SQL refers to Structured Query Language, a kind of language used to access, update and manipulate database. In SQL, ROLLBACK is a command that causes all data changes since the last START TRANSACTION or BEGIN to be discarded by the relational database management systems (RDBMS), so that the state of the data is "rolled back" to the way it was before those changes were made.
DataBlitz is a general purpose main memory database management system, developed by Lucent Bell Labs Research from 1993 to 1995. It replaced various home-grown database products used throughout Lucent beginning in 1997. It was originally named "Dali", and provided recovery and concurrency control features. Later, Dali was renamed as "DataBlitz".
CRUD is also relevant at the user interface level of most applications. For example, in address book software, the basic storage unit is an individual contact entry. As a bare minimum, the software must allow the user to: [6] Create, or add new entries; Read, retrieve, search, or view existing entries; Update, or edit existing entries
A database dump contains a record of the table structure and/or the data from a database and is usually in the form of a list of SQL statements ("SQL dump"). A database dump is most often used for backing up a database so that its contents can be restored in the event of data loss. Corrupted databases can often be recovered by analysis of the dump.
A data control language (DCL) is a syntax similar to a computer programming language used to control access to data stored in a database (authorization). In particular, it is a component of Structured Query Language (SQL). Data Control Language is one of the logical group in SQL Commands.
Access allows users to view and manipulate the SQL code if desired. Any Access table, including linked tables from different data sources, can be used in a query. Access also supports the creation of "pass-through queries". These snippets of SQL code can address external data sources through the use of ODBC connections on the local machine.

Part of the transaction log containing transactions completed by COMMIT or ROLLBACK. Because all relational databases contains, by definition, a transaction log (most of the time based on the [ARIES algorithm [Algorithms for Recovery and Isolation Exploiting Semantics]]), the log, which is a binary file, is divided into three parts, sequentially:
