How Will Astronomy Archives Survive the Data Tsunami Case Study

How Will Astronomy Archives Survive the Data Tsunami - Case Study Example Archives operate within an environment where resources, mostly financial are limited (Chaisson & McMillan, 2011). When the response time for astronomy queries increases, so is the cost of obtaining data from the archives. This impresses on the need to search for further technological techniques, which are more efficient and cost effective. Various performance degradation issues associated with the growing trend are indicated by the archived astronomical data. First, there is growth in the usage of the archived data, increasing the access and queries associated with the archived data sets. This effectively reduces the efficiency of data access, while also increasing the response time involved in queries (Berriman & Groom, 2011). The decreased efficiency and increased response time has the effect of making the study into this field less efficient, thus discouraging the widening of the knowledge base in astronomy. Most significant is the fact that, the growth in archived astronomical da ta increases the demand for such data, encourages the creation of more sophisticated queries and analysis techniques, which in turn increases the storage, computation and database costs (Berriman & Groom, 2011). This serves to make the access to archived astronomical data more expensive for users. Additionally, the increased volume of archived astronomical data means that it is now more accessible, thus influencing the research undertaken in this field, since most researchers are now using the archived data to undertake their research, at the expense of newly acquired data (Chaisson & McMillan, 2011). This practice is detrimental to the growth of astronomy, since new research and enquiries are rarely made, thus making new discoveries and innovations in this field impractical. The effect of this is to limit the knowledge base of the astronomy field, while also enhancing the regurgitation of data and provision of redundant and irrelevant study findings (NRC, 2011). The essence of rese arch is to promote new enquiries and discoveries in certain field, with a view to creating new knowledge, while also enhancing creativity and innovation in solving the problems associated with the field (Berriman & Groom, 2011). With a continued publication of more papers using the archived data sets, the hope of new discoveries and innovations in this field is extinguished. The increased volume of archived astronomy data has also caused performance degradation of various astronomical data institutions such as NASA’s Infrared Processing and Analysis Center (IPAC) and Infrared Science Archive (IRSA), through affecting their reporting abilities (Berriman & Groom, 2011). Following these performance degradation issues, a need for alternative archival techniques has risen. One such alternative archival technique is graphical processing units (GPUs), which is a technique developed to enhance the output of an image that occurs on a display device (Berriman & Groom, 2011). Neverthele ss, while this technique is meant to help in reducing the inefficiencies associated with large volumes of archived astronomical data, the technique has proved to be ineffective due to various reasons. First, the technique is only applicable in graphic-like
