Managing Your Data
When you work in the Datasets UI, there are different components that you can use to manage your data. The largest component is the Data panel, which is used to explore the spaces and sources in your data catalog, as shown in this image:
|1||By default, you have a homespace that you can further organize by creating a hierachy of folders, and you can create additional spaces.|
|2||A space is a directory in which views are saved. Spaces provide a way to group datasets by common themes such as a project, purpose, department, or geographic region.|
|3||A source is a data lake or external source (such as a relational database) that you can connect to Dremio.|
|4||The title indicates that the Samples data lake is open and lists the contents of the sample source. A source also consists of layers, so if you expand a data source, you will find datasets and data types within the datasets.|
|5||The datasets are listed from the Samples data lake. A dataset is a collection of data. The datasets stored in files can be in many different formats, and to run SQL queries against data in different formats, you can create tables and views. Tables are files or folders that are in your source, whereas virtual datasets are views derived from tables or other views.|
|6||Data types are the fields within the datasets.|
Adding Data Objects
By opening the SQL Runner, you can directly add data objects from the Data panel into the SQL editor.
To add the data object, locate the object in the Data panel that you would like to use within the query. Click the + button or drag and drop the data into the SQL editor.
Starring Data Objects
When viewing the Data panel in the SQL Runner, you can star spaces, sources, folders, and datasets, which adds the item to your Starred list for easier access. The Starred list can hold up to 25 entities at a time, and each starred item remains on the list unless you unstar it.
To star a data object:
- In the Data panel, locate the data object that you want to star. In this example, a dataset is being starred.
- Click the (Star) icon that appears next to the data object. The data object will appear on your Starred list.
To unstar an item, click the Star icon again.
Starring is different than pinning items. You can only pin spaces and sources in the Datasets UI.
