These were later usurped by the relational model, which was contemporary with the so-called flat model designed for very small tasks.
Another contemporary of the relational model is the object-oriented database (OODB).
While the relational model is based on set theory, one proposed modification suggests fuzzy set theory (based on fuzzy logic) as an alternative.

 OODB   (Site not responding. Last check: 2007-10-15)
Atknison et al (1989) stated three reasons for the lack of development of the OODB: 1) the lack of common data model, 2) the lack of formal foundations, and 3) the lack of strong experimental activity.
Until recently OODB have not have a standard in which to build.
The consortium that is developing the standards for OODB changed its name to Object Data Management Group (Barry, 1998).

Luckily, a major benefit of many OODB solutions is the ability to start coding an application without immediate integration or prior knowledge of the OODB itself.
The UML diagram shown in Figure 1 is a first stab at the design, before I planned for a specific OODB solution.
However, ObjectStore certainly shared some of the OODB disadvantages I discussed in "Object-Oriented Databases Are Worth a Closer Look".

 Wiener, J.; Naughton, J.: Bulk Loading into an OODB: A Performance Study
The process of loading data into an OODB is complicated by inter-object references, or relationships, in the data.
These relationships are expressed in the OODB as object identifiers, which are not known at the time the load data is generated; they may contain cycles; and there may be implicit system-maintained inverse relationships that must also be stored.
W e introduce seven algorithms for loading data into an OODB that examine different techniques for dealing with circular and inverse relationships.

 Modeling Business Applications with the OODB Ownership Relationship (ResearchIndex)
In this paper, we present a formal model of "ownership" relationships in the context of an Object-Oriented Database (OODB) system.
As our motivation, we employ three scenarios involving various ownership relationships that exhibit a wide range of distinctions.

Astrophysical CATalogs Support System (CATS) of the Special Astrophysical observatory includes a large number of astrophysical catalogs (mostly radioastronomical) and allows users to select sources from the CATS by different parameters, to make cross-identifications with user's lists and to study radio spectra of radio sources.
AMASE is an online astrophysics catalog developed using object-oriented database (OODB) technology to help researchers locate multi-mission data in the NASA archives.
The ASTROVIRTEL Project, supported by the European Commission and managed by the ST-ECF on behalf of ESA and ESO, is aimed at enhancing the scientific return of the ESO/ST-ECF Archive.

Structured documents (e.g., SGML) can benefit a lot from database support and more specifically from object-oriented database (OODB) management systems.
We propose the notions of virtual schemas and virtual bases as a coherent way of integrating various features in OODB views.
A virtual schema is defined based on some existing (real) schema.
