Applications and Package management systems
Application and Package management also known as software management is a collection of tools involved with application and software installation, removal, upgrades, package formats and repositories, such that the OS is maintained in a consistent state.
These managers deal with distributions, metadata, dependencies, archives and checksums. Package managers usually eliminate the need for manual installation of software.
On the other hand source code applications need to be compiled and built manually. These applications must be manually synchronized with the systems application database, where applicable.

Windows Application Manager:
- Windows Installer is used for installation, maintenance and removal of windows applications. Installation files and information are packaged into installation packages, COM files and MSI (MS Installer) files.
- Packages have a structure consisting of Products, features, components and Key Paths.
- Package Setup consists of several phases, these are: User interface, execution, and rollback.
- Windows Installer can advertise rather than install a package, install on demand, allow administrative installation, merge applications, interoperate with other Windows features, extract files and custom install.
- installer packages can be created using Visual studio and must interact with pertinent DLL’s and the registry.

Windows Package management
creating an application from source
To write your program, you'll need:
1) The Java SE Development Kit 8 (JDK 8)
You can download the Windows version now. (Make sure you download the JDK, not the JRE.) Consult the installation instructions.
2) A text editor (notepad will do)
3) Create a source file
/**
 * The HelloWorldApp class implements an application that
 * simply prints "Hello World!" to standard output.
 */
class HelloWorldApp {
    public static void main(String[] args) {
        System.out.println("Hello World!"); // Display the string.
    } }
4) Save file as HelloWorldApp.txt, with encoding as ANSI.
5) Compile the source file into a .class file
In a CMD window type: javac HelloWorldApp.java
6) Run compiled java application
In CMD window type: java -cp . HelloWorldApp

Linux Application Management
- for RHEL use yum, rpm or manual tools, to install, upgrade and remove applications.
The following is a list of the most commonly-used yum commands. For a complete list of available yum commands, refer to man yum.
- yum install <package name/s>
- yum update <package name/s>
- yum check-update
- yum remove <package name/s>
- yum provides <file name>
- yum search <keyword>
- yum localinstall <absolute path to package name/s>
By default, yum is configured through /etc/yum.conf
