Want this question answered?
See example code below. #include <iostream> class x { private: // Members. static int counter; int data; public: // Default constructor and destructor. x():data(++counter){printf("Object %d created!\n",data);} ~x(){printf("Object %d destroyed!\n",data);} // other members omitted for brevity... }; // Initialise static counter. int x::counter=0; int main() { // Instantiate an array of 10 objects. x arr[10]; // .. do some work with the array .. return( 0 ); // The array falls from scope, destroying the objects. } Example output: Object 1 created! Object 2 created! Object 3 created! Object 4 created! Object 5 created! Object 6 created! Object 7 created! Object 8 created! Object 9 created! Object 10 created! Object 10 destroyed! Object 9 destroyed! Object 8 destroyed! Object 7 destroyed! Object 6 destroyed! Object 5 destroyed! Object 4 destroyed! Object 3 destroyed! Object 2 destroyed! Object 1 destroyed!
Data is stored as objects and can be interpreted only using the methods specified by its class.
In C#, a reference type [of object] is an object created from a class, a value type is an object created from a struct. value type of objects are identical if their value/state are the same, while...
An object is created from a class, like a house made from a blueprint. The object will therefore be of the type of its class. For instance, a String object will be of type String, which is defined by the String class.
In java object is an instance of a class. Objects are created using the new keyword. When you use the new keyword along with a class name, an object of that class would get created. Ex: Ferrari obj = new Ferrari(); Here a new object of Ferrari gets created. A constructor of the class Ferrari would get invoked during the object creation.
Simple Object Database Access was created on 2002-04-16.
An object-oriented database (OODB) is a type of database that stores data in objects rather than in tables, making it easier to represent complex relationships and hierarchies in data. OODBs are designed to work well with object-oriented programming languages and frameworks.

No, object-oriented databases do not store data in tables like relational databases. Instead, they store data as objects that have attributes and methods associated with them. Objects in an object-oriented database can also have relationships with other objects, making it a more flexible way to store and access data.
The field in the database can store OLE (Object Linking and Embedding) objects, which are either linked to or embedded within the table. This allows users to insert objects like images, videos, or documents directly into the database field. OLE objects enable the database to manage and display these objects within the table.
In a Object Oriented Database, information is given in the form of objects as used in programming languages. "When database capabilities are combined with object programming language capabilities, the result is an object database management system (ODBMS). An ODBMS makes database objects appear as programming language objects in one or more object programming languages." (http://en.wikipedia.org/wiki/Object_database)"A relational database is a database that conforms to the relational model, and refers to a database's data and schema (the database's structure of how those data are arranged). Common usage of the term "Relational database management system" technically refers to the software used to create a relational database, but sometimes mistakenly refers to a relational database." (http://en.wikipedia.org/wiki/Relational_database)
Database table objects store data. Form objects used by applications provide a visually pleasing or sensible way of accessing or updating data contained in the database tables. This means that the form object is a display specification.
There are five steps to planning database files. These steps are collecting information, determining objects, modeling said objects, determining every object's information, and determining the relationships the objects have with one another.
An Object Oriented Relational Database Management System. An adapted form of the earlier RDBMS, in which it is made possible to work with Objects.
First of all, they may or may not differ. An object oriented database is a database you program by the use of small pieces, that, put together form an object. These objects can then be combined with other objects and/or be used separately. Actually, if you where to remove 'on leg' of the database that leg should be able to stand on its own. So goes the therory anyway. One relational database that has some benefits as an object oriented database is 4D. However, the stuff that one 'leg' can entirly support itself isn't actually true, however the objects are there and they do make a lot of sense. Am I making sense? --

In object-oriented databases, structured types refer to user-defined data types that can be created to model complex objects with multiple attributes. These structured types are defined by specifying the attributes and their related data types, allowing for the creation of custom objects with specific properties. Structured types in object-oriented databases enable more flexibility and organization in representing complex data structures.
