Applications and Package management systems University of Texas Rio Grande Valley Systems Administration CSCI 6175.01 Fall 2016 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.

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.
