In a real-world implementation, you may find it advantageous to utilize Windows authentication. However, it is also possible to authenticate via user names and passwords stored in the database. By default, SQL Server only allows authentication through operating system logins. The first will be to set up SQL Server to allow mixed-mode authentication.
Changing authentication settingsīefore we move on to setting up geodatabase users and roles, there are a couple of authentication settings we will change to make our lives a bit easier in this safe learning environment. If you STOP-ed your instance on purpose, or if your Remote Desktop Connection gets interrupted, you will need to re-START your instance via the EC2 Console.Īnd, if the IP address of the machine you're connecting with has changed since your last connection, remember that you may need to edit the RDP rule to allow connection from your new IP address. In the next section, you will be back working, via your Remote Desktop Connection, on your instance of the Amazon Machine Image (AMI) that holds our enterprise geodatabase, etc. A reminder, if and when you restart your instance of the AMI In this course, we're going to work with a DBO-owned geodatabase. If, on the other hand, those two roles are filled by different people, then having the SDE user own the geodatabase is probably more advisable. Generally speaking, if the SQL Server database administrator and the geodatabase administrator are the same person, then having the DBO user own the geodatabase is sensible. Esri's documentation includes a page that discusses the pros and cons of each. While the DBO user is the person who administers the database at the SQL Server level (e.g., creating new users and roles), the SDE user is the person who administers the database within ArcGIS (e.g., updating database statistics and compressing the database). Any member of the sysadmin fixed server role who uses a database is mapped to the DBO user and any object created by any member of the sysadmin fixed server role belongs to DBO automatically.Īn important consideration when implementing an enterprise geodatabase in SQL Server is who will be the owner of the geodatabase - the DBO user or the SDE user. Geodatabase ownershipĪll databases found on a SQL Server instance have a special user called DBO (short for database owner).

Among these is the sysadmin role which, as you might guess, has permissions that grant full control over the server. SQL Server also comes with a set of fixed server and database roles whose permissions cannot be changed. Database administrators can define their own desired roles and make permission changes for those roles as they see fit. A role provides a way to group similar users together so that permissions can be granted more easily. Related to logins and users is the concept of roles. This blog post provides further information. They answer the question, "What can this person do in the database?" As we'll see, logins must be mapped to database user accounts in order to work with database objects. Whereas logins are concerned with authentication, user accounts provide authorization to perform different tasks with a database. A login allows someone to authenticate with SQL Server and answers the question, "Who is connecting?" Access to an individual database (of which there could be several for a given SQL Server instance) is granted through users.
Access to SQL Server itself is granted through logins. Adding Users and Data to Your Geodatabase Logins and users in SQL Serverīefore diving into enterprise geodatabase concepts, it's important to understand some basics of working with SQL Server, the DBMS that we'll be using on our Amazon cloud instances.
