 | | Tangram is an object-relational mapper: it makes objects persist in conventional relational databases, in effect letting you use RDBMSes as if they were object databases. |
 | | Tangram supports inheritance (including multiple inheritance), polymorphism, object identity, relationships (including collections), load-on-demand, etc. It also gives access to the powerful query facilities found in RDBMSes via an intuitive object syntax. |
 | | In the second part I will explain how these issues are solved by Tangram, and how you use the module to essentially rid yourself of any persistence concerns. |
