Databases

=========
3

4
There are numerous specific mathematical databases either included
5
in Sage or available as optional packages. Also, Sage includes two
6
powerful general database packages.
7

8
Sage includes the ZOPE object oriented database ZODB, which
9
"is a Python object persistence system. It provides transparent object-oriented persistency."
10

11
Sage also includes the powerful relational database SQLite, along
12
with a Python interface to SQLite. SQlite is a small C library that
13
implements a self-contained, embeddable, zero-configuration SQL
14
database engine.
15

16

17
-  Transactions are atomic, consistent, isolated, and durable
18
   (ACID) even after system crashes and power failures.
19

20
-  Zero-configuration - no setup or administration needed.
21

22
-  Implements most of SQL92. (Features not supported)
23

24
-  A complete database is stored in a single disk file.
25

26
-  Database files can be freely shared between machines with
27
   different byte orders.
28

29
-  Supports databases up to 2 tebibytes (2^41 bytes) in size.
30

31
-  Strings and BLOBs up to 2 gibibytes (2^31 bytes) in size.
32

33
-  Small code footprint: less than 250KiB fully configured or less
34
   than 150KiB with optional features omitted.
35

36
-  Faster than popular client/server database engines for most
37
   common operations.
38

39
-  Simple, easy to use API.
40

41
-  TCL bindings included. Bindings for many other languages
42
   available separately.
43

44
-  Well-commented source code with over 95% test coverage.
45

46
-  Self-contained: no external dependencies.
47

48
-  Sources are in the public domain. Use for any purpose.
