DESCRIPTION |
DESCRIPTION |
125 |
Data::Storage is a module for accessing various "data structures" stored |
Data::Storage |
|
inside various "data containers". It sits on top of DBI and/or Tangram. |

reserved. |
We tried to use the AdapterPattern (http://c2.com/cgi/wiki?AdapterPattern) to implement a wrapper-layer |
130 |
|
around core CPAN modules (Tangram, DBI). |
131 |
|
|
132 |
|
Why? |
133 |
|
|
134 |
|
You will get a better code-structure (not bad for later maintenance) in growing Perl code projects, |
135 |
|
especially when using multiple database connections at the same time. |
136 |
|
You will be able to switch between different _kinds_ of implementations used for storing data. |
137 |
|
Your code will use the very same API to access these storage layers. |
138 |
|
... implementation has to be changed for now |
139 |
|
Maybe you will be able to switch "on-the-fly" without changing any bits in code in the future.... |
140 |
|
... but that's not the focus |
141 |
|
|
142 |
|
What else? |

- some kind of security layer for methods/objects |
227 |
|
- acls (stored via tangram/ldap?) for functions, methods and objects (entity- & data!?) |
228 |
|
- where are the hooks needed then? |
229 |
|
- is Data::Storage & Co. okay, or do we have to touch the innards of DBI and/or Tangram? |
230 |
|
- an attempt to start could be: |
231 |
|
- 'sub getACLByObjectId($id, $context)' |
232 |
|
- 'sub getACLByMethodname($id, $context)' |
233 |
|
- 'sub getACLByName($id, $context)' |
234 |
|
( would require a kinda registry to look up these very names pointing to arbitrary locations (code, data, ...) ) |
