Various database languages and database management systems are divided into the following categories. ) TP3 1 1. 132 database system: classified by type (general database systems are classified here. The specific database system is divided into TP3 1 1. 138. For special databases, please refer to TP392 note. ) Tp311.132.1hierarchical database tp31.132.2 mesh database tp31. Kloc-0/ 1.65438. 3 multimedia database tp311.135.1document database tp31.1. 038 database system: divided by system name (distinguished by the first two English letters of the database system name, arranged alphabetically. If the first two letters of the system name are the same, take the third letter. And so on. For example, the dBASE database is tp311.138db. ) TP3 1 1.5 software engineering tp31/programming automation TP3 1 1 .52 software development tp31.53 software maintenance (clock research TP3 1 1.54 software transplantation TP3 1 1.56 software tools, tool software (computer testing, compression and decompression, encryption and decryption, PCTOOLS, virus killing, etc. ) TP3 12 programming language, algorithm language (distinguished by the first two English letters of the language name, if the first two letters of the program language name are the same, the third letter is taken, and so on, for example, ALGOL language is TP3 12AL, and JAVA language is TP3 12JA. TP3 12AL comes before TP3 12JA. ) TP3 13 assembler (assembly language is included here. ) TP3 14 compiler, interpreter TP3 15 supervisor, management system TP3 16 operating system tp316.50089.000000000006.5 operating system: classified by type (generally refer to tp3/kloc-0. ) TP 3 16. 1 time sharing operating system TP3 16.2 real-time operating system TP3 16.3 batch processing TP3 16.4 distributed operating system.
