  • cytosine arabinoside — cytarabine.
  • database transaction — (database)   A set of related changes applied to a database. The term typically implies that either all of the changes should be applied or, in the event of an error, none of them, i.e. the transaction should be atomic. Atomicity is one of the ACID properties a transaction can have, another is isolation - preventing interference between processes trying to access the database cocurrently. This is usually achieved by some form of locking - where one process takes exclusive control of a database table or row for the duration of the transaction, preventing other processes from accessing the locked data. The canonical example of a transaction is transferring money between two bank accounts by subtracting it from one and adding it to the other. Some relational database management systems require the user to explicitly start a transaction and then either commit it (if all the individual steps are successful) or roll it back (if there are any errors).

  • environment variable — (programming, operating system)   A variable that is bound in the current environment. When evaluating an expression in some environment, the evaluation of a variable consists of looking up its name in the environment and substituting its value. Most programming languages have some concept of an environment but in Unix shell scripts it has a specific meaning slightly different from other contexts. In shell scripts, environment variables are one kind of shell variable. They differ from local variables and command line arguments in that they are inheritted by a child process. Examples are the PATH variable that tells the shell the file system paths to search to find command executables and the TZ variable which contains the local time zone. The variable called "SHELL" specifies the type of shell being used. These variables are used by commands or shell scripts to discover things about the environment they are operating in. Environment variables can be changed or created by the user or a program. To see a list of environment variables type "setenv" at the csh or tcsh prompt or "set" at the sh, bash, jsh or ksh prompt. In other programming languages, e.g. functional programming languages, the environment is extended with new bindings when a function's parameters are bound to its actual arguments or when new variables are declared. In a block-structured procedural language, the environment usually consists of a linked list of activation records.
