Please some opinion in the free partitioning for Oracle standard Edition project

Hi, if you have some feedback please this is the proyect basically, I hope be in this year
check it first please.

For every thing there is a function in a master package for every partitioned table, for example there is a function to create addition partitions

1. you have the table partitioned in several tables, every table is a partition, every one has the indexes it needs
2. the information about range of every partition is store in the partitions information table, the table name, and the range, and other info, there is a header table for partitioned tables is not in the scheme, sorry.
3. You can create global indexes, this are iot tables storing primary key, the table partition where its stored and the rowid in that table
4. how you query?
5. you have a view, union all of all tables, this give a transparent full access
6. you have a function table using the globalindextable
7. you have a function table which queries only the tables partitiosn you need, the primary key are parameter in the function table
8. To insert,update you use a temporary table, a funcion move data from the temporary table to the proper partition, based on the partitions information table
9. To delete there is function too, using the partitions table information

The main benefits are the fact
1. to create historic data, you can create a new partition and move it to a read only tablespace
2. you can improve the access in historic tables having a lot of historic rows which are rarely accessed

This doesn't too simple, but the performance improvement in big tables deserves the effort.
I either see really as a complex proyect to program, is true there will be lots of details, specially to add list partitioning, etc. If you have some idea about improving this free project partitioning concept, you are welcome.
