8.1.Frequently Asked Questions

¶ 8.1.1. Is X-Server offered as a hosted service?

Yes. X-Server is a cloud-hosted database-as-a-service.

¶ 8.1.2. How does a collection differ from a table?

Instead of tables, a X-Server database stores its data in collections. A collection holds one or more JSON documents. Documents are analogous to records or rows in a relational database table. Each document has one or more fields; fields are similar to the columns in a relational database table.

¶ 8.1.3. How do I create a database and a collection?

If a database does not exist, X-Server creates the database when you first store data for that database.

If a collection does not exist, X-Server creates the collection when you first store data for that collection.

¶ 8.1.4. Does X-Server support SQL?

Not directly, no. However, X-Server does support a rich query language of its own. For examples on using MongoDB’s query language, see CRUD Interface Operations.
