Description

Entity Framework (EF) Core is a versatile, lightweight, and open-source version of the widely used Entity Framework data access technology that operates across different platforms. It empowers .NET developers to interact with databases through .NET objects, significantly reducing the amount of data-access code that would typically need to be written. In EF Core, data interaction occurs through a model, which consists of entity classes and a context object that acts as a connection to the database. This context object facilitates both querying and data manipulation. Developers can generate a model directly from an existing database or manually create one to correspond with the database schema. After establishing a model, EF migrations can be employed to build a database from it, allowing for the database to evolve in tandem with any changes made to the model. Furthermore, instances of entity classes can be retrieved from the database using Language Integrated Query (LINQ), and operations such as creating, deleting, and modifying records in the database are accomplished through these instances, thus streamlining the data management process. Overall, EF Core simplifies database interactions and enhances the efficiency of data-driven applications.

Description

Objectivity/DB (or Object Database Management System) is a distributed, highly scalable, high-performance, and highly scalable Object Database (ODBMS). It excels at complex data handling, including many types of connections between objects as well as many variants. Objectivity/DB can also be used as a graph database that is highly scalable and high-performance. Its DO query language allows for standard data retrieval queries and high-performance path-based navigational inquiries. Objectivity/DB is a distributed data base that presents a single logical view of its managed data. Data can be hosted on one machine or distributed over up to 65,000 machines. Machines can be connected to one another. Objectivity/DB can be used on 32- or 64-bit processors that run Windows, Linux, and Mac OS X. APIs are C++, C# Java, Python, and Java. All platforms and languages are interoperable. A C++ program on Linux can store objects and a Java program on Mac OS X can read them.
