The key concepts covered in the Fundamentals of Database Systems 7th Edition include database design, normalization, SQL queries, transaction management, indexing, and data warehousing.
1 Explain architecture of Distributed Database systems? Also, explain the reasons for building distributed database systems?
Database systems can be either referential, flat or heiarchial.
The relationships between database applications DBMS and databases is as follows: Databases can be simple or complex. simple databases can be kept in a Microsoft Excel spreadsheet or they can be maintained in a user generated Microsoft Access database which can be programmed to query certain data that has been entered into that database over a period of time. Microsoft Excel and Microsoft Access are also applications that are used to build databases that can be incorporated into DBMS or Database Management Systems. These systems can be extremely complex or they can be simple meaning that maintenance to these systems is not demanding. If the DBMS is complex it may require an entire team of technicians and in some cases engineers.The relationship between users, database applications, databases, and Database Management Systems can be simplified even further - Users can access a database that has been created with a database application to query managed data that is a part of a uniform Database management system.
SQL server is a database developed by the Microsoft corporation. The database is built to exclusively work on Microsoft Operating systems like Windows XP, Windows 2000, Windows Vista etc. It works on all Windows based platforms, but it does depend on the Edition of SQL Server you are going to implement. For example you can run SQL Server Express on Windows Server, but you cannot run SQL Server Enterprise on Windows XP. It will only run on Windows Server systems.
Redundancy means duplicacy of data or repetitive data. In distributed database case the data is stored in different systems . So the answers is yes there can be redundancy of records / data.In distributed database , data is stored in different systems. Since the data is distributed there is redundancy of records.

There are currently 3 general categories of data base management systems in use today:relational database systemsmultidimensional database systems (often referred as 'cubes')object oriented database systemsPrior to the success of relational database systems (early 80's) there were also hierachical database systems and network (aka CODASYL) database systems.
