Verwenden Sie die Versionskontrolle für Ihre Datenbankelemente?

Question

Ich habe das Gefühl, dass mein Geschäft eine Lücke hat, weil wir keinen soliden Prozess für die Versionierung unserer Datenbankschemaänderungen haben. Wir machen viele Backups, so dass wir mehr oder weniger abgesichert sind, aber es ist eine schlechte Praxis, sich auf diese Weise auf die letzte Verteidigungslinie zu verlassen.

Überraschenderweise scheint dies ein roter Faden zu sein. Viele Geschäfte, mit denen ich gesprochen habe, ignorieren dieses Problem, weil sich ihre Datenbanken nicht oft ändern und sie im Grunde nur versuchen, peinlich genau zu sein.

Aber ich weiß, wie die Geschichte ausgeht. Es ist nur eine Frage der Zeit, bis sich die Dinge einfach falsch anordnen und etwas verloren geht.

Gibt es hierfür bewährte Verfahren? Welche Strategien haben sich für Sie bewährt?

Answer 1

Ich kontrolliere das Datenbankschema mit Hilfe von Skripten für alle Objekte (Tabellendefinitionen, Indizes, gespeicherte Prozeduren usw.). Was die Daten selbst betrifft, verlasse ich mich einfach auf regelmäßige Backups. Dadurch wird sichergestellt, dass alle strukturellen Änderungen mit einem korrekten Revisionsverlauf erfasst werden, ohne dass die Datenbank bei jeder Datenänderung belastet wird.

Answer 2

Hier ist eine Beispiellösung für einen Trigger, der die Verfolgung von Änderungen an Datenbankobjekten (über DDL-Statements) in einer SQL Server 2005 / 2008 Datenbank implementiert. Ich enthalte auch ein einfaches Beispiel dafür, wie man die Verwendung des erforderlichen someValue xml-Tags im Quellcode für jeden auf der Datenbank ausgeführten SQL-Befehl und die Verfolgung der aktuellen Datenbankversion und des Typs ( dev , test , qa , fb , prod ) erzwingt. Man könnte es mit zusätzlichen erforderlichen Attributen wie , usw. erweitern. Der Code ist ziemlich lang - er erstellt die leere Datenbank + die benötigte Tracking-Tabellenstruktur + die erforderlichen DB-Funktionen und den auffüllenden Trigger, die alle unter einem [ga]-Schema laufen.

Answer 3

In unserem Unternehmen verwenden wir Skripte für Datenbankänderungen. Wenn ein Skript ausgeführt wird, wird sein Name in der Datenbank gespeichert und kann nicht mehr ausgeführt werden, es sei denn, die Zeile wird entfernt. Skripte werden auf der Grundlage von Datum, Uhrzeit und Codeverzweigung benannt, so dass eine kontrollierte Ausführung möglich ist.

Bevor die Skripte in der Live-Umgebung ausgeführt werden, werden zahlreiche Tests durchgeführt, so dass "Fehler" im Allgemeinen nur bei Entwicklungsdatenbanken auftreten.

Answer 4

FYI Dies wurde auch vor ein paar Tagen von Dana angesprochen ... Gespeicherte Prozeduren/DB-Schema in der Versionskontrolle

Answer 5

RedGate ist großartig, wir erstellen neue Snapshots, wenn Datenbankänderungen vorgenommen werden (eine winzige Binärdatei) und behalten diese Datei in den Projekten als Ressource. Wann immer wir die Datenbank aktualisieren müssen, verwenden wir das Toolkit von RedGate, um die Datenbank zu aktualisieren, und können auch neue Datenbanken aus leeren Datenbanken erstellen.

RedGate stellt auch Daten-Snapshots her. Ich habe zwar nicht persönlich mit ihnen gearbeitet, aber sie sind genauso stabil.
