Windows 7 Activation Steps

noreply@blogger.com (Anonymous) — Sat, 31 Dec 2011 04:49:00 +0000

What is Windows activation?

Activating Windows 7 installation is in a way registering Windows 7 operating system of yours and making it legal.

Since Microsoft is keeping their rights on their various products including Windows products using the genius activation method, as a Windows 7 user, you should also activate Windows 7 copy of your own within a given period using one of different methods.

Why activating Windows 7 is important?

Microsoft operating systems had this feature on Windows Vista editions as well as on Windows 7 editions with different Windows 7 Build 's until its RTM release is published.

And windows activation which is not completed in the given period of time disables some Windows features and prevents you to use all properties of your system after the activation period.

Also you may not be able to update your system with the recent product updatsd from Microsoft.

So to make sure that you can benefit from all the feaures and enhancements of your Microsoft Windows 7 operating system, give priority to activate Windows7 as early as possible.

If you have already tried to activate Windows 7 copy, but failed and getting "This copy of Windows 7 is not genuine" warning then you can refer to Windows 7 troubleshoot article Windows 7 Activation - This copy of Windows 7 is not genuine for possible solution suggesstions.

Let's continue with Windows 7 activate process steps.

How to Activate Windows 7 manually ?

If you did not activate Windows 7 during your Windows 7 installation, you can start activating Windows 7 manually.

You can see for Windows 7 activation you have limited time to complete activating Windows 7 installation.

You can see how much time remaining for you to activate Windows7 for different Windows 7 Build numbers when you open the System control panel screen at the bottom of the panel view.

To open the below System Control Panel screen, you can open the Control Panel, then select System and Security menu item and select the System control panel view.

If you have not activated Windows 7 Ultimate Edition after you have installed your Windows 7 operating system, you will see the Windows activation section at the botom of the Control Panel screen.

When you have an online internet connection, you can start activating Windows process manually by clicking the "Activate Windows now" link.

On the Windows Activation screen in order to activate Windows 7 Build 7000 for instance, you are reminded how many days are there still for activating Windows 7 Ultimate RC operating system.
Activating Windows 7 will enable you to use all Windows features after the activation period is ended.
So to make sure, if you have an active online internet connection, go on for next steps by selecting the option "Activate Windows online now".

This screen displays the message to the user about the product key is being veried. So if the activation can connect to Microsoft via internet connection and manages to validate the product key without any problem you will be redirected to the last screen of the Windows Activation wizard.
This is the activation step the question of "How to register Windows 7" is answered.
If the system can not reach to the internet due to network errors or a valid internet connection, you will be prompted to define and build an internet connection.

In the below screen Windows 7 users can see the result of a successful Windows activation.
It is stated that your copy of Windows is verified and with a valid copy of Windows 7, you are eligible to recieve all available updates and product support from Microsoft.

As you can see in the above explained steps Windows 7 activation is simple and straight-forward unless you have a valid copy of Windows 7.

Generally you will not face a problem during Windows 7 activation of your Windows copy.
If you experience a problem while trying to register Windows 7 via activation, then you can call the Microsoft Support phones or start activation using phone procedure and talk to a support engineer to help you with your Windows 7 activation problem.

SISTEM INFORMASI TRAVEL BERBASIS WEB (DFD)

noreply@blogger.com (Anonymous) — Thu, 29 Dec 2011 06:00:00 +0000

Pembuatan system travel ini, bertujuan untuk melengkapi tugas yang diberikan yaitu mengenai data flow diagram dari system informasi travel. Disini, yang saya ilustrasikan adalah system program yang berbasis web.

Berikut adalah diagram context (level 0) dari system informasi travel:

Di sini, saya membuat empat entitas dalam system, yaitu:

· Admin

· Operator

· Driver

· Custumer

Admin disini memiliki hak akses tertinggi, sehingga dia bisa mengontrol semua user yang ada dibawahnya, seperti user operator dan driver. Tapi dalam system ini, admin tidak di buat untuk bias menjalankan semua operasi yang ada, hanya bisa digunakan untuk memanajemen user yang lain. User admin ini biasanya digunakan untuk seorang yang melakukan pemeliharaan (maintenance) system.

Kemudian operator, yang entitas ini akan melakukan operasi-operasi seperti memanajemen driver yaitu menambah user driver, mengedit data user atau menghapus user driver. Memanajemen jadwal yaitu mengatur penjadwalan keberangkatan yang nanti nya informasi ini akan ditampilkan disistem untuk ditujukan kepada costumer dan driver. Memanajemen kendaraan (mobil) yaitu membuat daftar jenis kendaraan yang ada dan memonitor ketersediannya mobil(kursi), dan memverifikasi pemesanan yaitu saat pemesan akan berangkat maka pemesan harus melihatkan atau konfirmasi ke operator dengan memperlihatkan bukti pemesanan.

Entitas driver, hanya bisa beroperasi untuk melihat informasi mobil yang akan digunakan nya dan jadwal keberangkatan nya dengan memasukkan username terlebih dahulu yang username tersebut telah dibuat oleh operator ataupun oleh admin. Terakhir entitas costumer, entitas ini yang digunakan pemesan untuk order tiket melaui system.

