The first one, a My SQL database in which we will store the authors, and the second is a Postgre SQL database which will contain the authors books.Note that the properties for each data source are quite similar expect for the prefix part.
Creating a new database deployment in your m Lab account is a simple process after you’ve determined which plan you need.
Once you’ve subscribed to a plan, you can make changes to the deployment or delete it when you do not need it any longer.
Restoring a backup into a brand-new deployment using our “Create from backup” feature is a convenient way to change plans.
Alternatively, you can manually take a backup and then restore it to a new deployment on the desired plan.
Entity Framework v1/v4 provided no choice – the developer had to use the XML mapping approach.
With the release of Entity Framework 4.1, it became possible to develop applications using fluent mapping.In any case, the user must be ready for a situation when the standard capabilities of Visual Studio’s design-time model development are not convenient enough; either conditioned by their limited functionality or such capabilities are intended for use with SQL Server and can hardly be conveniently used when working with Oracle, for example.For that reason, a number of third-party solutions have been created: If it is necessary to develop an application that supports several different databases, there are several solutions in Entity Framework.In this tutorial, we will see how to make Spring Boot multiple databases configuration.Let’s consider the following case : We want to store authors and their books in two different databases.In this article, we shall briefly discuss some of the problems that the user may face in the process of developing an application for Entity Framework (EF), which is meant to interact with Oracle, My SQL, Postgre SQL or SQLite rather than Microsoft SQL Server.
