Global Environment Assignment Help

[vin3e]

Right guys,

I'm so sorry to keep asking you guys for help but I'm finding this little assignment quite confusing. The question asks: "Design a data model (and represent that as an XML DTD) which could describe a bibliographic and publisher database". I have chosen to come up with a library of Children's from ranging from Harry Potter to The Very Hungry Caterpillar but I do not know what the question is asking me to do.

I have already written an XML file with all data surrounding 20 books e.g. shown below.

<?xml version="1.0"?>

<?xml-stylesheet type="text/css" href="libcss.css"?>

<!DOCTYPE library SYSTEM "Librarylist.dtd">

<library>

<author>

<firstname>J.K.</firstname>

<lastname>Rowling</lastname>

</author>

<book>

<id>JK01</id>

<book_title>Harry Potter and The Philosopher's Stone</book_title>

<publisher>Bloomsbury</publisher>

<year>1997</year>

<book_no>Book 1</book_no>

</book>

</library>

]And then i've written a very basic DTD which is:

<!ELEMENT author (firstname?, lastname)>

<!ELEMENT firstname (#PCDATA)>

<!ELEMENT lastname (#PCDATA)>

<!ELEMENT book (author+, book_title, publisher, book_no, year)>

<!ELEMENT book_title (#PCDATA)>

<!ELEMENT publisher (#PCDATA)>

<!ELEMENT book_no (#PCDATA)>

<!ELEMENT year (#PCDATA)>

<!ELEMENT image (#PCDATA)>

From here on, I do not know if I am heading in the right direction of the question. "Does my XML DTD represent my chose data model?".

If anyone with any sort of help please help a stressed individual out, it would be very appreciative.

Sigh at lack of responses :(

Maybe because most have no idea what exactly you're asking? I for one don't... :(

QQ

Basically, I dont understand the question and thought I would ask people to interpret it in their own words to make it understandable for me.

I don't know if they question is asking me to create more than just an XML and DTD because the amount of work seems very little, especially for a 40% weighted assignment :(

I hope thats more easier to understand.

I suggest you read the following here and here (navigate to next pages)

After reading I would suggest the following changes

either go with

<library>
 <authors>
  <author><id>something</id><firstname></firstname>...</author>
  <author>...</author>
 </authors>
 <books>
   <book><authorid>something</authorid><title></title>...</book>
   <book><authorid></authorid>...</book>
 <books>
<library>

- Or -

<library>
 <author>
  <firstname></firstname>
  <book>...</book>
  <book>...</book>
  <book>...</book>
 </author>
 <author>
 </author>
<library>

Hope this helps

use this page with IE to validate your findings

on a side note you probably want to ask such questions in more specialized development forums in the future