Entitas	Data masuk	Informasi keluar
Admin	· Login · Data operator · Data driver · Data costumer	· Informasi operator · Informasi driver · Informasi costumer · Informasi pemesanan · Informasi mobil · Informasi keberangkatan
Operator	· Login · Data driver · Data costumer · Data mobil · Data keberangkatan · Verifikasi pemesan	· Informasi driver · Informasi costumer · Informasi mobil · Informasi kebernagkatan · Informasi pemesanan
Driver	· Login	· Informasi mobil · Informasi keberangkatan
Costumer	· Registrasi · Login · Pemesanan tiket	· Informasi account · Informasi mobil · Informasi pemesanan · Informasi keberangkatan · Bukti pemesanan

Disini saya akan menjelaskan secara singkat proses-proses dari DFD level 1 yang saya buat. Pertama pada OPERATOR, operator harus login terlebih dahulu agar bisa menjalankan semua fungsi nya. Operator login menggunakan username dan password yang telah dibuat oleh user ADMIN. Setelah login, barulah operator dapat menjalankan fungsi-fungsinya seperti manajemen data driver, manajemen data mobil, manajemen jadwal dan verifikasi pemesan. Di sini operator bisa mengontrol user driver, menambah, edit dan menghapus daftar user driver. Pada manajemen data mobil, operator mengatur daftar jenis-jenis mobil yang tersedia dan siap pakai yang data nya tersebut akan tersimpan pada srorage dan data ini dapat dilihat oleh driver dan costumer. Dan fungsi selanjutnya manajemen jadwal, yaitu mengatur jadwal keberangkatan yang nantinya akan ditunjukkan kepada calon pemesan dan driver juga dapat melihatnya..

Fungsi selanjutnya adalah memverifikasi customer (penumpang) yang membawa bukti pemesanan yang didapatnya setelah customer melakukan pemesanan. Jadi, ketika customer memesan tiket pada bagian akhir diberikan bukti pemesanan yang bisa dicetaknya, yang kemudian bukti tersebut yang akan diverifikasi tadi oleh operator.

User admin hanya mengontrol user operator dan driver, juga bisa melihat semua informasi-informasi yang ada. Begitu pun user driver, hanya berfungsi sebagai sarana para driver untuk mengetahui mobil mana yang mereka gunakan dan jadwal keberangkatan nya.

Proses system ini dimulai ketika seorang costumer memesan tiket melaui system, ia mengisi data-data pemesanan setelah ia melihat jadwal-jadwal yang ada dan ketersedian mobil pada system. Yang mana informasi ini di manajemen oleh operator sebelum nya. Setelah costumer selesai mengisi data pemesanan, maka data tersebut tersimpan di storage yang nanti nya data tersebut dapat dilihat dan diolah lagi oleh operator. Selanjutnya costumer mendapat menetak informasi pemesanan sebagai tanda bukti yang nanti nya bukti tersebut akan diverifikasi.

Entitas	Proses data	Data store
Admin	Login;manajemen operator;manajemen driver;manajemen costumer	Penyimpanan data admin; penyimpanan data operator; penyimpanan data driver; penyimpanan data costumer.
Operator	Login;manajemen driver;manajemen costumer; manajemen keberangkatan; manajemen mobil; verifikasi	penyimpanan data operator; penyimpanan data driver; penyimpanan data costumer; penyimpanan data keberangkatan; penyimpanan data mobil; penyimpanan data order
Driver	Login	Penyimpanan data driver; penyimpanan data mobil; penyimpanan data keberangkatan
Costumer	Registrasi; login; pemesanan.	penyimpanan data mobil; penyimpanan data keberangkatan; penyimpanan data order

Selanjutnya, setelah terbentuk DFD level 1, dapat dibentuk DFD level 2, level 3, level 4 dan seterusnya. DFD ini dibuat hanya apabila diperlukan saja, maksudnya apabila proses pada DFD level 1 masih memerlukan penjabaran lagi.

Diagram level 2 merupakan dekomposisi dari level 1 karena pada level 1 terdapat proses yang masih bisa diperinci, maka dibuatlah diagram level 2. Berikut merupakan DFD level 2:

1. Level 2 untuk proses 2 (manajemen driver)

Pada level 2 ini untuk proses 2 (manajemen driver) terdapat 4 proses pendekomposisian dari proses manajemen driver, antara lain : tambah driver, hapus driver, edit driver dan lihat driver.

Sistem Informasi travel level 2 proses 2.0

2. Level 2 untuk proses 3 (manajemen mobil)

Pendekomposisian proses manajemen mobil dibagi ke dalam 4 proses yang melibatkan terminator admin atau operator, antara lain : tambah mobil, edit mobil, hapus mobil dan lihat mobil.

Sistem Informasi travel level 2 proses 3.0

3. Level 2 untuk proses 4 (manajemen keberangkatan)

Pendekomposisian proses manajemen keberangkatan dibagi ke dalam 4 proses yang melibatkan terminator admin atau operator, antara lain : tambah jadwal keberangkatan, edit jadwal keberangkatan, hapus jadwal keberangkatan dan lihat jadwal keberangkatan.

Sistem Informasi travel level 2 proses 4.0

4. Level 2 untuk proses 5 (verifikasi)

Pendekomposisian proses verifikasi dibagi menjadi 3 proses yang melibatkan terminator operator, antara lain: verifikasi pemesanan, hapus pemesanan, dan lihat pemesanan.

Sistem Informasi travel level 2 proses 5.0

5. Level 2 untuk proses 6 (manajemen operator)

Pendekomposisian proses manajemen keberangkatan dibagi ke dalam 4 proses yang melibatkan terminator admin, antara lain : tambah operator, edit operator, hapus operator dan lihat operator.

Sistem Informasi travel level 2 proses 6.0

6. Level 2 untuk proses 7 (manajemen keberangkatan)

Pendekomposisian proses manajemen keberangkatan dibagi ke dalam 4 proses yang melibatkan

terminator admin atau operator, antara lain : tambah costumer, edit costumer, hapus costumer dan

lihat costumer.
