-# Data Access
+# Connection Strings
 
-ABP framework was designed as database agnostic, it can work any type of data source by the help of the [repository](Repositories.md) and [unit of work](Unit-Of-Work.md) abstractions. 
+ABP Framework is designed to be [modular](Module-Development-Basics.md), [microservice compatible](Microservice-Architecture.md) and [multi-tenancy](Multi-Tenancy.md) aware. Connection string management is also designed to support these scenarios;
 
-However, currently the following providers are implements:
+* Allows to set separate connection strings for every module, so every module can have its own physical database. Modules even might be configured to use different DBMSs.
+* Allows to set separate connection string and use a separate database per tenant (in a SaaS application).
 
-* [Entity Framework Core](Entity-Framework-Core.md) (works with [various DBMS and providers](https://docs.microsoft.com/en-us/ef/core/providers/?tabs=dotnet-core-cli).)
-* [MongoDB](MongoDB.md)
-* [Dapper](Dapper.md)
+It also supports hybrid scenarios;
 
-More providers might be added in the next releases.
+* Allows to group modules into databases (all modules into a single shared database, 2 modules to database A, 3 modules to database B, 1 module to database C and rest of the modules to database D... etc.)
+* Allows to group tenants into databases, just like the modules.
+* Allows to separate databases per tenant per module (which might be harder to maintain for you because of too many databases, but the ABP framework supports it).
+
+All the [pre-built application modules](Modules/Index.md) are designed to be compatible these scenarios.
+
+## Configure the Connection Strings
+
+See the following configuration:
+
+````json
+"ConnectionStrings": {
+  "Default": "Server=localhost;Database=MyMainDb;Trusted_Connection=True;",
+  "AbpIdentityServer": "Server=localhost;Database=MyIdsDb;Trusted_Connection=True;",
+  "AbpPermissionManagement": "Server=localhost;Database=MyPermissionDb;Trusted_Connection=True;"
+}
+````
+
+> ABP uses the `IConfiguration` service to get the application configuration. While the simplest way to write configuration into the `appsettings.json` file, it is not limited to this file. You can use environment variables, user secrets, Azure Key Vault... etc. See the [configuration](Configuration.md) document for more.
+
+This configuration defines three different connection strings:
+
+* `MyMainDb` (the `Default` connection string) is the main connection string of the application. If you don't specify a connection string for a module, it fallbacks to the `Default` connection string. The [application startup template](Startup-Templates/Application.md) is configured to use a single connection string, so all the modules uses a single shared database.
+* `MyIdsDb` is used by the [IdentityServer](Modules/IdentityServer.md) module.
+* `MyPermissionDb` is used by the [Permission Management](Modules/Permission-Management.md) module.
+
+[Pre-built application modules](Modules/Index.md) define constants for the connection string names. For example, the IdentityServer module defines a ` ConnectionStringName ` constant in the ` AbpIdentityServerDbProperties ` class (located in the ` Volo.Abp.IdentityServer ` namespace). Other modules similarly define constants, so you can investigate the connection string name.
+
+## Set the Connection String Name
+
+A module typically has a unique connection string name associated to its `DbContext` class using the `ConnectionStringName` attribute. Example:
+
+````csharp
+[ConnectionStringName("AbpIdentityServer")]
+public class IdentityServerDbContext
+    : AbpDbContext<IdentityServerDbContext>, IIdentityServerDbContext
+{
+}
+````
+
+For [Entity Framework Core](Entity-Framework-Core.md) and [MongoDB](MongoDB.md), write this to your `DbContext` class (and the interface if it has).
+
+> If you are developing a reusable, database provider independent module see also [the best practices guide](Best-Practices/Index.md).
+
+## Database Migrations for the Entity Framework Core
+
+Relational databases require to create the database and the database schema (tables, views... etc.) before using it.
+
+The startup template (with EF Core ORM) comes with a single database and a `.EntityFrameworkCore.DbMigrations` project that contains the migration files for that database. This project mainly defines a *YourProjectName*MigrationsDbContext that calls the `Configure...()` methods of the used modules, like `builder.ConfigurePermissionManagement()`.
+
+Once you want to separate a module's database, you typically will need to create a second migration path. The easiest way to create a copy of the `.EntityFrameworkCore.DbMigrations` project with the `DbContext` inside it, change its content to only call the `Configure...()` methods of the modules needs to be stored in the second database and re-create the initial migration. In this case, you also need to change the `.DbMigrator` application to be able to work with these second database too. In this way, you will have a separate migrations DbContext per database.
+
+## Multi-Tenancy
+
+See [the multi-tenancy document](Multi-Tenancy.md) to learn how to use separate databases for tenants.

