Data: Lowest level of abstraction.

Information: Data that are processed to be useful, organized data.

Knowledge: Application of data and information, answers “how” questions.

Main types of IT support systems:

• MIS
• Office Automation Systems
• CAD/CAM
• Communication and Collaboration Systems
• Desktop Publishing Systems
• Group Support Systems
• Expert Systems
• Knowledge Management Systems
• Data and text mining
• BI
• Mobile Computing Systems

Text mining: Process of deriving high-quality information from text.

Cloud Computing: Delivery of computing as a service rather than a product, whereby shared resources, software, and information are provided to computer and other devices as a utility over a network.

(+) Access your data all time, a physical storage center no longer needed, payment when used, easily scalable

(-) Less control comes with handling over your data and information, dependence on a third party to ensure security confidentiality of data and information, long term dependence.

Virtualization: Creation of a virtual version of sth, such as hardware platform, operating systems, a storage device or network resources.

Saas: Instead of buying and installing expensive packaged entreprise apps, users access apps over a network, with an Internet browser being the only absolute necessity.

Database: Repository of enterprise data that business apps create or generate data. An organized logical grouping of related files.

DBMS: Programs used to create, manage, and access databases.

Data latency: The speed in which data is captures is referred to as data latency.

Data management: Structured approach for capturing, storing, processing, integrating, distributing, securing and archiving data effectively through their life cycle.

Data mining: Process of analyzing data from different perspectives and summarizing it into useful information.

Data quality: The degree of data accuracy, accessibility, relevance, timeliness, and completeness.

Data integrity: Trustworthiness of system resources over their entire life cycle.

Data warehouse: Specialized type of db that is used to aggregate data from transaction dbs for data analysis purposes, such as identifying and examining business trends, to support planning and decision making.

Characteristics of data warehouse:

• Organization
• Consistency
• Time variant
• Nonvolatile
• Relational
• Client/Server
• Web-based
• Integration
• Real-time

Problems in db systems:

• Data redundancy: Same data could be duplicated in several files.

Major categories of general data controls

è Physical controls

• Appropriate design of the data center
• Shielding against electromagnetic fields
• Good fire prevention, detection

è Access Control

• Using passwords, smart cards, signature voice, fingerprint or retina scan

Batch processing: Execution of a series of programs on a computer without manual intervention.

Risk management: Process of identifying, assessing, and reducing risk to an acceptable level.

Phishing: Is a way of attempting to acquire information such as username, passwords, and credit card details by masquerading as a trustworthy entity in an electronic communication.

Trojan horses: Malicious programs that provide illegal access to a network or account through network port.

BIA: Business impact analysis is an exercise that determines the impact of losing the support or availability of a resource.

Three layers of network security:

1^st layer->Perimeter security (Network layer security)

• Virus scanning, firewalls, IDS, Virtual private networking, DoS protection

2^nd layer->Authentication (Proof of identity)

• Username/pwd, pwd synchronization, PKI, tokens, biometrics, single-sign-on

3^rd layer->Authorization (Permission based on identity)

• User/group permissions, enterprise directories, enterprise user administrations, rules-based access control

Single sign-on: Property of access control of multiple related, but independent software systems.

Types of e-business transactions and models

• B2B: Both the sellers and buyers are business organizations.
• Collaborative commerce(c-commerce): Business partners collaborate (rather than buy or sell) electronically. Frequently occurs between and among business partners along the supply chain.
• B2C:The sellers are organizations and the buyers are individuals.
• C2C, B2B2C, C2B, Intrabusiness commerce.

Web analytics: Measurement, collection, analysis and reporting of internet data for purposes of understanding and optimizing web usage.

Adv and Dadv of single sign-on:

->ADV:

• Improves the effectiveness/timeliness of disabling all network/computer accounts for terminated users.
• Improves the admins’s ability to manage users and user configurations to all associated systems
• Reducing IT costs due to lower number of IT help desk calls about pwds
• Reduces phishing success, because users are not trained to enter password everywhere without thinking.

->DADV:

• Using only one SSO can introduce a single point of network failure.
• The SSO server and other host security must be hardened since weaknesses can now be exploited across the enterprise.
• Substantial interface development and maintenance may be necessary, especially in absence of industry-based standards.

3G&4G: 3G enabled faster data transmission speeds, greater network capacity and more advanced network searches. 4G most widespread, high-speed wireless services. Only available in limited areas.

Ubiquity: Attribute of being available at any location at any time.

Mobile banking security risks: Using 3^rd party applications instead of client apps offered by banks, automatic log-in or “remember-me”, storing account details in phone.

L-commerce: Location based,finding nearest ATM or FedEX drop box.

Web 1.0, 2.0 3.0: Web 2.0: Information sharing, interoperability, user-centered design, and collaboration on WWW. Web 3.0, semantic web, the computer is generating new information rather than humans. Evaluation of 3D web, tailor made, contextual or personalized search.

Then I found very very easy and fast solution, using NotePad++. To eliminate the duplicates you should follow these instructions:

1) Click TextFX –> TextFX Tools –> +Sort outputs only UNIQUE (at coulumn) lines

2) Select all your data

3) Click TextFX –> TextFX Tools –> “Sort lines …  ”

ABD’de yaşayan Türk girişimciler Cemil Özyurt ve Ömer Güneş’in girişimiyle Türkiye’de ofis açan Comodo’nun CEO’su Abdulheyoğlu, “Türkiye’deki amacım, sadece ürünlerimi pazarlamak değil. Bütün derdim ABD’den Türkiye’ye teknoloji transferini gerçekleştirmek” dedi. Türkiye’de güvenlik alanında Amerikalı ve Rus teknoloji firmalarının da bulunduğunu hatırlatan Abdulhayaloğlu, “Fakat çoğunluğu ürünleri getirip Türkiye’de satıyor, parasını kazanıp ülkesine geri götürüyor. Bizim hedefimiz burada teknoloji üretimini gerçekleştirmek ve Türkiye’den dünyaya satabilmek’’ diye konuştu.

