 DATABASE LEARNING MODULE
In the relational data model the database is represented as a group of related tables.
In addition, the relational data model is not as biased towards a particular kind of structure as the hierarchical model.
If you will never want to access the data by city, by state or by zip code then it may be appropriate to have the entire address in one field, but if you want to sort by zip code, for example, then it is not appropriate to put the entire address in one field.

 Relational Algebra
This type of languages are used to retrieve, store, manipulate data, create forms, queries, reports and application programs.
The users of these languages do not need to tell the system how to find the results, all they have to do is to ask for the end result they want.
For example SQL is a nonprocedural language and assume that we have a table (file) of employee and we want to find the names and phones of all female employees who make less than $30,000 per a year.

 Web Query Languages, Intelligent Information Integration   (Site not responding. Last check: 2007-10-14)
Data is not strongly typed which means that attributes with the same name may change type as they are used in different places.
These languages were not developed for the web and do not distinguish between graph edges that connect within a document and a hyperlink to another document.
The language was suggested by the authors to fill the void of extracting and integrating data from XML sources into a web client.

 Querying XML data : the DQL language
DQL is an extension of OQL for the manipulation of tree-like and forest-like data.
Developing such languages is a hard task, due to the complexity of the structures which are involved (e.g.
In this poster, we propose a new XML data manipulation language: the DQL language which is an extension of OQL for the manipulation of tree-like and forest-like data.

 Database Journal: Daily Database News, Information and Tutorials for the Database Professional
Most data definition/manipulation languages, including SQL, are constructed to return and manipulate data in two dimensions, commonly seen as a row dimension and a column dimension.
To identify and extract the data, whether it is for a single cell or multiple cells, MDX uses a reference system based upon the concept of tuples.
The WHERE statement is used to restrict the returned data to a slicer dimension (which is composed of specific dimension and member criteria, and is expected to return data for a single member).

 Software for Manipulating or Displaying NetCDF Data
If the data points are not evenly spaced on a rectangular grid, IVE must be informed of the grid structure, either by specifying "attributes" in the data input or by specifying the coordinate transform in a user supplied subroutine.
A general mathematical data model that can be adapted to virtually any numerical data, that supports data sharing among different users, different data sources and different scientific disciplines, and that provides transparent access to data independent of storage format and location (i.e., memory, disk or remote).
IDL (Interactive Data Language) is a scientific computing environment that combines mathematics, advanced data visualization, scientific graphics, and a graphical user interface toolkit to analyze and visualize scientific data.

 data manipulation language - Simple XML Data Manipulation Language (SiXDML) for Apache Xindice Announ
The SiXDML language is similar to SQL and DL/I in that it is a combination data definition and data manipulation language for XML databases.
The SiXDML language is designed to be easily understood by programmers and non-programmers alike, internet-aware, and combine a minimum of complexity with a maximum of functionality while being straight-forward to implement.
SiXDML aims to plug the hole that currently exists for a data manipulation language that allows one to query and update XML documents while also providing a means to perform database management activities.

 data manipulation languages - Re: Data manipulation languages for XML (was Query Languages ...)
However, when using the term "document" to mean "an abstraction of a container for information", which is the usual everyday meaning of "document", then the document is not a new document, unless the user considers it to be one.
Note the difference: I'm talking about the mechanics of data manipulation as related to the formal definition of SGML and XML, users are thinking about the abstractions of information creation.
For the purpose of thinking about standards for defining document processing, it is a very useful simplification to think of every change as creating a new *grove* (which, if used to generate an SGML or XML character string, would result in a new SGML or XML document).

Different data manipulation languages (such as SQL or XQuery), proprietary data languages, and sources with no query language that require use of a general purpose pro- gramming language (e.g., Java)
Data correlation determines if two objects, usually from different data sources, refer to the same real-world object.
Often, however, the sender and receiver use different terms for the same concepts, so that the data must be transformed to meet the needs of the receiver.

 Generic Interoperability Framework
By the term "generic" we mean that the semantics of protocols, languages and data remain preserved.
Instead of choosing a common model and language which are required to be supported by all components of a mediation architecture, individual protocols, languages and data are transformed into a generic representation retaining their ontological variety.
Instead of specifying common protocols, languages or data models we suggest an RDF-based representation in which protocols, languages and data are represented in a generic manner but still maintain their diversity and ontological specifity.
