Ask the vendor; the people that supply the "fuzzy object oriented database" software should know how to install it.

Then how did you deduce that it must be a fuzzy object-oriented query? Where did you find this code?

Ah..

Object-orientend means that you model the world according to objects (containing other objects) and their relations; relational means that you model the world into lists, with a relational to other lists. Fuzzy is something that is used more in logic than in storing data.

Data shouldn't be "fuzzy". Your client is either male or female, the data we store are facts. Imagine one of those facts becoming fuzzy.

My apologies for being rude; you seemed stubborn, but then again, you'll need something that convinces your collage. Feel free to ask more details if he keeps refusing the answer.

Comparison to RDBMS

In an RDBMS, it would be fairly common to see SQL statements like this:
  CREATE TABLE Customers  (
      Id          CHAR(12)    NOT NULL PRIMARY KEY,
      Surname     VARCHAR(32) NOT NULL,
      FirstName   VARCHAR(32) NOT NULL,
      DOB         DATE        NOT NULL
   );
   SELECT InitCap(Surname) || ', ' || InitCap(FirstName)
     FROM Customers
    WHERE Month(DOB) = Month(getdate())
      AND Day(DOB) = Day(getdate())
which some OO fans would describe as overly complex logic. Furthermore, most current SQL databases allow the creation of custom functions, which would allow the query to be expressed as:
   SELECT Formal(Id)
     FROM Customers
    WHERE Birthday(Id) = Today()
In an object-relational database, one might see something like this, where the data types and expressions such as BirthDay() are user-defined.
   CREATE TABLE Customers (
     Id           Cust_Id     NOT NULL  PRIMARY KEY,
     Name         PersonName  NOT NULL,
     DOB          DATE        NOT NULL
   );
   SELECT Formal( C.Name )
     FROM Customers C
    WHERE BirthDay ( C.DOB ) = TODAY;

That query won't work in Sql, nor any database-implementation that I know of. It's either a relational, or an object-oriented database.

"Object relational" sounds like theory to me.

Some OO fans should do their homework. Relational is a way of modelling, like object-oriented. One can't become "more like" the other, since it's two different ways of looking at stuff.

Right.

Creating functions doesn't make it "object-relational".

thanks for your help!
in which management i can have object-oriented database ?

i wanna to design object oriented database BUT i dont know in which platform or management i can do that ??????

thanks but is there any software that i can make(create) FOODB (Fuzzy Object Oriented DataBase) for SQL ?

I am seeking for software to create the DB first.

I am confuzed!

There is no such thing as a "fuzzy" object oriented database. The example you lnked to does not apply to an existing product.

Simply use SQL Server and you can create databases. Why does it need be "fuzzy"?

jojoba20 wrote:

..because you're looking for something that does not exist.

"Fuzzy object-relational"? What kind of data are you going to store that you're interested in that collection of buzzwords?

so how to use the code bellow ?
I wanna have Object Oriented DataBase (In an object-relational database, one might see something like this, where the data types and expressions such as BirthDay() are user-defined.)

this is example code for creating Table but give error in SQL Server Management 2008 !

CREATE TABLE Customers (
  Id           Cust_Id     NOT NULL  PRIMARY KEY,
  Name         PersonName  NOT NULL,
  DOB          DATE        NOT NULL
);



SELECT Formal( C.Name )
  FROM Customers C
 WHERE BirthDay ( C.DOB ) = TODAY;

The code from the example is not real code.

Then download one.

jojoba20 wrote:

Object-relational is nonsense.

jojoba20 wrote:

That's not example code, it's a made-up example. Sql Server is not an object oriented database and is not a fuzzy database. One talks to it using Sql, or using an ORM.

The example sql statement is a pack o' nonsense. I mean, convert C.DOB to a birthday? If you need a function, create one in SQL. There are dozens of manuals on how one creates a function and how to use that function in a query. Real examples, not converting X to X. Even the "formal" function is something that's standard SQL.

1) it's not a real life example
2) it's not real code
3) you don't need it

I'm convinced of 3 since you haven't named a single argument that says "need". I only read "want" from someone who cannot explain what it is he needs.

Have a read of this wiki page: Object Orientated database systems.[^]

as you can see the example you have been given come from here! the examples from this wiki page show that the SQL was and is written around database servers such as postgres etc.

The code like Eddy has said wont work on SQL Server!

The create table [^] statement is incorrect as you haven't specified the correct datatypes.

The Select statement wont work either, why? because you would need to create User definded functions[^] for Formal and BirthDay

for further reading Relational database systems (RDBMS)[^]

Based on your responses and the other responses to you...

The FIRST step is to define exactly what the above term means.

jojoba209-Oct-13 20:55

Thanks all!

SO Finally :
There isnt any management (or database server or Tools ) for creating Object-Oriented DataBases ?

Simon_Whale9-Oct-13 21:56

yes this Google search shows a wiki page object orientated databases[^].

There is a huge list there.

I have no experience with actually coding object orientated databases or even using them, I just know that they exist.

What I would suggest find out which database engine you are to use and then have a look at it's documentation.
