Key Concepts

Object Persistence

Object persistence is the concept of ensuring that the state of an object is maintained between different instances of a program. It involves storing the essential data and structure of an object in non-volatile storage, so it can be recreated or restored later in a different session or context.

Serialization

Serialization is the technique of converting an object into a format that can be stored or transmitted and later reconstructed. This process typically transforms the object's state into formats such as binary, XML, or JSON, making it possible to save the object on disk or send it over a network.

Deserialization

Deserialization is the reverse process of serialization, where stored data formats are reconverted into live objects in memory. This is fundamental for restoring persistent objects to their original state, ensuring that the reconstructed object maintains its behavior and data.

Object-Relational Mapping (ORM)

Object-Relational Mapping is a strategy used to bridge the gap between object models in application code and relational database models. ORM tools facilitate the automated persistence of objects by mapping class attributes to database columns, allowing developers to work with database data as if they were regular objects.

File-based Storage

File-based storage is a persistence strategy where object states are written to and read from files on a file system. This method is often simpler than using a database and can be suitable for applications with less complex data management needs, serving as an alternative means to maintain object state over time.
