Grep versus FlatSQL versus MySQL
We designed and implemented FlatSQL, a SQL-like query language for operating on flat files, and compared its performance to MySQL and grep. Our performance measurements help to determine which tool is appropriate under what circumstances. FlatSQL is convenient for many tasks because it works on text files and has SQL syntax, but its performance is inferior to MySQL for non-trivial indexed relat...

In the near future, mobile devices are expected to have a storage capacity comparable to today’s desktop machines. As the amount of infomation grows, conventional search tools become less effective. To meet these challenges, we turn to desktop search. This paper presents Dessy, aDESktop Search directorY system for mobile and desktop computers alike.

Contemporary file systems implement a set of abstractions and semantics that are suboptimal for many (if not most) purposes. The philosophy of using the simple mechanisms of the file system as the basis for a vast array of higher-level mechanisms leads to inefficient and incorrect implementations. We propose several extensions to the canonical file system model, including explicit support for l...
متن کاملSemi automatic indexing of PostScript files using Medical Text Indexer in medical education.
At Albert Einstein College of Medicine a large part of online lecture materials contain PostScript files. As the collection grows it becomes essential to create a digital library to have easy access to relevant sections of the lecture material that is full-text indexed; to create this index it is necessary to extract all the text from the document files that constitute the originals of the lect...
متن کاملEfficiently Querying the Indexed Compressed Xml Data (iqx)
Extensible Mark-up Language was designed to carry data which provides a platform to define own tags. XML documents are immense in nature. As a result there has been an ever growing need for developing an efficient storage structure and high-performance techniques to query efficiently. QUICX (Query and Update Support for Indexed and Compressed XML) is the compact storage structure which gives hi...
