 Service-oriented architecture (SOA)  

Service-oriented architecture (SOA) is a software development model for distributed application components that incorporates discovery, access control, data mapping, and security features. Service-oriented architecture (SOA) is a software development model for distributed application components that incorporates discovery, access control, data mapping, and security features.


The use of services provides major benefits:

  • In contrast to the use of large applications, which tend to be “information silos” that cannot readily exchange information with each other, the use of finer-grained software services gives freer information flow within and between enterprises. Integrating major applications is often expensive. SOA can save integration costs.
  • Organizing internal software as services makes it easier to expose its functionality externally. This leads to increased visibility that can have business value, for example, when a logistics company makes the tracking of shipments visible to its customers, increasing customer satisfaction and reducing the costly overhead of status inquiries.
  • Business processes are often dependent on their supporting software. It can be hard to change large, monolithic programs. This can make it difficult to change the business processes to meet new requirements (arising, for example, from changes in legislation) or to take advantage of new business opportunities. Service-based software architecture is easier to change – it has greater organizational flexibility, enabling it to avoid penalties and reap commercial advantage. (This is one of the ways in which SOA can make an enterprise more “agile”.)

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?

  b) The specific OLAP operations to be performed are: 1. Roll-up on date from date id to year. 2. Roll-up on spectator from spectator id to status. 3. 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

Protection of Public Order and Decency  The internet is highly capable of being a saturated and versatile medium at the same time. Its reach is very vast and due to its multimedia capability, its impact can be immediate and profound. So the government has to beware of its potential to create a negative impact on society through the promotion of terrorism, pornography, communalism, violence, etc. Section 67 of the IT Act 2000 of India makes it a punishable offense to “publish or transmit or cause to be published it the electronic form, a material which is lascivious or appeals to the prurient ...
