A handy use of this operator is to alias a routine's return value to $_ and to do additional manipulation with it, such as printing or returning it to caller. Since the andthen operator short-circuits, statements on the right-hand side won't get executed, unless left-hand side is defined (tip: Failures are never defined, so you can handle them with this operator).

sub load-data {
rand > .5 or return ; # simulatedloaddatafailure;returnNil
( rand > .3 ?? ' error ' !! ' gooddata ' ) xx 10 # ourloadeddata
load-data . first : / good / andthen say " $ _ isgood " ;
# OUTPUT:«(gooddataisgood)␤»
load-data () andthen . return ; # returnloadeddata,ifit'sdefined
die " Failedtoloaddata!! " ;

The above example will print good data is good only if the subroutine returned any items that match /good/ and will die unless loading data returned a defined value. The aliasing behaviour lets us pipe the values across the operator.

The andthen operator is a close relative of Orchid Embroidery Illusion Dress Helmut Lang Outlet Visit New oLW4jld2kp
, and some compilers compile with to andthen , meaning these two lines have equivalent behaviour:

Data security in general deals with protecting specific chunks of data, both physically (i.e., from corruption, or destruction, or removal; e.g., see Cheap Classic Dakla Skirt in Navy Iro Choice Sale Online Popular For Sale 9XYu9z
), or the interpretation of them, or parts of them to meaningful information (e.g., by looking at the strings of bits that they comprise, concluding specific valid credit-card numbers; e.g., see Shop For Cheap Online Outlet New Arrival Asymmetric Striped Cotton Midi Skirt Navy Adam Lippes Outlet From China yt1zV

Change and access logging records who accessed which attributes, what was changed, and when it was changed. Logging services allow for a forensic database audit later by keeping a record of access occurrences and changes. Sometimes application-level code is used to record changes rather than leaving this to the database. Monitoring can be set up to attempt to detect security breaches.

and data integrity after recovery from a crash . A database transaction is a unit of work, typically encapsulating a number of operations over a database (e.g., reading a database object, writing, acquiring , etc.), an abstraction supported in database and also other systems. Each transaction has well defined boundaries in terms of which program/code executions are included in that transaction (determined by the transaction's programmer via special transaction commands).

See also: Data migration §Database migration

A database built with one DBMS is not portable to another DBMS (i.e., the other DBMS cannot run it). However, in some situations, it is desirable to move, migrate a database from one DBMS to another. The reasons are primarily economical (different DBMSs may have different For Sale Free Shipping Amazon Cheap Online Jay Godfrey Lace Mini Dress Free Shipping Classic 4TFocy
or TCOs), functional, and operational (different DBMSs may have different capabilities). The migration involves the database's transformation from one DBMS type to another. The transformation should maintain (if possible) the database related application (i.e., all related application programs) intact. Thus, the database's conceptual and external architectural levels should be maintained in the transformation. It may be desired that also some aspects of the architecture internal level are maintained. A complex or large database migration may be a complicated and costly (one-time) project by itself, which should be factored into the decision to migrate. This in spite of the fact that tools may exist to help migration between specific DBMSs. Typically, a DBMS vendor provides tools to help importing databases from other popular DBMSs.
