## Content

* **Data source connectors:** Connects to CSV (comma-separated values), JSON (JavaScript Object Notation), OData (Open Data Protocol), SQLite, SQL Server, and PostgreSQL.
* **Query Builder:** Selects tables and columns, creates joins, defines filter conditions, and specifies table aliases without directly writing Structured Query Language (SQL) or Language Integrated Query (LINQ).
* **Data access modes:** Retrieves data through ADO.NET with DataTables or Entity Framework with scaffolding.
* **Query previews:** Displays query results in grid view and the generated query in code view. For Entity Framework connections, code view displays a LINQ query.
