About the Books
Moderne Datenzugriffslösungen mit Entity Framework 6
Datenbankprogrammierung mit .NET und C#
Um die Handhabung von relationalen Datenbanken in objektorientierten Systemen natürlicher zu gestalten, setzt die Software-Industrie seit Jahren auf O/R-Mapper. O steht dabei für objektorientiert und R für relational. Diese Werkzeuge bilden demnach Konzepte aus der objektorientierten Welt, wie Klassen, Attribute oder Beziehungen zwischen Klassen auf entsprechende Konstrukte der relationalen Welt, wie zum Beispiel Tabellen, Spalten und Fremdschlüssel, ab. Der Entwickler kann somit in der objektorientierten Welt verbleiben und den O/R-Mapper anweisen, bestimmte Objekte, welche in Form von Datensätzen in den Tabellen der relationalen Datenbank vorliegen, zu laden bzw. zu speichern. Wenig interessante und fehleranfällige Aufgaben, wie das manuelle Erstellen von INSERT-, UPDATE- oder DELETE-Anweisungen übernimmt hierbei auch der O/R-Mapper, was zu einer weiteren Entlastung des Entwicklers führt. Beim Entity Framework handelt es sich um einen solchen O/R-Mapper, der mittlerweile ein fixer Bestandteil von .NET ist. Dieses Buch zeigt, wie damit Datenbanken auf moderne und zeitsparende Art und Weise angesprochen werden können. Das Buch richtet sich an Softwareentwickler, die bereits grundlegende Erfahrung mit .NET, insbesondere C#, ADO.NET und LINQ, sowie mit relationalen Datenbanken gesammelt haben und nun Entity Framework 6.x zur Erstellung von Datenzugriffscode einsetzen wollen.
Moderne Datenzugriffslösungen mit Entity Framework Core 2.1/2.2
Datenbankprogrammierung mit C# in .NET/.NET Core/Xamarin
Entity Framework Core ist der neue Objekt-Relationale Mapper und die aktuelle Datenzugriffstechnik von Microsoft für .NET-, .NET Core-, UWP- und Xamarin-Anwendungen. Das Buch enthält alle wichtigen Szenarien des Datenbankzugriffs auf Microsoft SQL Server, SQLite und Oracle: Konzepte und Installation von Entity Framework Core, Reverse Engineering bestehender Datenbanken und Forward Engineering inkl. Schemamigrationen, Microsoft SQL Server und SQLite, Daten lesen und ändern mit LINQ, Dynamic LINQ, API, SQL, Views, Stored Procedures und Table Value Functions, Objektbeziehungen und Ladestrategien, Change Tracking, Protokollierung, Datenänderungskonflikte, Transaktionen, Leistungsoptimierung, asynchrone Programmierung sowie die Zusatzprodukte Entity Framework Core Power Tools, LINQPad, Entity Developer, Entity Framework Profiler, EFPlus und AutoMapper. Auch der Praxiseinsatz von Entity Framework Core in der Softwarearchitektur wird diskutiert und anhand von Fallbeispielen in Windows Universal Apps, Xamarin und ASP.NET Core implementiert. Zudem enthält das Buch zahlreiche Tipps und Tricks.
Das Buch richtet sich an Softwareentwickler, die bereits grundlegende Erfahrung mit .NET und C# sowie mit relationalen Datenbanken gesammelt haben und nun Entity Framework Core zur Erstellung von performantem und plattformunabhängigem Datenzugriffscode in .NET, .NET Core, UWP Apps oder Xamarin einsetzen wollen. Vorkenntnisse in Vorgängerprodukten wie ADO.NET und dem klassischen ADO.NET Entity Framework oder anderen OR-Mappern sind zum Verständnis des Buchs nicht notwendig.
