Conceptual and Database Modelling of Graph Databases

Proceedings of the 20th International Database Engineering & Applications Symposium on - IDEAS '16, 2016
Comparing graph databases with traditional, e.g., relational databases, some important database features are often missing there. Particularly, a graph database schema including integrity constraints is not explicitly defined, also a conceptual modelling is not used at all.

2004
Temporality, or the time dimension is an essential aspect of the reality databases attempt to model and keep data about. However, in many database applications temporal data is treated in a rather ad hoc manner in spite of the fact that temporality should be an integral part of any data model.

Database Schemes and Databases

1991
We attempt a more rigorous definition of the relational database model based on /THAL 88/ as it was originally introduced by E.F. Codd /CODD 70/ using the theory of abstract data types /REI 84/ and especially the approach of /PDGG 88/, /VOSS 87/ and /DEAB 85/.

Database Support for Document and Multimedia Databases

2001
A number of emerging applications are increasing the importance of document and multimedia data. Electronic digital libraries, image and video repositories, and electronic commerce catalogs are all examples of these applications. At the same time, technological developments, such as the standardization of XML, the realization of broadband networks with

Database Versions to Represent Bitemporal Databases

1999
We present a new approach to implement an object bitemporal database where both valid-time and transaction-time are represented. It is based on the DataBase Version model, which allows an effcient management of object versions. This facilitates the manipulation of past events and allows a straightforward representation of branching evolution in valid ...
