What is multimedia database? What are the nature of multimedia database and applications?

Multimedia Database 

A multimedia database is a collection of related multimedia data. Common multimedia data types that can be found in a multimedia database include the following:  
 • Text
 • Graphics: drawing, sketches, and illustrations 
• Images: color and black & white pictures, photographs, maps, and paintings
 • Animation sequences: animated images or graphic objects
 • Video:  a  sequence  of images  (frames),  typically  recording  a  real-life  event  and  usually produced by a video recorder
 • Audio: generated from an aural recording device 
• Composite multimedia: a combination of two or more of the above data type 

Multimedia Database Applications 

Multimedia database applications are different from traditional database applications in the structure of the multimedia objects and media where the multimedia objects are stored and retrieved.  Multimedia data is diverse with different characteristics.  Because of the audio-visual nature of multimedia data types,  they are usually complex data composed of other data that can also be complex.  Aygun,  et al. indicated that multimedia objects are multidimensional and hierarchically structured, and can have some relations among them. For example, image data does not have temporal behavior because there is no time associated with it, while the video has both temporal and spatial behavior because the image sequences of the video should be displayed in order and in some dedicated time.

Multimedia Database Applications

Documents and record management: Industries that keep a lot of documentation and records. Ex: Insurance claim industry.

Knowledge dissemination: Multimedia database is an extremely efficient tool for knowledge dissemination and providing several resources. Ex: electronic books

Education and training: Multimedia sources can be used to create resources useful in education and training. These are popular sources of learning in recent days. Ex: Digital libraries.

Real-time monitoring and control: Multimedia presentation when coupled with active database technology can be an effective means for controlling and monitoring complex tasks. Ex: Manufacture control

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?

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
