# Osmos Datasets
## Overview
This page outlines the initial process for creating a new Osmos Dataset.
## Creating an Osmos Dataset
Step 1: Click the Datasets icon and select **Create Dataset.**
Step 2: In the New Dataset Window, enter the name of your **Dataset.**
Step 3: Hit **Save.**
## Adding a Table to your Osmos Dataset
Step 1: Click the Dataset icon, and select your newly created **Osmos Dataset**.
Step 2: Select **Add New Table.**
Step 3: Enter the **Table Name.**
Step 4: Enter the **Schema.**
Design the output schema via two options, either import the schema or build it within Osmos.
#### Option 1: Schema Import
Upload or drag & drop the schema file.
{% hint style="info" %}
Import a file with the headers along with one row of sample data. This data is used ***only*** in schema creation.
{% endhint %}
#### **Option 2: Building the Schema for the Destination Connector**
Use the schema designer to build the output schema for your table.
| Parameter | Description |
| --------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Field Name | Provide a field name for the output fields. These names will be used as the column headers or field names in the output file you are writing to. |
| Type | Define the type of each field. The field types will be used to enforce rules when you send data to this Connector. |
| Required | Check this box if the field is nullable. If the field is not nullable, you will be required to provide values for this field when sending data to this Connector. |
| Actions | Deletes the field. |
| Add Field | Adds another field to the schema. |
| Upload Schema | Upload schema or drag & drop header fields |
| Add Foreign Key | Add a foreign key column to be used in a lookup & join criteria when the data from a related table is combined |
A Primary key can be associated with this table. The key field must be required and unique.
{% hint style="info" %}
See [Key Fields](https://docs.osmos.io/datasets/getting-started/creating-primary-and-foreign-keys) for more detail
{% endhint %}
Select Save Table.
## Dataset Actions
You can take four actions in a Dataset.
1. Create Table
2. Access QueryBuilder
3. Clone a Dataset
4. Edit a Dataset
Here is a drill down on the Dataset options:
### Create Table
[See above](#creating-an-osmos-dataset)
### Query your Dataset
Drill directly into the Query Builder to build your table filters, joins, and aggregations.
Step 1: Click the cylinder icon from your **Osmos Dataset**
For more guidance on [the Query Builder.](https://docs.osmos.io/datasets/datasets-query-builder)
### Cloning your Osmos Dataset
Cloning will duplicate a Dataset. Note, that this process will move the existing tables but will not clone the data in each table.
Step 1: Click the clone icon from your **Osmos Dataset**.
Step 2: Select the **Project.**
Step 3: Enter the new **Dataset Name.**
Step 4: Click on **Clone.**
