ASP.NET
What is ASP.NET? ASP is an acronym for Active Server Pages. "NET" refers to technology
that is suited for internet development and solutions. ASP.NET is arguably the leading
web framework for building interactive web sites. Application of this technology
provides faster performance and tighter security.
ASP.NET provides enchanced security with it's "built-in" Membership Application
Programming Interface (API) module. This module allows for building a user registration
system that stores user information in an SQL SERVER database or Active Directory.
Thus, multiple users may be assigned different roles with specific "web paths" for
each type of user. Also, both the username and password are encrypted in the database
for added security.
Microsoft's Visual Studio is an Integrated Development Environment (IDE) used by
System Engineering Design to build ASP.NET applications. It provides the flexibility
to build N-tier applications allowing for a separation of the presentation layer,
the business logic layer and the data access layer. This means web pages,
business rules for processing data, and the type of relational database used (DB2/UDB,
SQL Server, Oracle) may be changed without impacting the entire application.
System Engineering Design builds N-tier applications.
An additional advantage of ASP.NET is the ability to cache data, a web page or part
of a web page. This enhances the web browsing experience by providing faster web
page loading and data retrieval.
System Engineering Design applications are coded using the VB.NET programming language
or the C# programming language. SQL Server is the database of choice.
ASP.NET handles 1.5 billion page views per day and 2.3 million concurrent users

SQL SERVER
What is SQL SERVER? SQL is an acronym for Structured Query Language. "SERVER" refers
to data that is stored and retrieved from a server. SQL SERVER is a database component
useful for many applications. It is ideally suited to an internet application where
"permanent" storage is needed.
SQL SERVER is a full-bodied database. This means that a database administrator can
set indexes and define various column types (date, numeric, text, etc). Also, since
it's a relational database, data tables can be associated to each other. SQL is
the common language used for relational databases. This language is used to build
or modify data structure and to create, read, update or delete records.

Server hardware purchase and installation is the responsibility of the agency. Server
software and software installation (such as SQL Server database and the Server Operating
System) that are required for the Contract Invoicing System to function properly
will be the responsibility of the agency. Server security will be the responsibility
of the agency. If the agency does not have the technical staff to accomplish these
actions, System Engineering Design will provide this expertise from a pool of knowledgeable
consultants. The agency will be responsible for all hardware and software costs
including the salaries of persons needed to complete the installation of hardware
and software. Agency is defined as the party purchasing the Contract Invoicing System
software.
