3.0NON-FUNCTIONAL

REQUIREMENTS

The Online Journal will be on a server with

high speed Internet capability.

The physical machine to be used will be

determined by the Historical Society.

The software developed here assumes the

use of a tool such as Tomcat for connection

between the Web pages and the database.

The speed of the Reader’s connection will

depend on the hardware used rather than

characteristics of this system.

The Article Manager will run on the editor’s

PC and will contain an Access database.

Access is already installed on this computer

and is a Windows operating system.

4.O ASSUMPTIONS

The Reader is expected to be Internet literate and

be able to use a search engine.

The Author and Reviewer are expected to be

Internet literate and to be able to use email with

attachments.

The Editor is expected to be Windows literate and

to be able to use button, pull-down menus, and

similar tools.

SEARCH ARTICLE

PROPOSITIONAL CALCULUS

Search_by_author : the search is by Authorsystem_creates : the system creates present_alphabetical : presents an alphabetical list of all authors in the database.

Search_by_author => system_creates^present_alphabetical

Reader_selects_by_category : the Reader selects to search by category

system_creates : the system creates

present_list_categories : presents a list of all categories in the database

Reader_search_keyword : the Reader selects to search by keyword

system_presents_dialog_box_enter_keyword : the system presents a dialog box to

enter the keyword

phrase : phrase

Reader_search_keyword => system_presents_dialog_box_enter_keyword V

phrase

PREDICATE CALCULUS

Search(author) : the search is by Author

system(creates) : the system creates

alphabetical(present,authors) :presents an alphabetical list of all authors in the database

Search(author) => system(creates)^ alphabetical(present,authors)

Search(reader_selects,category): the Reader selects to search by

category

creates(system): the system creates

categories(present,database):presents a list of all categories in the

database.

Search(reader_selects,category)=>creates(system)^categories(present,database)

COMMUNICATE

PROPOSITIONAL CALCULUS

User_email_directly : the user prefers to use his or her own email directly

6.0 COMMENTS ABOUT THE TRANSLATION PROCESS

FROM NATURAL LANGUAGES STATEMENTS TO

MATHEMATICAL STATEMENTS.

ambiguity: Natural languages are full of ambiguity, which

people deal with by using contextual clues and other

information. Mathematical statements are designed to be

unambiguous, which means that any statement has

exactly one meaning, regardless of context.

redundancy:To make up for ambiguity and reduce

misunderstandings, natural languages are often

redundant. Mathematical statements are more concise.

Statement :The meaning of a Mathematical statements is unambiguous and literal, and can be understood entirely by analysis of the tokens and structure.

literalness:Natural languages are full of idiom and metaphor. Formal languages mean exactly what they say.People who grow up speaking a natural language (everyone) often have a hard time adjusting to formal languages. In some ways the difference between formal and natural language is like the difference between poetry and prose, but more so .
