Transactional replication synchronizes databases in near real time. When pessimistic concurrency control is being used, SQL Server controls concurrent access by using locks.
When setting an Azure blob key in the connection properties dialog box when refreshing credentials, that setting will now be visually masked. When reading the page back, its checksum is computed again and matched with the stored version to ensure the page has not been damaged or tampered with in the meantime.
When a row is in the process of being updated, any other requests are not blocked unlike locking but are executed on the older version of the row.
Consequently, access to SQL Server is available over these protocols.
Exclusive lock grants the user exclusive access to the data—no other user can access the data as long as the lock is held. The buffer cache is managed by the Buffer Manager.
Microsoft also supports the Transport Layer Security protocol for securing communications between SQL Server clients and database servers.
SQL Server also provides the optimistic concurrency control mechanism, which is similar to the multiversion concurrency control used in other databases. They can be selectively provided access to.
However, doing that creates a new database session, different from the one in which the code is executing. Linked servers allow a single query to process operations performed on multiple servers.
Also because the code need not be sent from the client every time as it can be accessed by nameit reduces network traffic and somewhat improves performance. Ashton-Tate stepped away after that, but Microsoft and Sybase continued their partnership untilwhen Microsoft took over all development and marketing of SQL Server for its own operating systems.
If the other request is an update statement, it will result in two different versions of the rows—both of them will be stored by the database, identified by their respective transaction IDs.
SQLOS provides deadlock detection and resolution services for. Intended for use as an application component, it did not include GUI management tools.

Microsoft provides three versions of SQL Server for downloading: A connection to the database is required for all requests and processing. Prior to SP1, it was not enabled by default, and was not supported by Microsoft.
On Windows 8 and later versions of the client operating systems or Windows Server server and later versions of the server operating systems, TLS 1. The trained machine learning model can be stored inside a database and used for scoring.
The amount of memory available to SQL Server decides how many pages will be cached in memory. For further invocations of the same query, the cached plan is used. This is called query optimization and is performed by the query processor itself.
Improved performance when expanding Databases node when the server has autoclose databases. Always Encrypted, which lets user update encrypted data without having to decrypt it first; row-level securitywhich enables data access to be controlled at the row level in database tables; and dynamic data masking, which automatically hides elements of sensitive data from users without full access privileges.
Managed code is compiled to CLI assemblies and after being verified for type safetyregistered at the database. In some situations the heap structure has performance advantages over the clustered structure.
