<div class="IPBDescription">Need help!</div> 1.) --DONE--

2.) Uses/Application of ROMS

3.) Definitions and examples of the following: Databases, tablets, fields, records, relationships, flatfiles


I already tried all the search engines I know but to no avail. If anyone has a book or has better searching skills than me, please help me out.

Thanks in advance to all who will lend a brother a helping hand.

[EDIT] I've already got the definitions for #3 from dictionary.com

    Have you tried <a href='http://www.google.com' target='_blank'>Google?</a> I copy pasted "History of RDBMS" in the search field and got about 29 000 results. Such topics as "Brief History of IT Management and the RDBMS", "ORACLE PL/SQL By Rizwan Alam Agenda Introduction History of RDBMS ...", "Brief History of Modern Database Technology & IT Management ..." etc.

    I don't think it's any harder with your other assignments.

    By ROM I assume you mean <b>R</b>ead <b>O</b>nly <b>M</b>emory

    This is a part on the motherboard that contains the BIOS (The really important bit) and cannot be changed or altered. (I'm sure someone like Talesin will correct me)

    Although asking for homework help is normally frowned apon on online forums, moreso by me <!--emo&;)--><img src='http://www.unknownworlds.com/forums/html/emoticons/wink.gif' border='0' style='vertical-align:middle' alt='wink.gif'><!--endemo--> I figure I might try my stab at #3, I havent done any of this for a little while, see how good my memory is. Its a bit iffy, but hopefully this might help a bit, and im sure google and some other places will clear it up <!--emo&;)--><img src='http://www.unknownworlds.com/forums/html/emoticons/wink.gif' border='0' style='vertical-align:middle' alt='wink.gif'><!--endemo-->

    Databases: A collection of data collected to form information. (Theres a difference between data and information, data is unsorted and kinda meaningless things, like a list of firstnames and last names and some phone numbers, information is an ordered, sorted and meaningful list, theres also metadata, which is data about data (see data dictionarys)). This data is stored in such a way as to provide ordered and 'simple' layout, ease of querying, into a Tables, fields, and records. Best example of a database would probably be a phonebook, a library bookkeeping system, or a student database thing at schools, that has a list of subjects etc etc
    tablets: Tablets.. ? You mean Tables? Otherwise this is way out of context.
    fields: In a database, defines a list of records. Examples like Firstname, Surname, Phonenumber etc etc in a Phonebook Database.
    records: The individual data in any given field. Say, under the FirstName field, you'll put Jon, under Surname you put Doe <!--emo&;)--><img src='http://www.unknownworlds.com/forums/html/emoticons/wink.gif' border='0' style='vertical-align:middle' alt='wink.gif'><!--endemo-->
    relationships: A connection point linking to similar databases(or tables) to reduce redundency. ie: A student database for a school, one for the students details, with a link from their classes to the ClassInformation database. Connected using a SecondaryKey. There are 3 relationships, one to one, one to many, and many to many. (Many to many is hard, you wont touch that I should think for a long while).
    flatfile: A Database that doesnt use any relationships.


    Also, <a href='http://www.jobsecurity.com/jobsecurity/courses/db101.htm' target='_blank'>this</a> website has some helpful stuff, try google for a bit <!--emo&:)--><img src='http://www.unknownworlds.com/forums/html/emoticons/smile.gif' border='0' style='vertical-align:middle' alt='smile.gif'><!--endemo-->
