. The software is split into several logical layers, each providing specific services to the other layers within the software. ETR.Net was designed to interact with Microsoft Access and/or Microsoft SQL Server (or MSDE) databases by default, but can be modified to interact with other database platforms by modifying the Data Access layer only (i.e. other layers are not adversely affected).

ETR.Net is programmed in Microsoft Visual Basic.NET and currently operates using the Microsoft .Net Framework v2.0. Past versions of ETR.Net operated using the .Net Framework v1.0 (i.e. v.1.0.3705).


The Microsoft .NET Framework
The .NET Framework is a new computing platform that simplifies application development for standalone and highly distributed systems. Some key features of applications written for the .NET Framework include:

  - rapid application development owing to a comprehensive development tool set
  - excellent user interface customization features - globalization (i.e. multi-language support)
  - integrated XML and web service support
  - rich code and application security features
  - extensive mobile features, (e.g. pocket pc and/or mobile phones)
  - same code across multiple devices (e.g. desktop, web, pocket PC and mobile phone)
  - copy and paste deployment (if .NET Framework is already installed)
  - no DLL registration (in windows registry) means that DLL version conflicts do not occur


ETR.Net Security
Owing to the confidential nature of the data stored in the ETR.Net database, some security measures have been implemented in order to improve security to the highest degree possible. For example ETR.Net makes use of the Rijndael encryption algorithm with a 256 bit key size in relevant features (e.g. data dispatch, etc.).

The Rijndael algorithm can use key sizes of 128, 192, or 256 bits and block lengths of 128, 192, or 256 bits. The Rijndael cipher is faster than the block ciphers RC2, DES and 3DES. Rijndael also has the largest key space of the algorithms.


ETR.Net Hardware and Software Requirements
ETR.Net requires the Microsoft.NET Framework and Microsoft Data Access Components (v2.7 or higher) in order to operate correctly. Both of these are installed automatically by the ETR.Net setup and deployment package (or installation CD).

The following hardware and software pre-requisites are required for installation of the Micrsoft.NET Framework (and thus for ETR.Net):

 - Windows 98 (SE), Millenium, NT4*, 2000*, XP, 2003 or Vista
 - Internet Explorer v5.01 or higher (v6.0 usually included on installation CD)
 - 900MHz processor (1.4GHz or higher recommended)
 - 128MB RAM (256MB or higher recommended)
 - CD/DVD ROM drive (if installing from CD)
 - 100MB free hard drive space

( * Service packs may be required in some cases).
