Discuss the Impact of Data Quality Problems

(Databases behind MySpace, CH-6) cover the impact of data quality problems on MySpace as described in this case study. How did they calculate their data problems? What management, organization, and engine room issues had to be addressed? 1) hash out the impact of data quality problems on MySpace as described in this case study. Since the Site was launched in 2003, the favorable network site MySpace has baffle the worlds leading kind portal for connecting people who contact in connection with its content, and culture.MySpace projects an idea to its global community to experience the lucre by means of a social lens by integrating man-to-mans personal profiles, photo sharing, professional and entertainment videos, blogs, instant messaging, as well as hotshot of the largest music community. MySpace. com has been one of the fastest evolution sites on the Internet with 65 cardinal subscribers and 260,000 new users registering each day. all the same with their unexpected gr owth a presbyopic came the growth of other popular social networking sites such Face book and few other competitors which seemed to select gained ground, do to MySpace criticized performance.In its initial phases, MySpace ope outrankd with two network emcees communicating with one database server and a Microsoft SQL Server database. The site continued adding weather vane servers to handle change magnitude user requests and demands, once the number of accounts exceeded 500,000 the site added more SQL Server databases one served as a master database, and the others focused on retrieving data for users page requests. after two million accounts were activated, MySpace switched to a erect partitioning model in which separate databases supported distinct functions of the Web site, such as the log-in screen, user profiles, and blogs.Yet at just about point the separated functions get out still share data which will gain another problem to their list After three million accounts wer e reached, rather than investing in more sophisticated types of servers that could eventually solve their problems, the site scaled out by adding many cheaper servers to share the database workload which became just another shortcut option and not a long term solution for the company. 2) How did they solve their data problems? The Company eventually switched to a virtualized storage architecture in which databases write data into any uncommitted criminal record, therefore eliminating he possibility of an applications dedicated disk becoming overloaded. MySpace later installed a layer of servers between the database servers and the Web servers to enclose and serve copies of a great deal accessed data objects so that the sites Web servers wouldnt have to query the database servers with lookups as frequently. Unfortunately, MySpace still overloads more frequently than other major Web sites. With a log-in error rate of (20 to 40%) on some days, the site is not effectively organizing or storing data at all, reason for which the site may have been losing subscribers.After the review of this case study, we can see the Importance of Database Technology and the tint Data Quality provides to Websites and Social network sites and it can be mulish that their existence depend on it.. (Information based on, MySpace Case study and www. forbes. com) 3) What management, organization, and technology issues had to be addressed? Some of the problems MySpace has encountered are the inadequate storage distance on their database servers, slow access or no access through its log-in application, and the users inabilities to access data when requested.Over the years, MySpace has attempted to fix these problems by adding more Web/Database servers. Yet the main problem seems to be, adding the servers without restructuring the entire ashes in order to use their hardware and software more effectively. other major problem The MySpace Organization has faced its been their managemen t and personnel, Its well known that theyve had too many changes in personnel they were unceasingly hiring NET developers and losing them just as fast, which can create a defined unbalance for the company.In Jan, 2011 they announced a staff reduction by 47%. On the other hand they have dealt with numerous changes in management as well many of the important people who helped create The MySpace empire are now gone. Few to mention are, former death chair Tom Anderson who stepped down while CEO Chris DeWolfe was replaced by former Facebook murmur Owen Van Natta. The companys most recent plan is to energize itself in the (social networking space) by going back to what made them popular in the first place entertainment. ith hopes that a new focus on the entertainment media including television, movies, & music will help in making the social networking site reclaim its place on the web. Despite efforts of redesigning the site their users have decreased, as well as their popularity. In November 2010, the company fully unified with Facebook Connect calling it Mash Up with Facebook in an announcement wide seen, which in reality I believe is just the way of acknowledging Facebook is their 1 competitor and is currently dominating the social networking industry.In my Opinion their main weakness was with strategy implementation, they concentrated in what came up day to day, corresponding the additions of servers to support their users demand but they never really focused on priorities such as a solution to their Technical problems and the whole structural change it required. As time progresses business competitors will copy your carrefour or service and a lot of times they wont just copy, theyll Innovate and overpass the quality of whats already accessible therefore taking the place of 1 and not a competitor.
