Realm is a mobile database that provides a simple object-oriented API for storing and managing mobile app data. It allows querying data using LINQ-like queries and synchronizing data across devices. Realm supports Android, iOS, Windows and server-side access to data and provides high performance for mobile apps. The presenter demonstrates Realm's capabilities and encourages the audience to visit Realm's website for more information.

20. DEMO? ☺

26. • Data is not persisted
• Only 10 MB cache
• OMG NOSQL

28. • Microsoft
• AZURE
• SQLite + strange security

32. What is server-side data access?

34. SELECT * FROM [Messages] WHERE
[UserId] = 'Vasya' AND [Date] = '2017-05-20'
var database = FindFile("VasyaPuprkin.realm");
var messages = database.Messages.Where(x => x.Date
== "2017-05-20");

35. SELECT * FROM [Messages] WHERE
[Date] = '2017-05-20'
foreach (var user in users)
{
var database = FindFile(user + ".realm");
var messages = database.Messages
.Where(x =>x.Date == "2017-05-20");
}
