Best File Compression Tools

Xtreme Compression is a radical data compression technology that delivers phenomenal
performance on discrete structured data. It achieves compression ratios and decompression speeds
that are beyond the reach of conventional methods.
Xtreme Compression features a set of proprietary data class-specific algorithms that exploit the
structure and complexity of multidimensional data. Our technology is content-aware, cognizant of
semantics, and capable of decorrelating along and across multiple dimensions simultaneously.
Xtreme Compression is less subject than conventional technology to information theory's
compressibility limits. That's why it outperforms the decades-old, one-dimensional, 'industry
standard' conventional methods still used to compress structured data.

What We Are and What We Do
Content-Aware Compression of Structured Data
Xtreme Compression, Inc. is a software design consultancy with special expertise in compressing
structured data. We apply our proprietary algorithms and source code to compress structured data
whenever performance beyond the reach of conventional methods is required.
Why We're Different, Smarter, and Better
We're different because our technology is content-aware, semantics-cognizant, and targets
structured data. We're smarter because we recognize and exploit the structure of redundancy. We're
better because we deliver more compression and faster decompression simultaneously.
Applications
Xtreme Compression targets in-memory DBMSs, analytics, business intelligence, data mining, data
warehousing, and other read-intensive applications with discrete structured data; plus wireless
devices, mobile apps, and infrastructures constrained by bandwidth, latency, memory, and/or
power.

Xtreme Compression's proprietary technology reduces storage costs and speeds data transfer and
program execution. Here is how:
‣ By concentrating more information into every physical word read from memory and processed
by the CPU, reducing the influence of the ‘von Neumann bottleneck’
‣ In SAN/NAS-type applications, by reducing spindle count to save power
‣ By reducing transmission time over links, networks, and other expensive-to-scale infrastructure
components
‣ By storing more information in internal caches to improve data locality and cache hit rates
‣ By increasing effective disk cache size to retrieve more real information from hard disk per read
operation
‣ By allowing storage on faster media (i.e., RAM vs hard disk, hard disk vs CD or DVD, local hard
disk vs network, etc.)
‣ By permitting more access data structures and paths for a given amount of storage

Attribute Vector Coding
Attribute vector coding is a content-aware vector transform method for compressing
multidimensional database tables. It works by recognizing semantic features in data. It breaks new
ground by capturing and exploiting the innumerable relationships, functional dependencies, and
statistical correlations in data without having to solve the intractable problem of explicitly
identifying and defining them as individual conditional mutual information terms.
Attribute vector coding recognizes the structure of redundancy, and produces complex structured
symbols that are fast to decompress. It achieves unequaled compression by systematically modeling
data at high levels of abstraction, across dimensions and data types. That makes it far less subject
than conventional methods to compressibility limits imposed by information theory.
Wordencoding
Wordencoding is a 0-order (context-independent) variable-to-variable-length algorithm for
compressing text strings in database table record fields. It achieves compression close to the 0-order
source entropy without sacrificing speed. It does that by efficiently maximizing effective combined
data locality over compressed record fields, lexicons holding strings, and access data structures.
Wordencoding deals explicitly with the structure and statistics of the data by recognizing that
redundancy in text strings exists at multiple levels of granularity.
