The SqlCommand object can be used to support disconnected data management scenarios, but in this lesson, we will only use the SqlCommand object alone. Fast Object Database for Java - with JPA/JDO support. Object-oriented databases treat each entity as a distinct object.

The DataReader object in C# is used to hold all the data returned by the database. There is a unique object identifier OID to identify the object. A connection string looks like this. Now, if you want to search for this in each database, you will have to iterate through the databases. An object database management system (ODBMS, also referred to as object-oriented database management system or OODBMS), is a database management system (DBMS) that supports the modelling and creation of data as objects. I need something that is cross-language, but also that supports an object model. An object-oriented database is a database that subscribes to a model with information represented by objects.

The following example will demonstrate how a web page can fetch information from a database with AJAX: Example • Complete object and relational database management system • Built in web gateway with large scale concurrency. The data in relational database are mapped to object models and stored in object data database. The state is represented by the values of the object's attributes, and the behavior is defined by the methods acting on the state of the object.

You only have to change the connection string and a few queries. Object-oriented databases are a niche offering in the relational database management system (RDBMS) field and are not as successful or well-known as mainstream database engines. An object-oriented database management system (OODBMS), sometimes shortened to ODBMS for object database management system, is a database management system that supports the modelling and creation of data as objects.This includes some kind of support for classes of objects and the inheritance of class properties and methods by subclasses and their objects.
