Dissertation Topics Architecture Technology Layer

Syracuse University Library launched its mobile website.  Optimized for iPhone, Android, and Blackberry smartphones, the website offers quick, convenient access to core library information sources, including hours, contact information, and locations.  No extra application is necessary; simply go to http://m.library.syr.edu/ from your smartphone.

  The mobile website allows users to:

  • Search the library catalog, WorldCat, JSTOR, and mobile versions of a number of Library databases
  • Find the locations of all SU libraries and collections
  • Get research help via text message, instant message, email, or phone
  • Check library hours
  • View floor maps of Bird Library
  • Browse the Library staff directory and automatically email or place a call to anyone listed
  • View library events

 The mobile website will continue to grow and develop based on your feedback.  Use the “Give us your feedback” link to convey your ideas and suggestions.

Topic 1: Big data storage allocation in Cloud computing

The challenge to efficiently archive and manage data is intensifying with the enormous growth of data. The demand for big data storage and management has become a challenge in today's industry. There are multiple types of information and the number of locations stored on the Cloud. Especially, an increasing number of enterprises employ distributed storage systems for storage, management and sharing huge critical business information on the cloud. The same document may be duplicated in several places. The duplication of documents is convenient for retrieval and efficient. However, it will be difficult to update multiple copies of same documents once the data has been modified. How does the data management provide the retrieval of data stored in different locations consistently, efficiently and reliably is a complicated task with multiple objectives.  One important open problem is how to make the systems load balancing with minimal update cost. Furthermore, how to make the systems be elastic for effectively utilizing the available resources with the minimal communication cost. Providing effective techniques for designing scalable, elastic, and autonomic multitenant database systems is critical and challenging tasks. In addition, ensuring the security and privacy of the data outsourced to the cloud are also important for the success of data management systems in the cloud.

Topic 2: Adopting NoSQL for Big data management

Big data is well on its way to enormous. It has the great potential to utilize big data for enhancing the customer experience and transform their business to win the market. Big data enables organizations to store, manage, and manipulate vast amounts of data to gain the right knowledge.

Big data is a combination of data-management technologies evolved over time.

How does a company store and access big data to the best advantage?  Are traditional DBs  still the best option? What does it mean to transform massive amounts of data into knowledge? Obviously, the big data requirements are beyond what the relational database can deliver for the huge volume, highly distributed, and complex structured data. Traditional relational databases were never designed to cope with modern application requirements — including massive amounts of unstructured data and global access by millions of users on mobile devices that require geographic distribution of data.

In this research, we will identify the gap between Enterprise requirements and traditional relational database capabilities to look for other database solutions. We will explore the new technology NoSQL data management for big data to identify the best advantage. We will gain an insights into how technology transitions in software, architecture, and process models are changing in new ways.

Topic 3:Top-k queries in uncertain big data

Effectively extracting reliable and trustworthy information from Big Data has become crucial for large business enterprises. Obtaining useful knowledge for making better decisions to improve business performance is not a trivial task.  The most fundamental challenge for Big Data extraction is to handle with the data certainty for emerging business needs such as marketing analysis, future prediction and decision making. It is clear that the answers of analytical queries performed in imprecise data repositories are naturally associated with a degree of uncertainty.  However, it is crucial to exploit reliability and accurate data for effective data analysis and decision making. Therefore, this project is to develop and create new techniques and novel algorithms to extract reliable and useful information from massive, distributed and large-scale data repositories.

Topic 4: Feature-based recommendation framework on OLAP

The queries in Online Analytical Processing (OLAP) are user-guided. OLAP is based on a multidimensional data model for complex analytical and ad-hoc queries with a rapid execution time. Those queries are either routed or on-demand revolved around the OLAP tasks. Most such queries are reusable and optimized in the system. Therefore, the queries recorded in the query logs for completing various OLAP tasks may be reusable. The query logs usually contain a sequence of SQL queries that show the action flows of users for their preference, their interests, and their behaviours during the action.

This research project will investigate the feature extraction to identify query patterns and user behaviours from historical query logs. The expected results will be used to recommend forthcoming queries to help decision makers with data analysis. The purpose of this research is to improve the efficiency and effectiveness of OLAP in terms of computation cost and response time.
