Apakah "Big Data"? (What Is "Big Data"?)

Data adalah "Kuantitas, karakter, atau simbol dengan pengolahan yang dilakukan oleh komputer, yang dapat disimpan dan ditransmisikan dalam bentuk sinyal listrik dan dicatat pada medan magnet, optik, atau mekanis media perekaman."

Jadi, "Big Data" adalah istilah yang digunakan untuk menggambarkan pengumpulan data yang sangat besar dalam ukuran namun tumbuh secara eksponensial dengan/berdasarkan waktu. Singkatnya, data tersebut sangat besar dan kompleks yang tidak ada alat manajemen data tradisional yang dapat menyimpan atau memproses secara efisien.

Kategori "Big Data" : 

1. Structured (Terstruktur)
   Data yang dapat disimpan, diakses dan diproses dalam bentuk format tetap disebut sebagai data 'terstruktur'. Selama periode waktu tertentu, para pakar dalam ilmu komputer telah mendapatkan kesuksesan besar dalam mengembangkan teknik untuk bekerja dengan jenis data seperti ini (di mana format data dikenal lebih dahulu) dan juga menurunkan nilai dari data itu. Namun, sekarang, kita memiliki masalah ketika ukuran data tersebut tumbuh pada tingkat yang sangat besar, total ukuran data meningkat menjadi zettabyte.
   
   *10²¹ bytes sama dengan 1 zettabyte atau satu miliar terabytes.

Cara Tepat Memilih Tool Selenium Berdasarkan Kebutuhan

Tool

Alasan

Selenium IDE

Hal-hal yang diperlukan untuk mempelajari tentang konsep-konsep pengujian otomatis dan Selenium, yaitu:        -  Perintah Selenese seperti type, open, clickAndWait, assert, dll        -  Pencari seperti id, nama, XPath, css selector, dll        -  Running disesuaikan kode JavaScript menggunakan runScript        -  Mengekspor uji kasus dalam berbagai format. Hanya bisa simple-test dan tanpa perlu mengetahui dasar pemrograman. Membuat uji kasus sederhana dan uji suite yang dapat di- ekspor kemudian ke RC atau WebDriver. Menguji aplikasi web terhadap Firefox saja.

Pengantar WebDriver & Perbandingan dengan Selenium RC

Apa itu WebDriver?
WebDriver adalah kerangka otomatisasi web yang memungkinkan Anda untuk melaksanakan tes Anda terhadap browser yang berbeda, bukan hanya Firefox (seperti Selenium IDE).

WebDriver juga memungkinkan Anda untuk menggunakan bahasa pemrograman dalam menciptakan skrip uji Anda (tidak mungkin di Selenium IDE). Anda sekarang dapat menggunakan operasi kondisional seperti kasus beralih if-then-lain atau anda juga dapat melakukan perulangan seperti do-while. Bahasa pemrograman yang didukung oleh WebDriver :

Tutorial Selenium [2 - Cara Instalasi Selenuim IDE & FireBug]

Instalasi Selenium IDE

• Koneksi Internet

• Mozilla Firefox (http://www.mozilla.org/en-US/firefox/new)

1. Buka Firefox yang sudah diinstall, dan buka link ini  http://seleniumhq.org/download/ . Di bagian bawah Selenium IDE, klik pada link yang menunjukkan nomor versi saat ini.
2. Untuk keamanan, notifikasi Firefox akan muncul. Klik "Allow."
3. Tunggu sampai Firefox selesai men-download dan kemudian klik "Install Now."
4. Tunggu sampai instalasi selesai. Pada jendela pop-up, klik "Restart Now."

• Dengan menekan Ctrl+Alt+S

• Dengan menekan Firefox menu button > Web Developer>  Selenium IDE

Tutorial Selenium [1 - Pengantar]

Apakah Selenium?

Selenium adalah software (open source) pengujian otomatis  untuk aplikasi web di browser dan platform yang berbeda. Hal ini sangat mirip dengan HP Quick Test Pro (QTP), hanya saja Selenium berfokus pada mengotomatisasi aplikasi berbasis web.

