An Alternative To Common Content Management Techniques [article]

Rares Vasilescu
2009 arXiv   pre-print
One of the most usual methods encountered in commercial products is to make use of the file system to store the raw content information, while the associated metadata is kept synchronized in a relational  ...  In this paper we propose an alternative method of storing and managing content aiming at finding solutions for current limitations both in terms of functional and nonfunctional requirements.  ...  For example, it is not advisable to store millions of file in the same "folder" inside a file system.  ...

The background of the DASDBS & COSMOS projects [chapter]

H. -J. Schek, M. H. Scholl, G. Weikum
1991 Lecture Notes in Computer Science  
The research objective is the exploration of the architecture of a COoperative System for the Management of ObjectS (COSMOS). In short, we are on the way "from the kernel to the cosmos". 1.  ...  While most emphasis in DASDBS was on a database kernel system, the project at ETH focuses on the cooperation between a database system and its environment.  ...  In particular, we have developed heuristic algorithms for dynamic file creations and file expansions in disk arrays [WZS90] , aiming at I/O parallelism to minimize the reponse time of file accesses and  ...

Object-oriented retrieval mechanism for semistructured image collections

Guang-Ho Cha, Chin-Wan Chung
1998 Proceedings of the sixth ACM international conference on Multimedia - MULTIMEDIA '98  
~, ,' q The facilities, e.g., query by example and query by keywords, rdlow novice users to query the database without knowing about the schema strucme.  ...  A collection of the derived signatures is called signature file.  ...  The main idea of the signature file is to derive propefiies of data objects, called signatures, and store them in a separate file. Signatures are hash-coded binary words of fixed Iength.  ...

Data Deduplication Methods: A Review

Gagandeep Kaur, Mandeep Singh Devgan
2017 International Journal of Information Technology and Computer Science  
When the dynamics of cloud services change over period of time, the ownership and proof of identity operations also need to change and work dynamically for high degree of security.  ...  The outcome of such developments is that the data gets duplicated and gets replicated rapidly especially when large number of cloud users are working in a collaborative environment to solve large scale  ...  The end customers are able to effectively store more data than the overall capacity of their disk storage system would allow.  ...

Database forensic analysis through internal structure carving

James Wagner, Alexander Rasin, Jonathan Grier
2015 Digital Investigation. The International Journal of Digital Forensics and Incident Response  
A significant amount of sensitive data is stored and processed in relational databases thus creating the need for database forensic tools that will extend file carving solutions to the database realm.  ...  Forensic tools assist analysts with recovery of both the data and system events, even from corrupted storage.  ...  We also present a tool that, given a disk image or a RAM snapshot can do the following: e Identify intact DBMS pages, even for multiple DBMSes on the same disk, for all known storage configuration parameters  ...

A survey of RDF storage approaches

David C. Faye, Olivier Curé, Guillaume Blin
2012 ARIMA  
In recent years RDF has been a widespread data format for the Semantic Web.  ...  There is a real need to efficiently store and retrieve RDF data as the number and scale of Semantic Web in real-word applications in use increase.  ...  These systems can be broadly classified as persistent disk-based and main-memory-based systems. The persistent disk-based storage is a way to store RDF data permanently on file system.  ...

Workload matters

Güneş Aluç, M. Tamer Özsu, Khuzaima Daudjee
2014 Proceedings of the VLDB Endowment  
The Resource Description Framework (RDF) is a standard for conceptually describing data on the Web, and SPARQL is the query language for RDF.  ...  Existing systems are workload-oblivious, and are therefore unable to provide consistently good performance. We propose a vision for a workload-aware and adaptive system.  ...  As a case study, consider gStore, which creates a signature entry for each vertex in the adjacency list based on the corresponding values in the list, and stores these signatures in a VS-tree for efficient  ...