Firstly, before starting multi-touch programming, you need to have an idea about WPF and xaml, therefore I strongly advise you to have this book Pro WPF in C# 2010. This book really explains every details about WPF and xaml with C# and also it has a chapter about multi-touch too. By using this book, you should also download the source codes and examples from the publisher’s web site.

After checking the book, you can look these web sites too:

http://www.wpftutorial.net/

http://drwpf.com/blog/

And then if you are ready to write some code, just wait and have a look at these web sites, which contain sample wpf applications. It will be very beneficial you to look sample codes, before programming

http://windowsclient.net/downloads/folders/wpfsamples/default.aspx?PageIndex=1

http://archive.msdn.microsoft.com/wpfsamples

And finally, http://blogs.msdn.com/b/jaimer/archive/2009/11/04/introduction-to-wpf-4-multitouch.aspx this web site really explains basics of wpf and multi-touch programming, and gives source code about multi-touch applications.

Good luck.

The solution is easy, because some samples in the pre-release versions of the Windows SDK referred to scenicanimation.h, but this file was renamed prior to release.  The RTM version of the Windows 7 SDK should refer to UIAnimation.h instead of scenicanimation.h. Thus in your sample code, just change the #include <scenicanimation.h> with #include <UIAnimation.h>

If you are using Visual Studio 2010 and trying to compile Microsoft’s hand on labs from PDC available on MSDN Code Gallery you will see this error, because Visual Studio 2010 requires these codes to be converted to the appropriate version for 2010, therefore, while converting there might be some errors that we can’t track easily.

Hence if you see this error, I will write couple of solutions;

• Before debugging, just clean the solution first =) Build>Clean, Build>Rebuild

• Solve it by setting “MSBuild project build output verbosity” from “Minimal” to “Diagnostic”    (Tools->Options…->Projects and Solutions->Build and Run)

I hope these will help to you.

After preparing our device for multi-touch programming, now it is time to discover structure and functions of the Windows Touch. I will provide many different links for developing multi touch programming.

• The first web site is of course Microsft’s web site, it firstly gives a quick overview about Windows Touch, and then gives detailed information about what you can do with Windows Touch, how you can develop or how can you improve your applications’ usability by inserting multi-touch functions. It also writes common errors while developing multi-touch applications, anyway, you should really learn everything in this web site before starting to programming. http://msdn.microsoft.com/en-us/library/dd317323(VS.85).aspx

• If you are not that much ‘reader’ person, you can also watch this useful video, which is about multi-touch API’s introduced in Windows 7 and WPF 4.0 comes from PDC session by Reed Townsend and Anson Tsao...

• What is more, there are also two later sessions from WinHEC 2008: Multi-Touch in Windows 7 Overview covers some basics and repeats information from PDC, while Multi-Touch Driver Development and Logo Compliance is more toward hardware developers.

• After finishing the information part, now it’s time for coding ! But I give one more advice for you =) before start to code, you should check out some code samples from hand on labs from PDC available on MSDN Code Gallery. Most of the code samples use C++, while tasks are getting more complicated it also uses C# too. I strongly recommend you to try these codes before starting your own project, because it higlightes main features of windows touch and gives useful code examples.

• http://msdn.microsoft.com/en-us/gg465116 : In this web site, you can find lectures about Gestures – Native Gestures – MFC Multitouch – .NET Multitouch – Native Multitouch – MFC

• More information in multi-touch and related technology can be found in the great NUI Group Forum.

If you really study on these links, developing a Windows Touch application will be much easier =)

If you are not sure whether or not your driver is installed successfully, you can open a paint and try to draw something at the sametime with your two fingers. Or open an internet explorer and try to zoom by moving two fingers apart and toward each other =)

With these two web sites, you can download the driver with respect to your device and install it easily.

• NextWindow’s Multi-Touch Screen Driver
• N-trig’s Multi-Touch download for Win7

What is more there is one project called Multi-Touch Vista, which also provides multi touch features. If you tried two web sites below and did not succeed, you can try this project via the following address: http://multitouchvista.codeplex.com/

And to install this project(because it is a little bit complicated and long) there is a video on youtube. Video is the older version of this project however you can follow the order of the executable files in this video and run it by your own. Because directories have changed but the files that are run in this video are all same. You can watch video from this link: http://www.youtube.com/watch?v=_maaH1gecxw

After installing your driver, you can start to explore Windows Touch features !

Here are some other areas in Windows 7 that were enhanced with multi-touch features:

• Panning with inertia is enabled “everywhere” where scrollbars exist.
• Paint
  • Choose a brush from the “brush gallery” and you can then multi touch finger paint.
• Games
  • Hearts/Solitaire have been optimized for touch
• Shell
  • Windows Snapping (Aero Snap) with Touch
  • Aero Peek with Touch
  • Taskbar Jump Lists with Increased spacing

  • Panning
  • Drag Menu (Address Bar) with Increased Spacing
  • Increased Spacing for Favorites with Touch
  • Gesture (Zoom, Panning, Flicks back and forth)
• Windows Live Photo Gallery
  • Gesture support in the Viewer
