Explain the difference between distributed databases and client/server architecture.

-

  Client/Server :

Client/server is developed to deal with various computing environments that have a large number of computers and servers connected together via a network. In this architecture, a Client is a user machine that provides the user interface and local processing capabilities. When any client requires additional functionality like database access, it can connect to a Server that is capable of providing the functionality needed by the client. Basically, a Server is a machine that provides services to the Client i.e user machine.



Distributed DBMS :

In Distributed DBMS, data is distributed over the geographical site. Each site is a complete database system site on its end but the different sites have to work together because if any user wants to access the data it can easily access data anywhere in the network as the data is stored at the user’s own computer.


 the difference between distributed databases and client/server architecture. 

  Client/Server :

1.  Client can access only one server at a time.

2.  It is difficult to manage.

3.  In this data is distributed across clients.

4.  Speed of accessing the database is poor as compared to Distributed DBMS.

5.  If somehow the server crashes, the whole system stops.

6.  Accessing data is easy to control.

7.  It is less expensive as compared to Distributed DBMS.

8.  Maintenance cost is low.


Distributed DBMS :

1. Users can access many sites simultaneously.

2. It is easy to manage.

3. In this data is distributed across sites.

4.  Speed of accessing the database is much better than Client/Server Architecture.

5.  The crash of one site does not stop the entire system.

6.  Accessing data is difficult to control.

7.  It is expensive.

8.  Maintenance cost is high.

Suppose that a data warehouse for Big-University consists of the following four dimensions: student, course, semester, and instructor, and two measures count and avg_grade. When at the lowest conceptual level (e.g., for a given student, course, semester, and instructor combination), the avg_grade measure stores the actual course grade of the student. At higher conceptual levels, avg_grade stores the average grade for the given combination. a) Draw a snowflake schema diagram for the data warehouse. b) Starting with the base cuboid [student, course, semester, instructor], what specific OLAP operations (e.g., roll-up from semester to year) should one perform in order to list the average grade of CS courses for each BigUniversity student. c) If each dimension has five levels (including all), such as “student < major < status < university < all”, how many cuboids will this cube contain (including the base and apex cuboids)?

a) A Snowflake Shema is shown in figure below: b) The specific OLAP operations to be performed: 1. Roll-up on course from course_id to department. 2. Roll-up on a student from student_id to university. 3. Dice on course, student with department ="CS" and university = "biguniversity" 4. Drill-down on a student from the university to student_name. c) N = 4 dimensions The cube will contain 54 = 625 cuboids.

Suppose that a data warehouse consists of the four dimensions; date, spectator, location, and game, and the two measures, count and charge, where charge is the fee that a spectator pays when watching a game on a given date. Spectators may be students, adults, or seniors, with each category having its own charge rate. a) Draw a star schema diagram for the data b) Starting with the base cuboid [date; spectator; location; game], what specific OLAP operations should perform in order to list the total charge paid by student spectators at GM Place in 2004?

Roll-up on location from location id to location name. 4. Roll-up on the game from game id to all. 5. Dice with status= “students”, location name= “GM Place”, and year=2004

Network topology Network topology refers to how the nodes and links in a network are arranged. A network node is a device that can send, receive, store, or forward data. A network link connects nodes and may be either cabled or wireless links. Understanding topology types provides the basis for building a successful network. There are a number of topologies but the most common are bus, ring, star, and mesh: A bus network topology is when every network node is directly connected to a main cable. In a ring topology, nodes are connected in a loop, so each device has exactly two neighbors. Adjacent pairs are connected directly; non-adjacent pairs are connected indirectly through multiple nodes. In a star network topology, all nodes are connected to a single, central hub and each node is indirectly connected through that hub.  A mesh topology is defined by overlapping connections between nodes. You can create a full mesh topology, where every node in the network is connected to every other