Selenium tidak hanya alat tunggal tetapi rangkaian software, masing-masing melayani kebutuhan pengujian yang berbeda dari sebuah organisasi. Ia memiliki empat komponen, antara lain : 

• Selenium Integrated Development Environment (IDE)
• Selenium Remote Control (RC)
• WebDriver
• Selenium Grid

Library Untuk Membuat Grafik Pada Netbeans

Agar dapat membuat grafik/chart pada netbeans (java), maka dibutuhkan beberapa library
Diantaranya yaitu :

1. JFreechart
2. JCommon

Library-library tersebut dimasukkan pada netbeans dengan cara :
Pada menu tab pilih Tools->Libraries..
Kemudian tekan tombol Add Jar/Folder
Masukkan library-library yang telah anda download
Kemudian Tekan "OK"

Selamat Mencoba :D

2 Grafik / Chart Dengan JFreeChart Pada Java

Hal yang pertama kali dilakukan yaitu membuat sebuah class yang berfungsi untuk membuat chart/grafik
Pada kali ini saya akan memberi nama class tersebut class DualAxisDemo1


package demo;

import java.awt.Color;
import java.awt.Dimension;
import javax.swing.JPanel;
import org.jfree.chart.*;
import org.jfree.chart.axis.*;

public class DualAxisDemo1 extends ApplicationFrame
{

public DualAxisDemo1(String s)
{
super(s);
JFreeChart jfreechart = createChart();
ChartPanel chartpanel = new ChartPanel(jfreechart);
chartpanel.setPreferredSize(new Dimension(500, 270));
setContentPane(chartpanel);
}

private static CategoryDataset createDataset1()
{
String s = "S1";
String s1 = "S2";
String s2 = "S3";
String s3 = "Category 1";
String s4 = "Category 2";
String s5 = "Category 3";
String s6 = "Category 4";
String s7 = "Category 5";
String s8 = "Category 6";
String s9 = "Category 7";
String s10 = "Category 8";
DefaultCategoryDataset defaultcategorydataset = new DefaultCategoryDataset();
defaultcategorydataset.addValue(1, s, s3);
defaultcategorydataset.addValue(2, s, s4);
defaultcategorydataset.addValue(3, s, s5);
defaultcategorydataset.addValue(4, s, s6);

return defaultcategorydataset;
}

private static JFreeChart createChart()
{
JFreeChart jfreechart = ChartFactory.createBarChart("Dual Axis Chart", "Category", "Value", createDataset1(), PlotOrientation.VERTICAL, false, true, false);
jfreechart.setBackgroundPaint(Color.white);
CategoryPlot categoryplot = (CategoryPlot)jfreechart.getPlot();
categoryplot.setBackgroundPaint(new Color(238, 238, 255));
categoryplot.setDomainAxisLocation(AxisLocation.BOTTOM_OR_RIGHT);
CategoryDataset categorydataset = createDataset2();
categoryplot.setDataset(1, categorydataset);
categoryplot.mapDatasetToRangeAxis(1, 1);
CategoryAxis categoryaxis = categoryplot.getDomainAxis();
categoryaxis.setCategoryLabelPositions(CategoryLabelPositions.DOWN_45);
NumberAxis numberaxis = new NumberAxis("Secondary");
categoryplot.setRangeAxis(1, numberaxis);
LineAndShapeRenderer lineandshaperenderer = new LineAndShapeRenderer();
lineandshaperenderer.setToolTipGenerator(new StandardCategoryToolTipGenerator());
categoryplot.setRenderer(1, lineandshaperenderer);
categoryplot.setDatasetRenderingOrder(DatasetRenderingOrder.FORWARD);
LegendTitle legendtitle = new LegendTitle(categoryplot.getRenderer(0));
legendtitle.setMargin(new RectangleInsets(2D, 2D, 2D, 2D));
legendtitle.setBorder(new BlockBorder());
LegendTitle legendtitle1 = new LegendTitle(categoryplot.getRenderer(1));
legendtitle1.setMargin(new RectangleInsets(2D, 2D, 2D, 2D));
legendtitle1.setBorder(new BlockBorder());
BlockContainer blockcontainer = new BlockContainer(new BorderArrangement());
blockcontainer.add(legendtitle, RectangleEdge.LEFT);
blockcontainer.add(legendtitle1, RectangleEdge.RIGHT);
blockcontainer.add(new EmptyBlock(2000D, 0.0D));
CompositeTitle compositetitle = new CompositeTitle(blockcontainer);
compositetitle.setPosition(RectangleEdge.BOTTOM);
jfreechart.addSubtitle(compositetitle);
return jfreechart;
}

public static JPanel createDemoPanel()
{
JFreeChart jfreechart = createChart();
return new ChartPanel(jfreechart);
}
}

Selanjutnya yaitu tinggal menjalankannya melalui class main

package demo;

import org.jfree.ui.RefineryUtilities;
public class Main {
public static void main(String args[])
{
DualAxisDemo1 dualaxisdemo1 = new DualAxisDemo1("Dual Axis Demo 1");
dualaxisdemo1.pack();
RefineryUtilities.centerFrameOnScreen(dualaxisdemo1);
dualaxisdemo1.setVisible(true);
}
}

Hasilnya akan seperti ini :
