Some scenarios require that a value be stored in a database column in one form and written to and read from the database column in another form. Servoy supports this requirement with a feature called Column Conversion and it has three applications: String Serialization, Blob Serialization and Global Method Conversion.
Servoy also allows the contribution of a column converter by a java plugin.

Servoy supports object persistence using String Serialization, which involves the conversion of a runtime object into a string format, which can then persist in a database column. When the column is read from the database, the persistent string will be deserialized back into a runtime object. Because Servoy uses JavaScript as its scripting language, runtime objects will be serialized into standard JSON format.
