a Hierarchical Database Manager
This paper describes a new algorithm2 dealing with databases. This algorithm allow to fully manage a database, but their most natural field of applications is the datawarehouse (OLAP). It lies on a de-normalized representation of the database. The data is stored in thesauruses and radix trees (a hierarchical representation of bitmaps) which have interesting properties.
متن کاملTaxMan: a server to trim rRNA reference databases and inspect taxonomic coverage
Amplicon sequencing of the hypervariable regions of the small subunit ribosomal RNA gene is a widely accepted method for identifying the members of complex bacterial communities. Several rRNA gene sequence reference databases can be used to assign taxonomic names to the sequencing reads using BLAST, USEARCH, GAST or the RDP classifier. Next-generation sequencing methods produce ample reads, but...
متن کاملImplementing a Distributed Real-Time Database Manager
Conventional database systems are typically not used in time-critical applications due to poor performance and lack of predictability. Compared with uaditional databases, database systems for such applications have the distinct feature that they must satisfy timing constraints associated with transactions. Transactions in real-time database systems should be scheduled considering both data cons...
متن کاملHyperFile, a Database Manager for Documents
Documents, pictures, and other such non-quantitative information pose interesting new problems in the database world. Such data has traditionally been stored in file systems, which do not provide the security, integrity, or query features of database management systems. We have developed HyperFile, a data server that provides query facilities (as well as some other database features) while main...
متن کاملThe Prometheus Taxonomic Database
In [13], a new model of plant taxonomy (Prometheus) was designed; it supports multiple overlapping classifications, and distinguishes the process of naming from classifying. The concepts identified in this taxonomic model necessitated the design of a new database model (POOM) to represent and manipulate the data. POOM is an extended object oriented model which emphasises relationships, thereby ...
