SmallSQL is a 100％ pure Java DBMS, a relational database for Java desktop applications. It has a JDBC 3.0 interface and offering many ANSI SQL 92 and ANSI SQL 99 features. It is very small and fast Java library. It does not have a network interface.
In this paper, we consider the problem of filtering in relational
hidden Markov models. We present a compact representation for
such models and an associated logical particle filtering algorithm. Each
particle contains a logical formula that describes a set of states. The
algorithm updates the formulae as new observations are received. Since
a single particle tracks many states, this filter can be more accurate
than a traditional particle filter in high dimensional state spaces, as we
demonstrate in experiments.
LiteSQL is a C++ library that integrates C++ objects tightly to relational database and thus provides an object persistence layer. LiteSQL supports SQLite3, PostgreSQL and MySQL as backends. LiteSQL creates tables, indexes and sequences to database and upgrades schema when needed.
Let the following relational tables be given: R = (A, B, C) and S = (D, E, F) where A, B, C, D, E, and F are the attributes (columns). Write the SQL statements that will express each of the queries given below:
Learn how to leverage a key Java technology used to access
relational data from Java programs, in an Oracle environment.
Author Donald Bales begins by teaching you the mysteries of
establishing database connections, and how to issue SQL queries
and get results back. You ll move on to advanced topics such as
streaming large objects, calling PL/procedures, and working
with Oracle9i s object-oriented features, then finish with a look at
transactions, concurrency management, and performance
