object persistence formats Sequential access optimized for operat.pdf
0 likes4 views
The document discusses various object persistence formats, highlighting their efficiency in operations such as sequential access and specific object retrieval. It contrasts object-oriented databases, which support complex data and inheritance, with object-relational databases that extend relational models to include user-defined data types. Additionally, it notes the learning curve associated with these technologies and their varying support for inheritance based on programming languages.
