FileMaker is probably the best known database application for the Mac. It has a feature set comparable to Microsoft Access, but with a strong focus on forms (layouts) as the primary way of accessing databases. Similar to Access, FileMaker stores your database logic and all the data in a single file.

The
RazorPagesMovieContext object handles the task of connecting to the database and mapping Movie objects to database records. The database context is registered with the Dependency Injection container in the ConfigureServices method in Startup.cs:
The ASP.NET Core Configuration system reads the
ConnectionString . For local development, it gets the connection string from the appsettings.json file.
The name value for the database (
Database={Database name} ) will be different for your generated code. Microsoft office 2019 mac os v16.27 torrent. The name value is arbitrary.
When the app is deployed to a test or production server, an environment variable can be used to set the connection string to a real database server. See Configuration for more information.
SQL Server Express LocalDB
LocalDB is a lightweight version of the SQL Server Express database engine that's targeted for program development. LocalDB starts on demand and runs in user mode, so there's no complex configuration. By default, LocalDB database creates
*.mdf files in the C:Users<user> directory.
Note the key icon next to
ID . By default, EF creates a property named ID for the primary key.
SQLite
The SQLite website states:
SQLite is a self-contained, high-reliability, embedded, full-featured, public-domain, SQL database engine. SQLite is the most used database engine in the world. https://supportgenerous.weebly.com/blog/can-microsoft-flight-simulator-run-on-mac.
There are many third party tools you can download to manage and view a SQLite database. The image below is from DB Browser for SQLite. If you have a favorite SQLite tool, leave a comment on what you like about it.
Note
For this tutorial you use the Entity Framework Core migrations feature where possible. Migrations updates the database schema to match changes in the data model. However, migrations can only do the kinds of changes that the EF Core provider supports, and the SQLite provider's capabilities are limited. For example, adding a column is supported, but removing or changing a column is not supported. If a migration is created to remove or change a column, the
ef migrations add command succeeds but the ef database update command fails. Due to these limitations, this tutorial doesn't use migrations for SQLite schema changes. Instead, when the schema changes, you drop and re-create the database.
The workaround for the SQLite limitations is to manually write migrations code to perform a table rebuild when something in the table changes. A table rebuild involves:
For more information, see the following resources:
Seed the database
Create a new class named
SeedData in the Models folder with the following code:
If there are any movies in the DB, the seed initializer returns and no movies are added.
Add the seed initializer
In Program.cs, modify the
Main method to do the following:
The following code shows the updated Program.cs file.
The following exception occurs when
Update-Database has not been run:
SqlException: Cannot open database 'RazorPagesMovieContext-' requested by the login. The login failed. Login failed for user 'user name'.
Test the app
Delete all the records in the DB (So the seed method will run). Stop and start the app to seed the database.
The app shows the seeded data.
The next tutorial will improve the presentation of the data.
