Data Retrieval - an overview | ScienceDirect Topics
Data retrieval refers to the process of reading, copying, or moving information on a system. Unauthorized data retrieval can occur due to poorly configured file and directory permissions, allowing unauthorized users to access sensitive data. Proper access permissions and encryption can help prevent unauthorized data retrieval.
Data Retrieval - an overview | ScienceDirect Topics
Data retrieval is commonly organised using relational database systems and normalised tables, but metadata, other than the primitive data types used for table columns, are often not available online nor standardised. Metadata concepts are often better representations of the world if they are based on hierarchical models such as object-oriented ...

Programming for I/O and Storage - ScienceDirect
2013年1月1日 · DMA, as introduced in section 1, refers to the transfer of data directly between I/O devices and system memory. The basic unit of data transfer in DMA mode is the data block. It is more efficient than the interrupt mode. In DMA mode, there is a data channel set up between the system memory and I/O devices.

2006年12月1日 · Data retrieval is a process of searching a list of desired data files that match users' query conditions and displaying the data using GUIs. This process is made possible when the Java-based application engine seamlessly interacts with the metadata component.
Web data retrieval and extraction - ScienceDirect
2003年3月1日 · BioKleisli enables on-line queries against integrated data sources but requires additional implementation of programs in order to use retrieval facilities provided by Web data servers [68]. The OPM multi-database system is based on the OPM [23] to design object views [21] of the sources and its query language OPM–QL, an OQL-like query language.
