The impact of Information and Communication Technologies on business models is posing new challenges. It has given birth to a new set of data and related applications. Changing business needs and the explosion of digital data have also created huge demand for massive and efficient storage. Increasing costs for electronic data storage and limited funds made people to think about cloud storage. S...

In this paper, we review many of the technical issues that must be addressed in developing high-quality optical disk recording media. The geometric design of tracking grooves and embossed data on the disk substrate must be optimized to the characteristics of the optical drive to support robust data seeking, track following, and data addressing. To ensure adequate recording performance and drive...

Human-beings have always been fond of accessing more and more information in minimum possible time and space. Consequently New Generation Computers and High Speed Internet have gained popularity in the recent years. We have been witness to remarkable achievements like the transition from the bulky hard-drives to the flash drives which has made personal data storage efficiently manageable. But w...

The data storage and retrieval services utilized by the ECS services layer will be provided by both a Database Management System (DBMS) and a hierarchical le system (see Figure 2.1). The DBMS(s) will manage and provide access to structured data as well as certain types of unstructured data (e.g., text data), whereas the le system will provide direct access to the large data sets that will be pr...

Efficient Archival Data Storage

Introduction: NASA’s future missions would require massive high-speed onboard data storage capability to Space Science missions. For Space Science, such as the Europa Lander mission, the onboard data storage requirements would be focused on maximizing the spacecraft’s ability to survive fault conditions (i.e. no loss in stored science data when spacecraft enters the “safe mode”) and autonomousl...

We see a world where personal system software is self-installing, self-configuring, self-personalizing, self-administering, and self-healing. In this world, personal system data is visible in a single name space regardless of " owning " application and data location, supports uniform non-procedural query, transactions, and security, is automatically backed up, is recoverable, and supports porta...

Provenance research has generally focused on issues with data collection and organization. Most approaches represent stored provenance data as a directed acyclic graph (DAG), where objects such as files and processes are nodes in the graph and directed edges specify ancestry relationships between them. While there has been some work addressing logical compression of these provenance graphs, eff...

The CLEO III experiment will collect on the order of 200 TB of data over the lifetime of the experiment. The challenges facing CLEO III are how to store such a large dataset. We will describe our experiences with Objectivity/DB on top of a Hierarchical Storage Manager.

Most data retrieval mechanisms in wireless sensor networks adopt a data-centric approach, in which data is identified directly by name rather than through the location of the node on which it is stored. Initial data-centric methods, such as directed diffusion and TinyDB/TAG, focused on the conveyance of data. One of the advantages of these algorithms is that they do not require pointto-point ro...
