There are two main families of databases: Relational and NoSQL. Relational databases store information in an orderly, column, row, and table schema. They “relate” the tables together to present different views of the data. NoSQL databases are much less structured. This means they can store different data alongside each other – which makes things both easier to store but harder to query across. Relational Databases (RDBMS) Most users have at least heard of relational databases like:
MySQL / MariaDB PostgreSQL Microsoft SQL Server Oracle Relational databases operate on the concepts of tables, relations, indexes, SQL, CRUD operations, and joins.
Users can authenticate their SSH sessions using either a password or an ssh key. The instructions below describe how to create a key and use it for password-less authentication to your Linux instances.
About SSH Keys SSH keys are a pair of encrypted files that are meant to go together. One half of the pair is called the “private” key, and the other half is the “public” key. When users use the private key to connect to a server that is configured with the public key, the match can be verified and the user is signed in. Or, put it more simply, when data is encrypted using one half of the key, it can be decrypted using the other half.

Value and Project storage can be mapped to your Windows or Mac computer as a remote drive. If you are off Grounds you must be running a VPN, such as the UVA Anywhere or the More Secure VPN from ITS. We recommend the More Secure VPN if that is available to you.
Windows Open a File Explorer page. In Windows 10 first select This PC. This is not necessary for earlier versions of Windows. When you see the Computer tab, select that, then select Map Network Drive. When the dialog box appears, the default drive letter will be Z. You can change this to any other available letter if you wish.
