A Database Management System, or DBMS, is a program or set of programs for managing databases. It is responsible for
- providing storage for a structured, integrated, coherent collection of data
- allowing the collection of data to always represent the current state of some part of the real world
- providing the current state to an organisation which needs it to function
- ensuring that the current state is correctly represented
- allowing access to and use of the collection of data by one or more applications and/or users
- providing protection for crucial data for the organisation using it
These responsibilities are why a DBMS usually has
- data structure definition facilities with provision for specifying and enforcing relationships between different types of data.
- a data update facility
- query languages and tools
- provision for integrity checks
- access and concurrency management
- backup and recovery facilities
Little Database Systems
- adb
- a pure-tcl database engine with optional (non-pure) extensions to
MySQL and XML
- TclVSdb
- Very Simple Database package Native Tcl database facility,
written in Tcl
[Starbase.tcl]:
- A simple database
- RS: Here I want to explore how a database can be
implemented in the Tcl spirit of simplicity, and how far that approach takes
us
- ANSI color control
- tables of pre-defined columns, and something that
mimics [SQL] SELECT a bit
Pre-Relational Database Systems
- Berkeley DB
- Includes Tcl Extension for accessing all the functionality
[gdbm]:
Hybrid Database Systems
- Metakit
- has a wonderful Tcl binding that makes all the power of Metakit
available in a natural and intuitive way.
