This suggests SQL Server only can provide transparency of replication, fragmentation and language. A hierarchy of these transparencies is shown in Figure 2.1. It provides translations from the operating system to the higher-level user interface. The third layer at which transparency can be provided is the DBMS level. State-of-the-art operating systems provide some level of transparency to system users. The second layer at which transparency can be provided is the operating system level. It provides transparent access to data resources. The first layer at which transparency can be provided is the access level. The transparency services can be provided at three distinct layers.
With a fully transparent DBMS the developer needs not to pay much attention to deal with the kind of query which needs a distributed, fragmented and replicated database.
Transparency Management Transparent Management means how good the database distributed. Section 8 is the conclusion.įigure 1.3 : Distributed Database SoftwareĢ. Section 7 describes the difficulties when setting up the distributed SQL Server. Section 6 demonstrates the replication with SQL Server. Section 5 demonstrates fragmentation with SQL Server. Section 4 shows the distributed transaction with SQL Server. Section 3 describes the way SQL Server becomes distributed. Follows are the structure of the article. Meanwhile, discussing the terminologies in "Principles of Distributed Database System" and SQL Server is also the article main task. This article describes the different levels of distributed database to solve our confusion, and shows the ability of distributed SQL Server. A note of distributed SQL Server exits but without replication section and terminologies matching. The reasons come from a lot of distributed database product share the market based on figure 1.3. However, many different terminologies between SQL Server and the book cause the difficulties. First, reading the book "Principles of Distributed Database System" to know the concepts and definitions, and then searching the keywords in MSDN to understand the distributed database with SQL Server. Therefore, are they distributed database? What level of distribution did this case have? Could they distribute better? 1ġ.2 Research Process We studied the distributed database from both theory and practical. For example, the SQL Server in Kaohsiung city couldn't query the database in Taipei city. They only uploaded their data through internet. Second, the market managers and the flower growers query the data originally in different location through OLAP.įigure 1.1 : Location of Five Databases and Auction Clocks In this case, five databases didn’t connect together directly through the internet due to the privacy issues.

The transaction data generated by Auction Clock won’t update after 12 A.M owing to transactions in all markets finished before 12 A.M.
#ADVENTURE WORKS DATABASE FOR SQL SERVER 2016 EXPRESS HOW TO#
How to differentiate the database system is the distributed database? Do they have the degree of distribution? For such a case in Taiwan is the distributed database because of different locations and the query ability? First, Five SQL Server databases located in five different flower markets and transmitted data in CSV file format to one data warehouse as figure 1.1. Introduction 1.1 Motivation Distributed database is vague for us. Advanced Database Group Project Distributed Database with SQL Server Hung Chang, Qingyi Zhu Erasmus Mundus IT4BIġ.
