It is pretty easy to gather status information from all sorts of things,
ranging from the temperature in your office to the number of octets which
have passed through the FDDI interface of your router. But it is not so
trivial to store this data in a efficient and systematic manner. This is
where RRDtool kicks in. It lets you log and analyze the data you gather from
all kinds of data-sources. The data analysis part of RRDtool is based
on the ability to quickly generate graphical representations of the data
values collected over a definable time period.

Action Record
In Rails, the model is handled by what's called a object-relational
mapping layer entitled Active Record. This layer allows you to present
the data from database rows as objects and embellish these data objects
with business logic methods.

SQLite is an SQL database engine in a C library. Programs that link the SQLite
library can have SQL database access without running a separate RDBMS process.
The distribution comes with a standalone command-line access program (sqlite)
that can be used to administer an SQLite database and which serves as an
example of how to use the SQLite library.
Mission:
Development of an open-source solution for asynchronous, master-master
replication of relational databases that is
- ridiculously easy to use
- database independent
Currently supports PostgreSQL and MySQL.
SFCGAL is a C++ wrapper library around CGAL with the aim of supporting ISO
19107:2013 and OGC Simple Features Access 1.2 for 3D operations.
SFCGAL provides standard compliant geometry types and operations, that can be
accessed from its C or C++ APIs. PostGIS uses the C API, to expose some
SFCGAL's functions in spatial databases
