About products, components, and packages

Each SCO OpenServer product is arranged in the following units:


product
The unit of software that you buy. For example, SCO OpenServer Enterprise System and NeTraverse(TM) Merge(TM) are products. Each product has its own version number. A product is composed of one or more ``components'', ``packages'', or ``parcels''.

A ``patch-product'' is one or more patches distributed as a product.


component
The smallest unit of software that can stand alone. A component can constitute an entire product, or it can be one of many components in a product, but it cannot be split into smaller units for distribution. Each component has its own version number. A component is organized into a hierarchical tree of ``packages''.

A patch is applied to a component (rather than to a product or package).


package
The most basic unit of software that can be installed or removed. Each package consists either of files or of other packages. A package does not have its own version number; it inherits the version number of its parent component.

In addition to these units, a product might be subdivided into ``parcels''. In a parcel, related software is grouped for convenience. For example, a parcel might contain the documentation packages from several components, making it easier to install or remove all the documentation in a product. A parcel can contain one or more components, packages, or parcels from the product.
