HTML5 Builder Mobile Development & Deployment.A simple mobile shopping list with HTML5 Builder.Data Viewer Read, edit and create data from your databases. Query Designer Design queries to be executed against your databases in a visual way. The following tools will help you work with databases:Дata Explorer It lets you browse your databases, generate components already set up to work with them, and more.

That way, you can later include that module from any other page, avoiding duplicated work by reusing the same components.ДЄfter you follow the component-based approach to configure a Database component and link one or more DataSet components to it, you can directly access the data from the latter using code.ДЇor information on how to interact with these components from code, see DataSet Components. You can place any Database, DataSet and Datasource components in a server data module. Your component will now work with the data from the database.

Add a data-aware component and set its DataSource property to the Name property of the DataSource component.

Add a Datasource component to your application, and set it up to work with the DataSet component.

So once you have a working DataSet component, you need to: That is why all data-aware components have a DataSource property you have to point to that DataSource component. But in order to make that association, you need a connector, a bridge between the DataSet component and the data-aware component: a Datasource component.

Those components are called data-aware components. There are some components that can be associated with a DataSet component so the former renders the data in the second. There are several components you can use to retrieve data from a Database, those called DataSet components, components that extend the DataSet class.ДataSet components perform a query on the Database component and store the resulting data. Once the connection is ready, you need to retrieve some data from it.

You can either add a Database component to your application from the Tool Palette and then configure it, or you can drop a database onto the Designer directly from the Data Explorer, which will generate a Database component already configured. In HTML5 Builder, the component that takes care of that connection is Database. To work with a database, you first need to get a working connection to one. Note: You can use the Data Explorer instead to speed up the whole process. Follow the steps below to configure a connection: You can combine data-access components and data controls to develop web applications that read or write on databases, and can perform advanced operations with them.

1.3 Associate a Component to the DataSet.