+# Switch to EF Core MySQL Provider
+
+This document explains how to switch to the **MySQL** database provider for **[the application startup template](Startup-Templates/Application.md)** which comes with SQL Server provider pre-configured.
+
+## Replace the Volo.Abp.EntityFrameworkCore.SqlServer Package
+
+`.EntityFrameworkCore` project in the solution depends on the [Volo.Abp.EntityFrameworkCore.SqlServer](https://www.nuget.org/packages/Volo.Abp.EntityFrameworkCore.SqlServer) NuGet package. Remove this package and add the same version of the [Volo.Abp.EntityFrameworkCore.MySQL](https://www.nuget.org/packages/Volo.Abp.EntityFrameworkCore.MySQL) package.
+
+## Replace the Module Dependency
+
+Find ***YourProjectName*EntityFrameworkCoreModule** class inside the `.EntityFrameworkCore` project, remove `typeof(AbpEntityFrameworkCoreSqlServerModule)` from the `DependsOn` attribute, add `typeof(AbpEntityFrameworkCoreMySQLModule)` (also replace `using Volo.Abp.EntityFrameworkCore.SqlServer;` with `using Volo.Abp.EntityFrameworkCore.MySQL;`).
+
+## UseMySQL()
+
+Find `UseSqlServer()` calls in your solution, replace with `UseMySQL()`. Check the following files:
+
+* *YourProjectName*EntityFrameworkCoreModule.cs inside the `.EntityFrameworkCore` project.
+* *YourProjectName*MigrationsDbContextFactory.cs inside the `.EntityFrameworkCore.DbMigrations` project.
+
+> Depending on your solution structure, you may find more code files need to be changed.
+
+## Change the Connection Strings
+
+MySQL connection strings are different than SQL Server connection strings. So, check all `appsettings.json` files in your solution and replace the connection strings inside them. See the [connectionstrings.com]( https://www.connectionstrings.com/mysql/ ) for details of MySQL connection string options.
+
+You typically will change the `appsettings.json` inside the `.DbMigrator` and `.Web` projects, but it depends on your solution structure.
+
+## Change the Migrations DbContext
+
+MySQL DBMS has some slight differences than the SQL Server. Some module database mapping configuration (especially the field lengths) causes problems with MySQL. For example, some of the the [IdentityServer module](Modules/IdentityServer.md) tables has such problems and it provides an option to configure the fields based on your DBMS.
+
+The startup template contains a *YourProjectName*MigrationsDbContext which is responsible to maintain and migrate the database schema. This DbContext basically calls extension methods of the depended modules to configure their database tables.
+
+Open the *YourProjectName*MigrationsDbContext and change the `builder.ConfigureIdentityServer();` line as shown below:
+
+````csharp
+builder.ConfigureIdentityServer(options =>
+{
+    options.DatabaseProvider = EfCoreDatabaseProvider.MySql;
+});
+````
+
+Then `ConfigureIdentityServer()` method will set the field lengths to not exceed the MySQL limits. Refer to related module documentation if you have any problem while creating or executing the database migrations.
+
+## Re-Generate the Migrations
+
+The startup template uses [Entity Framework Core's Code First Migrations](https://docs.microsoft.com/en-us/ef/core/managing-schemas/migrations/). EF Core Migrations depend on the selected DBMS provider. So, changing the DBMS provider will cause the migration fails.
+
+* Delete the Migrations folder under the `.EntityFrameworkCore.DbMigrations` project and re-build the solution.
+* Run `Add-Migration "Initial"` on the Package Manager Console (select the `.DbMigrator`  (or `.Web`) project as the startup project in the Solution Explorer and select the `.EntityFrameworkCore.DbMigrations` project as the default project in the Package Manager Console).
+
+This will create a database migration with all database objects (tables) configured.
+
+Run the `.DbMigrator` project to create the database and seed the initial data.
