The RDBMS is dead! Long live the RDBMS!
Just kidding.
The RDBMS is alive and well.
It's longevity in the data management space is assured.
However, its position in that space is in question.

Straight from the horse's mouth --
Traditional full text pattern searches are falling away as rapidly as the RDBMS. Pattern searches offer astonishing numbers of hits, but their utility ends there. These search methods cannot present any of the context or conceptual nature of the data behind their results, because they work only with text literals. Servers conducting these searches "guesstimate" matches after milliseconds of processing -- and thus, a vast percentage of reported "hits" are generally not hits at all. They are irrelevant or non-existent.
Learn how "Faceted Browsing" facilitates meaningful data access and highly relevant hits through its interrogation of entity descriptions. Learn how use of interactively configurable search times control just how much data is searched so that those "million" hits represent real data.

If the RDBMS come-down is news to you, take time to familiarize yourself with these other new changes in the data management milieu.
EAV is shorthand for Entity-Attribute-Value data model. The EAV model breaks data out of the limiting two dimensional table logic of the RDBMS, into collections of entities that have values attributed to them. Thus, many perceive EAV to provide true conceptual modeling of real world objects and information. Early implementations of the EAV models had their own shortcomings including lack of standardization (query language, API), wire protocol implementation, scalability, and so on. Neverthless, EAV had real staying power. Limitations were outweighed by this model's ability to handle data split across heterogeneous DBMS engines, database schemas, networks, and the like.
Learn about advances in the EAV model which essentially seal its fate as the dominant DBMS model for the foreseeable future.
