the SQL Server is spread across several smaller servers 3-4 SQL Server 2000 and 2005 with the total of 70 DB inside those servers, what I'd like to do/build is to migrate them all into SQL Server 2008 in which I must make it redundant so that if one server failed for whatever reason, the other instance can just pick it up straight away.
Database information changes constantly, in our case there are hundreds of queries at any given moment. Because of this the actual database changes, and keeping a backup from even a few hours ago is just not enough. To remedy this, MySQL (and most other database systems) has an option for replication. Here is how it works: 2013-04-22 Redundancy in DBMS is when we store same information in different parts of the database, while this is not possible to remove Redundancy completely, it should be avoided whenever we can.
Följande bild visar en av definitionerna för REDUNDANT på engelska: Referensdatabas enhet. RAC Database system provides scalability and high availability. In order to provide large database computing power and maintain large workload, you need to extend the number of nodes. Most cluster frameworks today differ in terms of the maximum number of nodes they can handle. In this post, I am going to share one T-SQL script to find duplicate and redundant Indexes of the SQL Server. I have found some of the junior and intermediate Database Developers, who are creating multiple duplicates indexes which are decreasing the overall performance of the database.
Redundancy of databases simply means that for every database there is an redundant DBMS copy or copies. An easy way of understanding the need for redundancy is when your DBMS says that a database is Suspect. This usually means that you have to access your data from another source (Redundant) or a backup, becau

This is data redundancy. We design the database to avoid redundant information. Why do we use In this video, Emily Lisa and Anna Hoffman discuss how to make a database zone redundant in Azure SQL, and the High Availability benefits of the zone redundant configuration.

Replicates your data 3 times within a single physical location synchronously in the primary region. Replicates your data across 3 Azure Availability Zones synchronously in the primary region Introduction to Database Design. This article/tutorial will teach the basis of relational database design and explains how to make a good database design. It is a rather long text, but we advise to read all of it. Designing a database is in fact fairly easy, but there are a few rules to stick to.
Data redundancy is costly to address as it requires additional storage, synchronization between databases, and design work to align the information represented by different presentation of the same data. The problems associated with redundant data can be addressed by data normalization. Normalized tables generally can contain no redundant data because each attribute only appears in one table.
The database can significantly facilitate and accelerate the construction of accurate biochemical models. Database information changes constantly, in our case there are hundreds of queries at any given moment. Because of this the actual database changes, and keeping a backup from even a few hours ago is just not enough. To remedy this, MySQL (and most other database systems) has an option for replication.

When you will chose cities for all this different type of people, you may end up adding same city to hundreds of students, teachers and admin staff. Result is going to be same city name in different parts of database.
Is there any difference between them?
