In this episode, Robert is joined by Phil Japikse for part 2 of a 5 part series on Entity Framework Core. Aimed at folks new to EF Core, Phil shows how to start with an existing SQL Server database, create entities/objects for each table and then how to perform basic CRUD operations on the data. Change Tracking is one of the most compelling reasons to use an object-relational-mapper (ORM) like EF Core. In this episode we discuss how the change tracker works, see it in action, as well as load data outside of the change tracker. Find the sample code here. Episode list: Part 1: Working with Existing Databases. We scaffold the DbContext and the Entities from the Northwind Database, discuss navigation properties and relationships.Part 2: Change Tracking (this episode). Part 3: Basic Queries (coming soon). This episodes querying data using EF Core. We discuss the basics of where clauses, retrieving single items or lists of items, as well as when queries actually execute.Part 4: Querying Related Data and Using Projections (coming soon). Querying related data is simple in EF Core, and In this episode we demonstrate creating joins in our LINQ queries with Include and ThenInclude. We also discuss how you use projections to shape the queried data into other objects, anonymous or strongly typed.Part 5: Putting the CUD into CRUD (coming soon). Wrapping up our starter series on EF Core, this episode covers adding, updating, and deleting data using EF Core.

Indexing and Querying are pivotal when building the search platform. This video explains how Azure cognitive search works and how developers can add their own input to it. The focus is on explaining how information processing in search engine is divided in to indexing and querying, important steps for both the processes, document processing, adding indexing time, creating inverted index, retrieving documents and writing the results.
