Data Model
/fundamentals/data-modelIn short (and by its name), data model - is a model (representation) of some data stored in your database. It solves two major problems: Presents the data to the end user in a more friendly and familiar way. Contains some meta information that helps EasyQuery components to build query statements in SQL or other query languages. Any data model contains the following main sections:
Entities page
/data-model-editor/entities-pageThis page describes entities participating in the data model and their attributes.
Value Editors
/data-model-editor/value-editorsHere you can find the full list of editors and choose any you need in your work with Data Model:
Operator class
/api-reference-4x/korzh-easyquery-namespace/operator-classRepresents a logical expression or predicate, like comparisions or LIKE predicate.
Operator class
/api-reference-5x/korzh-easyquery-namespace/operator-classRepresents a logical expression or "predicate". For example: "less than", "is equal to", "starts with".

Working with several data models
/tutorials/several-data-modelsAll 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)..
Possible ways of data model creation and loading
/tutorials/data-model-creation-loadingEasyQuery components need a [data model](/$aid/03bc06b0-83ec-4040-97ef-a50ca004177f) (a user-friendly representation of your DB) for their work. There are several different ways to create the model and load it on your project's startup. This article will describe all of them in detail.
