http://Flexvie.ws fully implements a method for creating materialized views for MySQL data sets. The tool is for MySQL, but the methods are database agnostic. A materialized view is an analogue of software transactional memory. You can think of this as database transactional memory, or as database state distributed over time, but in an easy way to manage.
It has been shown that combinatorial algebraics can be applied to all aggregate functions (Flexviews uses only composable operations even for deletes over “non-distributable aggregate functions”), and Flexviews includes this capability today. Because Flexviews can move database objects forward in time synchronously with each other to specific points in time in database state, invalid database state is not possible, particularly if there are thorough database checks.
Flexviews is:
lock free for read
fully log based
supports all DML
supports all aggregate functions
supports join
supports NULL values
supports simple projection
only rolls forward in time right now
MVCC
row level locking with innodb
Flexviews was based on the following research:

citeseer.ist.psu.edu/viewdoc/summary?doi=10.1.1.41.7788
Also includes my own personal and extensive research into combinatorial algebra over non-distributable aggregate functions. I was not aware of research into combinatorial algebra and developed these techniques in isolation from other researchers as I am an amateur.
