What does Application Packager do?
When a computer application is completed and distributed, the end user can start the program by clicking on one icon. During the development of this application, software engineers use a number of different sources that require highly technical processes to start and test the program. The task of Application Packager is to take over the various components that make up the program and make it so that the end user can easily install and run the application. They can take the form of software libraries, database files, compiled source code files and graphic components. Some of these files will be based in the program directory, but other sources such as database servers or system graphics motors must be installed as separate software on the end user .D as a separate system software into one folder. In the development process, programmers can call these resources from anywhere on their workstation, but the final products require a uniform configuration. By condense allHNY Files to a single directory, Application Packager ensures that all code in the program contains the correct directory paths to access these sources.
After Application Packger consolidates all the files that the program must run will prepare the directory for the end user. This includes replacing the default system icons for executable files with graphic artists icons designed specifically for the program and including documentation files to the directory. After these components are ready, the package must configure the installation program for the application.
The application package uses software specifically designed to create and automate upstairs processes. This includes:
- Specifications what software components must be present in the system to start the program
- load files necessary to add this software if the system is missing,
- to load addressescontaining all application files.
The last step is to test the package installation program on machines, which representatives of what customers will use to ensure that the process works.
Application packages require the background in the field of computer science and programming. They do not write the main parts of the source code of the program, but still have to understand the software development cycle and how to modify the source code. It is necessary for the source code to be precisely reflected in the final layout of the program directory file.
