Introduced forty years ago, relational databases proved unusually
succe- ful and durable. However, relational database systems were
not designed for modern applications and computers. As a result,
specialized database systems now proliferate trying to capture
various pieces of the database market. Database research is pulled
into di?erent directions, and speci- ized database conferences are
created. Yet the current chaos in databases is likely only
temporary because every technology, including databases, becomes
standardized over time. The history of databases shows periods of
chaos followed by periods of dominant technologies. For example, in
the early days of computing, users stored their data in text ?les
in any format and organization they wanted. These early days were
followed by information retrieval systems, which required some
structure for text documents, such as a title, authors, and a
publisher. The information retrieval systems were followed by
database systems, which added even more structure to the data and
made querying easier. In the late 1990s, the emergence of the
Internet brought a period of relative chaos and interest in
unstructured and "semistructured data" as it
wasenvisionedthateverywebpagewouldbelikeapageinabook.However, with
the growing maturity of the Internet, the interest in structured
data was regained because the most popular websites are, in fact,
based on databases. The question is not whether future data stores
need structure but what structure they need.
