NetCDF ( Network Common Data Form) is a set of software libraries and self-describing, machine-independent data formats that support the creation, access, and sharing of array-oriented scientific data. The project homepage [2] is hosted by the Unidata program at the University Corporation for Atmospheric Research (UCAR).
Hierarchical Data Format (HDF) is a set of file formats (HDF4, HDF5) designed to store and organize large amounts of data.Originally developed at the U.S. National Center for Supercomputing Applications, it is supported by The HDF Group, a non-profit corporation whose mission is to ensure continued development of HDF5 technologies and the continued accessibility of data stored in HDF.
The inverted file data model can put indexes in a set of files next to existing flat database files, in order to efficiently directly access needed records in these files. Notable for using this data model is the ADABAS DBMS of Software AG, introduced in 1970. ADABAS has gained considerable customer base and exists and supported until today.
In "modern dBASE", a .dbf file consists of a header, the data records, and the end-of-file marker. The header contains information about the file, such as the number of records and the number of types of fields used in the records. The records contain the actual data. The end of the file is marked by a single byte, with value 0x1A. File header
ARC – Nintendo U8 Archive (mostly Yaz0 compressed) ARJ – ARJ compressed file. ASS, SSA – ASS (also SSA): a subtitles file created by Aegisub, a video typesetting application (also a Halo game engine file) B – (B file) Similar to .a, but less compressed. BA – BA: Scifer Archive (.ba), Scifer External Archive Type.
This is a list of file signatures, data used to identify or verify the content of a file. Such signatures are also known as magic numbers or Magic Bytes. Many file formats are not intended to be read as text. If such a file is accidentally viewed as a text file, its contents will be unintelligible.
History. Unlike other database vendors, IBM previously produced a platform-specific Db2 product for each of its major operating systems. However, in the 1990s IBM changed track and produced a Db2 common product, designed with a mostly common code base for L-U-W (Linux-Unix-Windows); DB2 for System z and DB2 for IBM i are different.
