One of the most remarkable features of DataMelt is its ability to handle large datasets with ease. With a built-in data structure called the ‘data frame,’ DataMelt can manage datasets with millions of rows and columns without taking a toll on memory or computing resources.
DataMelt is multi-language supported, enabling it to integrate with many programming languages including Python, Ruby, Groovy, and Jython. This makes it easy to use in a variety of environments and contexts, from scientific lab work to business intelligence applications.
Installation of Java and DataMelt on Linux
Before we can start using DataMelt, we need to install the
Java Runtime Environment (JRE) on our Linux machine. The JRE is essential for running Java-based software like DataMelt.
Java Runtime Environment
To download and install the JRE, we need to complete the following steps:
1. Open a terminal on your Linux machine and run the following command to download the open JDK version of the JRE:
sudo apt-get install openjdk-14-jre-headless
2. Once the download completes, we need to verify that the JRE is installed correctly by running the following command:
java -version
This will print out the version of Java installed on your machine, confirming that the installation was successful.
Wget
With the JRE installed, we can download and install DataMelt using a terminal command called ‘wget.’
Wget is a simple command used to download files from the internet. To download DataMelt, we have to complete the following steps:
1.
Open a terminal and navigate to the directory where you want to install DataMelt. 2.
Run the following command to download DataMelt:
wget http://jwork.org/dmelt/dmelt_downloads/repository/latest.zip
3. Once the download completes, we need to unzip the downloaded folder by running the following command:
unzip latest.zip
Access Application Files
With the DataMelt folder unzipped, we can access the application files. To execute DataMelt, we can use either the graphical user interface (GUI) or command-line interface.
To use the DataMelt GUI, navigate to the ‘bin’ directory, and run the following command:
./DataMelt
This will launch the GUI interface, allowing us to start using DataMelt. Alternatively, if you prefer a command-line interface, navigate to the ‘bin’ directory and run the following command:
./jython
This command will start a Jython shell, which you can use to run DataMelt commands.
