From a sample to your own project

[EasyQuery GitHub repositories](https://github.com/easyquery) contain several sample projects that demonstrate how to use EasyQuery library on different platforms, with differen frameworks and in different scenarios. The best way to start with EasyQuery is to choose the sample closest to your scenario and modify it according to your requirements (your DB, data model, environment, layout, styles, etc). So, in this section we are going to describe how to do it.

Working with several data models

All EasyQuery demos works with one data model (and one database which corresponds to that model). Here we are going to describe how to add a selector that switches between two data models on your view/page and then how to setup a custom "model loader" to handle GetModel requests propertly. To make it possible to switch between these two models we need some selector element on our page. The only problem here - is to switch the database connection accordingly the the switches between the models. Now when the user selects an item in our model selector element on the client-side - our server-side code automatically loads the selected model and connects to a proper database (when necessary)..
