Database Replication ~ Slony-I Configuration in Windows XP

Describing database replication, postgresql replication, replication configuration, Slony-I configuration, Slony-I windows xp, replication performance, master slave replication, database performance, Slony-I in pgAdmin, asynchronous replication, replication and synchronization

Replication is a common thing for databases that require more performance. One of open source solution that can be used in replication is Slony-I. This system works with the concept of asynchronous data thus inconsistency between master and slave database. That is the consequences that must be accepted, but the positive thing is the performance of these systems can be inherently better for the data transmission process performed on a periodic basis so as not to burden the system as a whole (there is a choice between functionality and performance, it is difficult to get both).

Open Source

Describing about open source, open source projects, open source softwares, open source solutions, open source communities, open source business, open source trends, open source world, open source programming and open source organizations.

Do you know about open source ? It's a kind of popular buzzwords right now ? Yeah, open source become one of good alternative solution for IT Industry.
When people together build something without knowing each other and sharing the source of what they build, they just did open source programming. So many motives for doing that but clearly it would be good for us.
