  5. PLA6Logic Programming with Prolog Due Friday, April 25, 11:59pm (30 pts) • Relational database consisting of four tables of information on • suppliers (S), parts (P), projects (J), project (SPJ) • Supplier numbers (S#), part numbers (P#), & project numbers (J#), are unique in tables S, P, & J • http://wiki.c2.com/?SupplierPartsProjectsDatabase • Represent DB as Prolog Facts • Define Relevant Prolog Rules • Write Prolog Queries

  6. Databases Tables

  7. Prolog Facts and Rules – pla6pll supp(s# sname status city) part(p# pname color weight city) proj(j#jname city) sppj(s# p# j#qty) suppliesparts(S,P,N,T,C,J,A):-supp(S,N,T,C),sppj(S,P,J,A). usedbyproject(P,N,C,A,L,S,J,D):-part(P,N,C,A,L),sppj(S,P,J,D). usesparts(J,A,B,P,N,S,J,X,G,H):- proj(J,A,B), sppj(S,P,J,X), part(P,N,G,H). notinlocation(S,N,T,C,J,A,B):-supp(S,N,T,C),proj(J,A,B),not(C=B).

  8. Prolog Queries • When given a pair of projects, find all suppliers who supply both projects. Return the entire entry (i.e., S#, Sname, Status, City) for the supplier. • When given a city, find all parts supplied to any project in that city. Once again, return the entire entry for the part. Find all parts supplied to any project by a supplier in the same city. In this case, results are organized by all parts for every city in the database. • Find all projects supplied by at least one supplier not in the same city. • Find all suppliers that supply at least one part supplied by at least one supplier who supplies at least one red part. • Find all pairs of city values such that a supplier in the first city supplies a project in the second city. • Find all triples of city, part#, city, such that a supplier in the first city supplies the specified part to a project in the second city, and the two city values are different. • When given a supplier, find all projects supplied entirely by that supplier.

  9. PLA5 Word Index Using Strings in Ada April 1, 11:59pm (30 pts) • Extend PLA4v3 with a word index that tracks the line(s) within the input file where each word occurs. There may be multiple occurrences of the word in a file. Current output of PLA3v3 is: Goodbye 4 Hello 1 World 1 • You are to update the output to: Goodbye: in lines 1-2-5-6 wc=4 Hello: in lines 3 wc=1 World: in lines 3 wc=1 • Assume: Each word at least one character and start with a letter. If a word has 2 or more characters, then the second and successive characters can be letters, digits, the underscore, or the hyphen

With ada.integer_text_io; use ada.integer_text_io; With ada.text_io; use ada.text_io; Procedure new_u_words_minis type Word is record s: String(1 .. 120); -- The string. Assume 120 characters or less wlen: Natural; -- Length of the word Count:Natural:=0; -- Total number of occurrences of this word LineNo: Natural :=0; -- Word found on LineNo end record; type Word_Arrayis array(1 .. 1000) of Word; type Word_Listis record words: Word_Array; -- The unique words Num_Words:Natural:=0; -- How many unique words seen so far curr_line: Natural := 1; -- Current Line end record;

  11. new_u_words_min.adb procedure get_words(wl: out Word_List) is begin wl.num_words := 0; -- only to get rid of a warning while not End_of_Fileloop declare s: String := Get_Line; found: Boolean := false; begin for iin 1 .. wl.num_wordsloop if s = wl.words(i).s(1 .. wl.words(i).wlen) then wl.words(i).count := wl.words(i).count + 1; found := true; end if; exit when found; end loop;

  12. new_u_words_min.adb if not found then -- Add word to list wl.num_words := wl.num_words + 1; wl.words(wl.num_words).s(1 .. s'last) := s; wl.words(wl.num_words).wlen := s'length; Wl.Words(Wl.Num_Words).Count := 1; Wl.Words(Wl.Num_Words).LineNo:= wl.curr_line; -- set LineNo of word wl.curr_line := wl.curr_line + 1; -- one word per line so increase curr_line end if; end; -- declare end loop; end get_words;

  13. new_u_words_min.adb procedure put_words(wl: Word_List) is begin for iin 1 .. wl.num_wordsloop put(wl.words(i).LineNo); put(wl.words(i).count); put(" " & wl.words(i).s(1 .. wl.words(i).wlen)); new_line; end loop; end put_words; the_words: Word_List; begin get_words(the_words); put_words(the_words); end new_u_words_min;

  14. Output of Revised Program • First number is last line it appeared • Second number occurence

  15. Suggested Solution Approach • Build an dedicated output string for the word, its occurrences in lines, and final word count. • Programmatically, for the word “Goodbye” the string would be built in the following steps: Goodbye in lines: -- create when the word is first found Goodbye in lines: 1 -- append “ 1” when the word is first found Goodbye in lines: 1-2 -- append “-2” when the word is found in line 2 Goodbye in lines: 1-2-5 -- append “-5” when the word is found in line 5 Goodbye in lines: 1-2-5-6 -- append “6” when the word is found in line 7 Goodbye in lines: 1-2-5-6-6 -- append “6” when the word is found again in line 7 -- Etc… • Built as the words are recognized on each line • After EOF reached for all words, you print out the new dedicated output string for the word and append “wc=” and then print out the word count 5 as an integer • You can also convert the word count to string and append

  16. PLA4 Due 3/14/19 11:59pm To HuskyCT • Modify an existing word frequency function Ada program (u_words_min.adb) or (u_words_tight.adb) that implements WFF by assuming that there is one word in every line of the input. • Both of the adb files assume a word of 20 characters as a string – in the posted web copies of the two files, this has been increased to 120 which has the result of reading the entire line and treating the entire line as one large word which can include spaces. • So, when the program is compiled and run, the input generates the following output:

  17. PLA4 Due 3/14/19 11:59pm To HuskyCT • This programming project is an exercise in learning a new language by having to modify and extend someone else’s code. The specific extensions are as follows for three separate versions: • V1: Change the original program to alphabetically sort the outputted list of words – first executable. • V2: + V1 Change the logic so that the words within each line are identified – this would then result in a full word frequency functionality and if the sort has been implemented, it will now sort the entire list – second executable. • V3: +V1+V2 Change the program so that the data is read from input.txt and written to output.tex – third executable. • Use AdaGIDE https://sourceforge.net/projects/adagide/and upload your .adb files to HuskyCT. If you use a GNAT compiler, please make sure it compiles/runs in the IDE.

  18. Three Versions • (10 pts) V1Change the original program to alphabetically sort the outputted list of words – first executable. • (10 pts) V2 + V1 Change the logic so that the words within each line are identified – this would then result in a full word frequency functionality and if the sort has been implemented, it will now sort the entire list – second executable. • (10 pts) V3+V1+V2 Change the program so that the data is read from input.txt and written to output.tex – third executable.
