LARGE PROGRAMS
Modules or objects provide both functionality and services. Modules can embody concepts such as information hiding and can contain parallel threads of execution. Modules are usually compiled separately and then linked to create a program. Modules written in different languages can be linked.
HYPERTEXT
Parts of a document can reside on different sites or in different file spaces, but in general hypertext has no concept equivalent to encapsulation. Limiting user domains can provide some scope control. Developers can create pages separately and develop them using different tools. Several forms of linkage exist, although all are based on interrelations.
COMMENT
Similarities are greater than initially expected, but offer little constructive help.
Characteristic -- Component reuse
LARGE PROGRAMS
Different programs can reuse modules and objects through static or dynamic linking. Mechanisms such as CORBA (Common Object Request Broker Architecture) extend reuse possibilities.
HYPERTEXT
Several documents can incorporate the same Web page, either via copies (or Unix links) or by HTML links. Such links also reuse documents on different sites.
COMMENT
Reusable components provide major motivation for better version control.
Characteristic -- Testing
LARGE PROGRAMS
Modules must be tested for their individual properties as well as their contribution to the integrated whole.
HYPERTEXT
Page development and maintenance practices do not currently account for either individual or integrated properties.
COMMENT
Experience is potentially transfer-able.
