Database creation and statistical analysis: finding connections between two or more secondary storage devices
نویسندگان
چکیده
We have created a database to analyze digital data to find connections between two or more different secondary storage devices. We used MongoDB and created a document for each secondary-storage image and each unique sector. Ingesting the secondary-storage images took so much time that we had to carefully consider all the reasons for the slow down and experiment on different ways to insert the data. Using a partial database, we found the fraction of space that is empty (contains NULLS), per secondary-storage image and for the entire database. We found duplicate images. Future students may continue to grow the database. Rather then make the goal a completed database, the students will analyze the current data and add to the database.

Hierarchies of Indices for Text
| We present an eecient implementation of a recently known index for text databases, when the database is stored on secondary storage devices such as magnetic or optical disks. The implementation is built on top of a new and simple index for texts called pat array (or suux array). Considering that text searching in a large database spends most of the time accessing external storage devices, we ...
متن کاملNumerical Analysis of Cyclic Behavior of Beam-To-Column Bolted Connections in Steel Frames
This article considers the seismic behavior of beam-to-column joints in steel frames for different bolt arrangements by using of finite element modeling. As the most important beam-to-column joint type, the beam-to-column joints with end-plate is chosen for the analysis. Four different specimens have been analyzed. These models had some differences such as bolt arrangement and the presence or a...
متن کاملDatabase Systems for Efficient Access to Tertiary Memory
Tertiary storage devices have long been in use for storing massive amounts of data in le-oriented mass storage systems. However, their use in database systems is relatively new. Database systems associate more structure to the data than just raw sequence of bytes. Hence if they are allowed control of the tertiary memory devices, they can greatly reduce access cost by doing more informed caching...
متن کاملA Survey on Intertextual and Intersemiotic Relations between the Sechischti Lyrics and the Kilims of the North Khorasan’s Kurmanj Nomads
Diverse artistic media in a nomadic community, despite their differences, represent the familiar traditions and beliefs of their creators. Text is a dynamic site in which relational processes and practices are the focus of analysis instead of static structures and products. Every text is an intertext that borrows, knowingly or not, from the immense archive of previous culture. Intersemiotic tra...
متن کاملAn Analytical Solution to a MEMS Seek Time Model
The huge disparity between memory access times and disk access times has been the subject of extensive research. CPU speed has been increasing rapidly but disk access latency has lagged behind—disk transfer rates have been increasing at 40% per year, while seek times and rotational latency have been increasing at less than 10% per year [4]. This disparity has created a performance bottleneck in...
