RESUME PERANCANGAN BASIS DATA II

Ketergantungan Program dan Data:
- Setiap program aplikasi harus memiliki data sendiri – Memungkinkan duplikasi data
- Setiap program aplikasi harus memiliki fasilitas pengelola meta data untuk setia file yang digunakan
- Setiap program aplikasi harus memiliki fungsi untuk membaca, menulis, mengubah dan menghapus data
- Tidak ada koordinasi data yang sama antar aplikasi
- Sulit membakukan format-format file

Pendekatan Program Basis data :
- Sebagai pusat respitori data bagi seluruh organisasi
- Data dikelola oleh suatu sistem pengendali
- Data disimpan dalam format yang baku dan mudah dimengerti

Keuntungan Penggunaan Basis Data :
- Controlling Redundancy yaitu kemampuan mengontrpl suatu sistem untuk tetap berfungsi dengan normal walaupun terdapat elemen yang tidak berfungsi.
- Restricting unauthirized access yaitu setiap pengguna mempunyai hak istimewa tersendiri, seperti contoh diijinkannya salah satu user untuk retrieve data.
- Provides persistents storage for data stuctures yaitu sistem basis data berorientasi objek. Misal tipe record dalam pascal atau definisi kelas di C++.
- Permits Inferencing adalah Sistem database deduktif memiliki kemampuan mendefinisikan rule deduksi untuk menginfer informasi baru.
- Multiple user interfaces adalah Berbagai macam interface untuk berbagai pengguna.
- Represent complex relation amongst data adalah kemampuan untuk mempresentasikan relasi yang kompleks demi memmudahkan pengguna.
- Enforcing integrity constraints yaitu kemampuan untuk membuat suatu integrity constraint. Tipe yang paling sederhana dari integrity contraint adalah menspesifikasikan tipe data untuk setiap item data.
- Provide backup & recovery yaitu ika sistem komputer gagal saat sedang mengupdate program, sub sistem recovery bertanggungjawab untuk memperbaiki atau memastikan basis data direstore ke keadaan sebelum program dieksekusi kembali.

Pengguna Basis Data :
- Administrator Database
- Progammer Database
- End User = ~ Casual end user
     ~ Parametric user
     ~ Sophisticated user
     ~ Stand-Alone user
- Software Engineer

Kapan Perlu Menggunakan Basis Data :
- Data berupa data ‘bisnis’: jumlahnya besar, perlu di-update.
- Banyak bagian data yang homogen
- Data relevan untuk jangka waktu yang cukup lama
- Data digunakan secara simultan oleh banyak pengguna

Kapan Kita Tidak Perlu Basis Data?
- Jika basis data dan aplikasi sangat sederhana, terdefinisi dengan baik, tidak akan berubah
- Adanya kebutuhan real time tertentu yang rigid, yang tidak dapat dipenuhi karena DBMS overhead
- Akses bersama ke suatu data tidak diperlukan

Kapan Basis Data Tidak Dapat Digunakan?
- Jika sistem basis data tidak dapat menangani kompleksitas data karena keterbatasan pemodelan
- Jika pengguna perlu operasi khusus yang tidak dapat dipenuhi oleh DBMS

1. Data yaitu fakta dari berbagai sumber di dunia nyata. Data diolah guna memberikan informasi bagi pengguna serta mendapat kan pengetahuan yang baru ( informasi yang bersifat tersembunyi )

3. Basis Data merupakan Kumpulan data terorganisir dan disimpan secara sistematis berdasarkan suatu struktur hubungan dan memiliki kaitan satu dengan lainnya yang dibuat guna memenuhi kepentingan banyak pemakai pada suatu organisasi
4. Definisi sistem yaitu sekumpulan elemen-elemen yang mempunyai tujuan yang sama.
5. Sistem Basis Data merupakan Sekumpulan Basis Data dengan para pemakai yang menggunakan basis data secara bersama-sama.
6. metadata yaitu sebuah data yang mendefinisikan atau menjelaskan sebuah data. 
7. Tujuan Basis Data Yaitu :
- Mencegah redudancy dan inconsistency data
- Menjaga integritas data 
- Independensi data ( data tidak bergantung pada data yang lain ) yaitu jika salah satu data di hapus maka tidak berefek ke data lain
8. Database Management System (DBMS) adalah suatu sistem yang dirancang untuk mengelola suatu basis data dan menjalankan operasi terhadap data yang diminta banyak pengguna. DBMS juga merupakan general purpose software yang berguna untuk :
- Mendefinisikan
- Mengkonstruksi
- Memanipulas

9. Terdapat berbagai macam aplikasi basis data, salah satu contohnya seperti : 
- MySQL 
- ORACLE
- TERADATA
10. Sistem Berkas merupakan suatu system untuk mengetahui bagaimana cara menyimpan data dari file tertentu dan organisasi file yang digunakan.
11. Pendekatan basis data berkembang karena kelemahan pendektatan sistem berkas (file system) yang berkembang sebelumnya. serta satu file berhubungan dengan satu program atau lebih.
12. Masalah pada Sistem Berkas :
- Adanya ketergantungan antara program dan data
- Duplikasi data
- Data kurang terstruktur (berupa flat file)
- Biaya pemeliharaan tinggi.
13. Langkah Kerja Sistem Database yaitu = STORAGE (database) ↔ DBMS ↔ progam aplikasi ( DBMS Mengelola sumber daya data sebagaimana OS mengelola sumber daya perangkat keras) 
14. Pendekatan Basis Data : 
- Pusat repositori data bagi seluruh organisasi
- Data dikelola oleh suatu sistem pengendali
- Data disimpan dalam format yang baku dan mudah dimengerti.

Hello guys. How are you today? I hope you’ll be fine. On this week I want to write topic about “Your top recommendations for things to do in your town”
Last year, I and my family going home to the city of Magetan. The city is located in the East Java province. In the city is located on the slopes of Mount lawu, so that when the morning air in the city was very cold. So when I got there, every morning I have to boil the water for the purpose of bathing hihhhihi.
When I was in the city of Magetan. I visited some tourism destination. An example of such as the Telaga Sarangan, and waterfalls on the slopes of Mount Lawu. When I was in the Telaga Sarangan, there is a variety of interesting activities. As rose horses, rent a speed boat to surround the pools, and there was food sate rabbits. The price for the horse ranges from Rp60.000 up to 1x rotation around the Telaga Sarangan. While the price for the speedboat limits Rp90.000/1x rotation. meal prices are classified as expensive, but the price is reasonable with the beauty of the Telaga Sarangan.

In addition to touring in the Telaga Sarangan, i pulls harbored at the waterfalls Lawu Mountain. To reach into the waterfall. We must go hiking in the hills around 30 minutes. When until there, fatigue you will be reasonable with the enchantment of the waterfall. So on this occasion I want to recommend to make a tour in the city of Magetan.

Thank you for your attention.

     I will explain A letter to my younger self. When I still studied levels of education junior high school, I have times of darkness. Many memories that I will never forget when sitting on a bench junior high school. Few years ago, my school in the city of Surabaya, East Java. When I go to school there, I never skipped school for 1 weeks. I willingly skipped school only in order to play games online. However,  My parents know it.  Until the genesis, I made a post that i stick on my clothes cupboard inscribed with “Remember God, Create a happy parents, and never do it again”.

     And then, A letter for ten years later is “If you now have become the successful, Don’t forget the God, Always create a happy parents with your sister, Stay humblee. And when at this time you have been married. Learn to complement each other when you housekeeping”

That is the only thing of which I can mention. Thank you for your attention.
