- "Paper ratios, relational databases, and hypertext"
- ===================================================
-
- In presenting our hypertext concepts to the military, we picked up the
- following unclassified information:
-
- ┌───────────────────────────────────────────────────────────────────────────┐
- │ The amount of paper behind a battleship weighs more than the ship. │
- └───────────────────────────────────────────────────────────────────────────┘
-
- Now, don't laugh -- you're paying for all of it. In fact, this ratio of
- paper to objects is normal with any complex military system.
-
- For example, in the commercial aircraft industry, the standard rule of thumb
- is -- when the weight of the paper equals the estimated weight of the plane,
- it will fly. How does hypertext fit into this?
-
- Well, NASA spent last summer exploring the hypertext field in an effort to
- index all the information for building, launching, and maintaining the U.S.
- space station (to orbit in 1995). In effect, NASA has concluded that
- relational databases <FILE23 DATABASES> are unsuited for the task and that
- hypertext is the better choice for indexing future information (and not
- because hypertext weighs far less than the space station).
-
- Let me shift the subject for a minute.
-
- The EPA (Environmental Protection Agency) has been mandated by Congress to
- collect and organize all the information available on hazardous materials.
- The estimated annual amount of new EPA hazardous materials information is
- estimated at 200 megabytes a year. <FILE20 CD-ROMs) Yet, currently the
- EPA has no idea of how or when this Congressional mandate may be
- accomplished.
-
- Relational databases are unsuited for these purposes because of the following
- problems:
-
- ┌───────────────────────────────────────────────────────────────────────────┐
- │ Need to know the language of the subject area to access information │
- │ Need to know the synonyms to insure completeness of searches │
- │ Need to know set theory to conduct effective searches │
- │ System does not display information that almost matches search criteria │
- │ System does not communicate the structure of information in the system │
- └───────────────────────────────────────────────────────────────────────────┘
-
- In contrast, as hypertext indexing does not have these problems, it offers
- significant advantages in indexing large amounts of complex information.
-
- Hypertext can radically change the value <FILE65 KNOWLEDGE> and usefulness
- of the information mentioned in each of these collections. That's why both
- the military and NASA are interested in hypertext. <FILE43 EXAMPLES>
-
- As a summary, I'll say it again:
-
- ┌───────────────────────────────────────────────────────────────────────────┐
- │ -- the value of information lies in how it is organized! │
- └───────────────────────────────────────────────────────────────────────────┘
