You are welcome to convert your object into some sort of persistable data structure (XML, JSON,
Serializable) and stuff it in some database column. Bear in mind that you will still need to deal with compatibility issues (e.g., Version 2 of your app changes a class, which now needs to deal with both Version 1 and Version 2 structures). Also bear in mind that, going this route, you lose a lot of database capabilities (e.g., querying on something in the object).
