A relatively simple multilayered database built on top of standard file systems.
Project description
filesystem-database
This database is easy to set up: Just make an empty folder and initialize a dbNode
object in it! The database structure consists of dbNode
objects. dbNode
s contain more dbNode
s and keys, which store a byte value.
Usage
To initalize a database:
import filesystem_database as fs_db
rootNode = fs_db.dbNode('/path/to/database/directory')
The directory passed to dbNode()
must either be empty or contain only data from a dbNode
.
To use keys:
rootNode.mkKey(0, 'exampleKey') # Create a key with ID 0 and name `exampleKey`
rootNode.set(0, b'test data :D') # Set a value to key 0
rootNode.get(0) # Get the value of key 0 (returns `b'test data :D'` in this case)
rootNode.keys # A list containing key IDs
rootNode.keyNames # A dictionary containing key names and the key IDs they correspond to
Here 0
is the ID to give the key and 'exampleNode'
is the optional name to assign to the key. Neither the ID nor the name may be used for multiple keys. get
and set
will accept either an integer for a key ID or a string for a key name.
To use nodes:
subNode = rootNode.mkNode(0, 'exampleNode') # Create a node under `rootNode`
rootNode.node(0) # Get node 0 from `rootNode`
rootNode.nodes # A list containing node IDs
rootNode.nodeNames # A dictionary containing node names and the node IDs they correspond to
subNode
is a dbNode
object whose contents are within rootNode
. Here 0
is the ID to give the node (must not be taken) and 'exampleNode'
is the optional name to assign to the node. Neither the ID nor the name may be used for multiple nodes. get
and set
will accept either an integer for a key ID or a string for a key name. get
and set
will accept either an integer for a node ID or a string for a node name.
