Abstract
Systems and methods for access to compressed data. A method includes initiating access to a lightweight data file for selected data and identifying data segments of the lightweight data file that correspond to the selected data. The method includes identifying a compression method corresponding to each of the identified data segments. The method includes accessing the identified data segments of the lightweight data file according to the identified compression methods.
Claims20
An apparatus for storage of computer aided design data, comprising:
- a data storage in which a lightweight data file is stored;
- and
- a controller coupled to the data storage, the controller configured to
- initiate access to a lightweight data file for selected data;
- identify data segments of the lightweight data file that correspond to the selected data;
- identify a compression method corresponding to each of the identified data segments;
- and
- access the identified data segments of the lightweight data file according to the identified compression methods.
A method performed by a controller, comprising:
- initiating access to a lightweight data file for selected data;
- identifying data segments of the lightweight data file that correspond to the selected data;
- identifying a compression method corresponding to each of the identified data segments;
- and
- accessing the identified data segments of the lightweight data file according to the identified compression methods.
A non-transitory machine-useable medium storing instructions that, when executed, cause a controller to:
- initiate access to a lightweight data file for selected data;
- identify data segments of the lightweight data file that correspond to the selected data;
- identify a compression method corresponding to each of the identified data segments;
- and
- access the identified data segments of the lightweight data file according to the identified compression methods.
