DAS C++ Status
Actually is being developed the Tuscany DAS C++. So far, the framework can
perform the following:
- Convetion Over Configuration(COC):
- DAS assumes that a column named xxx_id is a FK to the column named
id on table xxx.
- If no PK column is found on the ResultSet, it sets the column named
id as PK, if exists.
- The COCs defined above are, actually, case sensitive and, for
example, a column named ID will not be set as PK
- The das is using the ResultSet metadata(column name, column data type and
column table) to generate the sdo graph and popule it. The DAS guarantees
the table object uniqueness on graph basing on the table PK, so the first
table retrieved by the ResultSet will be taken, and any other table
containing the same PK ignored:
- A table may contain a simple PK or a composite one.
- If no PK is defined for the table, the DAS tries to find one using
COC.
- If the table has a composite PK and not all the columns that
compound the PK are contained on the ResultSet, the DAS ignores the defined
composite PK and tries to find another PK using COC as defined above.
- If no PK is found using COC, the DAS sets all columns on ResultSet
as PK.
- Setting the references on graph objects basing on table relationships.
- Actually, there may be up to 1 relationship between 2 tables.
- The columns data that compound the FK are not created on the graph.
- The DAS accepts simple or composite relationships.
- If not all the columns, PK or FK, that compound the relationship are
on the ResultSet, the relationship is ignored and the remaining FK are
loaded onto graph.
- Actually, the DAS config can only be set from code.
- There are also implemented some testcases.
- DAS is only supporting the following SQL types: INTEGER, REAL, CHAR,
VARCHAR, FLOAT, DOUBLE.
Next steps:
- Read the config from a xml file.
- To implement a sample that reads some data from a database and print on
console.
- Implement support for more SQL types.
Comments and suggestions will be appreciated : )
Any volunteer would be helpful ; )

Adriano Crestani
Re: DAS C++ Status
Posted by Adriano Crestani <ad...@apache.org>.
The SimpleRead sample was remade and renamed to CompanySamples. Not it
demonstrates not only how to load data from rdb to SDO graph, but how to
modify the graph and apply the changes back to the rdb.
DAS GettingInvolved and sample Readme are updated to these new changes.

Re: DAS C++ Status
Posted by Adriano Crestani <ad...@apache.org>.
DAS C++ has now its own exceptions, such as DASInvalidTypeNameException,
DASInvalidPropertyNameException, DASNullPointerException,
DASColumnNotFoundException, DASInvalidColumnNameException,
DASInvalidRelationshipNameException, DASInvalidSQLTypeException and
DASInvalidTableNameException.

Re: DAS C++ Status
Posted by Adriano Crestani <ad...@apache.org>.
DAS C++ is now non-case sensitive, once most dbms are non-case sensitive,
DAS C++ will be so, at least for now. Maybe on future, there can be added an
option on config file that set DAS as case sensitive.
All type and property names are converted to lower case when the SDO graph
is created.

Adriano Crestani

Yes, it's intergrated with Tuscany SDO C++.
Next step is to implement a sample for it.
I intend to add some info on wiki before the first release.

Hi Adriano,
Is this integrated with SDO C++? Is there a sample for it?
Can more information be added to the home page and user guide[1]?
