An efficient and qualitative work using environments to software engineering management depend of structure, control and adequate use of the resources available to design and development. Between this resources is the versions manipulation of (sub)projects and component created in the engineering phases. Currently, the majority of the software engineering environments supports the versions mani...

We show how tag clouds can be used alongside more traditional query languages and data visualisation techniques as a means for browsing and querying databases. Our approach is based on a general, extensible framework that supports different modes of visualisation as well as different database systems. A number of demonstrator databases and interfaces will be used to show how tag clouds can be u...

We present a framework for grid database replication. Data replication is one of the most useful strategies to achieve high levels of availability and fault tolerance as well as minimal access time in grids. It is commonly demanded by many grid applications. However, most existing grid replication systems only deal with read-only files. By contrast, several relational database vendors provide t...

Since the MEDLINE database was released, the number of documents indexed by this entity has risen every year. Several tools have been developed by the National Institutes of Health (NIH) to query this corpus of scientific publications. However, in terms of advances in big data, text-mining and data science, an option to build a local relational database containing all metadata available on MEDL...

Metadata is important for the interpretation of scientific data, quality assessment and long term usability of data sets. The sharing of spectral data collections among research groups is uncommon and one of the reasons for this is the missing standardisation of the sampling process. Appropriate metadata serves the purpose of detailing the sampling procedure and the surrounding conditions durin...

With the increased popularity of XML, XML publishing of RDBs has been attracting a lot of research interests. One of typical approaches is to use a middleware system to render XML views over RDBs and to allow users to access data with XML query languages such as XQuery. The query processing is done efficiently by making the best of the querying power of RDBMSs. Namely, XML queries are translate...

The trend in Grid computing towards more data intensive applications, accessing more and more relational databases and requiring advanced integration of secondhand and publicly available data sources, is still upstanding. Rich metadata information about these data sources plays a vital role for efficient distributed data management. There is a lack of service oriented monitoring tools providing...

As moving to big data world where data is increasing in unstructured way with high velocity, there is a need of data-store to store this bundle amount of data. Traditionally, relational databases are used which are now not compatible to handle this large amount of data, so it is needed to move on to non-relational data-stores. In the current study, we have proposed an extension of the Mongo...

RODA is an open-source full-fledged digital preservation repository capable of ingesting, managing and providing continuous access to various types of digital objects, namely textdocuments, raster images, relational databases, video and audio. It is supported by open-source technologies and makes use of existing standards such as the OAIS [1], METS [2], EAD [3] and PREMIS [4].

the pioneer work of image compression/reconstruction based onfuzzy relational equations (icf) and the related works are introduced. theicf regards an original image as a fuzzy relation by embedding the brightnesslevel into [0,1]. the compression/reconstruction of icf correspond to thecomposition/solving inverse problem formulated on fuzzy relational equations.optimizations of icf can be consequ...
