Before you learn about anything in .NET, you should undertand how’s its structure. This chapter takes a brief look at Microsoft .NET and the Microsoft .NET Platform. It then describes the .NET Framework design goals and introduces you to the components of the .NET Framework Microsoft announced the .NET intitiative in July 2000

This report is the final product of a Committee on Earth Studies (CES) examination of technical and programmatic
issues related to the integration of research and operational Earth observation satellite systems in the support
of climate research (see Appendix A for the statement of task).
The Linguist’s Search Engine (LSE) was designed to provide an intuitive, easy-touse interface that enables language researchers to seek linguistically interesting examples on the Web, based on syntactic and lexical criteria. We briefly describe its user interface and architecture, as well as recent developments that include LSE search capabilities for Chinese.

Purpose of this document is to provide an architectural overview of CRM system. Through this document, project team and IT Department can have an overview and understand the whole system. They can know how CRM system will be developed and which systems CRM will have to integrate with.
This document also describes all constraints that the design of the system must follow to meet the business and maintenance requirements.
In the two decades since their invention, the heterogeneity of networks has expanded further with the
deployment of Ethernet, Token Ring, Fiber Distributed Data Interface (FDDI), X.25, Frame Relay, Switched
Multimegabit Data Service (SMDS), Integrated Services Digital Network (ISDN), and most recently,
Asynchronous Transfer Mode (ATM). The Internet protocols are the best proven approach to internetworking
this diverse range of LAN and WAN technologies.

There are several key aspects of GUI design that you need to consider when designing and implementing the GUI for your project. At a high level, they can be broken down into two main areas of focus:
1. Designing the GUI to be usable and friendly from the end user’s perspective. 2. Designing and implementing the GUI to be reliable, and maintainable from the programmer’s perspective.
This chapter will focus almost entirely on the first point—ease of use for the end user. We start with a very brief overview of the technical issues you probably want to address in implementing your...
Recovery Manager Features
Recovery Manager (RMAN) is an Oracle utility that you use to manage the backup, restore, and recovery operations on Oracle databases. RMAN has a powerful command language that is independent of the operating system.
Recovery Manager has a command-line interface. Oracle Enterprise Manager also provides a graphical user interface for the Recovery Manager. Recovery Manager can be used on databases of Oracle8 or later releases.
RMAN provides several features not available when you make user-managed backups with operating system commands.
MSC.ADAMS Full Simulation Package is a powerful modeling andsimulating environment that lets you build, simulate, refine, and ultimatelyoptimize any mechanical system, from automobiles and trains to VCRs and backhoes.
Concept of User Interface
The user interface is the part of the system that you see, hear and feel (look and feel)
Other parts of the system are hidden to you, for instance the database where information is stored.
Although users don’t see the hidden parts, they imagine to some extent what is going on ’behind the screen’.
When you use a computer, you give it orders, usually by means of the mouse and the keyboard.
The computer replies, usually by showing something on the screen or making sounds.
Bush posited Memex as “a device in which an individual stores all his books, records, and communications,
and which is mechanized so that it may be consulted with exceeding speed and flexibility. It is an enlarged
intimate supplement to his memory.” Memex was to be built into a desk with a keyboard, microphone, and
display surfaces. Its interface could copy photos or papers, or could be written on. However, “most of the
Memex contents are purchased on microfilm ready for insertion.
