To commit a change in git on the command line, assuming git is installed, the following command is run: [1] git commit -m 'commit message' This is also assuming that the files within the current directory have been staged as such: [2] git add . The above command adds all of the files in the working directory to be staged for the git commit.
SQL includes operators and functions for calculating values on stored values. SQL allows the use of expressions in the select list to project data, as in the following example, which returns a list of books that cost more than 100.00 with an additional sales_tax column containing a sales tax figure calculated at 6% of the price.
Git does periodic repacking automatically, but manual repacking is also possible with the git gc command. [46] For data integrity, both the packfile and its index have an SHA-1 checksum [47] inside, and the file name of the packfile also contains an SHA-1 checksum. To check the integrity of a repository, run the git fsck command. [48] [49]
A COMMIT statement in SQL ends a transaction within a relational database management system (RDBMS) and makes all changes visible to other users. The general format is to issue a BEGIN WORK (or BEGIN TRANSACTION , depending on the database vendor) statement, one or more SQL statements, and then the COMMIT statement.
SQL was initially developed at IBM by Donald D. Chamberlin and Raymond F. Boyce after learning about the relational model from Edgar F. Codd [12] in the early 1970s. [13] This version, initially called SEQUEL (Structured English Query Language), was designed to manipulate and retrieve data stored in IBM's original quasirelational database management system, System R, which a group at IBM San ...
Nonetheless, in systems such as Microsoft SQL Server, as well as connection technologies such as ODBC and Microsoft OLE DB, autocommit mode is the default for all statements that change data, in order to ensure that individual statements will conform to the ACID (atomicity-consistency-isolation-durability) properties of transactions.

git push uploads changes from local branches to the respective remote repositories. git add puts current working files into the stage (aka index or cache) git commit commits staged changes to a local branch git commit -a commits all modified files to a local branch (shorthand for "git add" and "git commit")
Databases and other data stores which treat the integrity of data as paramount often include the ability to handle transactions to maintain the integrity of data. A single transaction consists of one or more independent units of work, each reading and/or writing information to a database or other data store.
