I want to setup transactional replication on sql server. By following the instructions of the ms replication preparation tutorial and the ms replication configuration tutorial, everything works fine.



My question is: Why all these 4 users? Will there be any trouble if instead of 4 I only use one windows user/db login for every step?

          If you use 1 user, you typically end up giving that user more access than it needs. By having the example use 4 different users, it helps demonstrate the good practice of using dedicated accounts for particular purposes. If one is compromised, there’s less impact on the overall system. If the example used just one user, everyone would assume it had to be that way.

          • OK, I understand your comments about "good practice", which is of course what the tutorial should instruct. However, this also implies that there is no concern (security aside), of damaging the functionality. Right?

This Kransekake is a traditional Scandinavian baker's confection. Confectionery is the art of making confections , which are food items that are rich in sugar and carbohydrates. Exact definitions are difficult. [1] In general, though, confectionery is divided into two broad and somewhat overlapping categories, bakers' confections and sugar confections. [2] Bakers' confectionery, also called flour confections , includes principally sweet pastries, cakes, and similar baked goods. Sugar confectionery includes candies ( sweets in British English), candied nuts, chocolates, chewing gum, bubble gum, pastillage, and other confections that are made primarily of sugar. In some cases, chocolate confections (confections made of chocolate) are treated as a separate category, as are sugar-free versions of ...
