IBM BLU Acceleration is a collection of technologies from the IBM Research and Development Labs for analytical database workloads.
 BLU Acceleration integrates a number of different technologies including in-memory processing of columnar data, Actionable Compression (which uses "approximate Huffman encoding" to compress and pack data tightly), CPU Acceleration (which exploits SIMD technology and provides parallel vector processing), and Data Skipping (which allows data that's of no use to the current active workload to be ignored).
 The term ‘BLU’ does not stand for anything in particular; however it has an indirect play on IBM's traditional corporate nickname Big Blue.
 (Ten IBM Research and Development facilities around the world filed more than 25 patents while working on the Blink Ultra project, which has resulted in BLU Acceleration.)
Organización Soriana is a Mexican public company and a major retailer in Mexico with more than 824 stores.
 Soriana is a grocery and department store retail chain headquartered in Monterrey, Nuevo León, Mexico.
 The company is 100% capitalized in Mexico and has been publicly traded on the Mexican stock exchange (Bolsa Mexicana de Valores), since 1987 under the symbol: "Soriana".
 Soriana is powered by IT Retail software.
Computer Associates Panvalet® (also known as CA-Panvalet) is a revision control and source code management system for mainframe computers such as the IBM System z and IBM System/370 running the z/OS and z/VSE operating systems.
 Unlike open-source solutions such as CVS, SVN or Mercurial, Panvalet is a closed source, proprietary system for versioning and control of source code such as Microsoft Visual SourceSafe on personal computers.
 It uses a client-server model where users check-out files to change and check them back into the repository when finished.
IBM License Use Management (LUM) is the IBM product for technical software license management.
 IBM LUM for AIX is delivered as a standard component of AIX and is available on many other Unix flavors and on the Windows platform.
 CATIA is probably the most used software that uses this license manager.
The IBM 4610, also known as SureMark, is a famous thermal point-of-sale printer manufactured by IBM, launched in 1996.
 It is used by major retailers such as Wal-Mart (in most countries, most notably United States and Mexico), Carrefour, Costco, Cencosud, Office Depot, Tesco, Best Buy, Chedraui, King Soopers (and Kroger affiliates), London Drugs and Soriana (Mainly formerly Gigante stores).
 It had replaced the famous IBM Printer Model 4.
Mwave was a technology developed by IBM allowing for the combination of telephony and sound card features on a single adapter card.
 The technology centers around the Mwave digital signal processor (DSP).
 The technology was utilized for a time to provide a combination modem and sound card for IBM's Aptiva line and some ThinkPad laptops, in addition to uses on specialized Mwave cards that handled voice recognition or ISDN networking connectivity.
 Similar adapter cards by third-party vendors using Mwave technology were also sold.
 However, plagued by consumer complaints about buggy Mwave software and hardware, IBM eventually turned to other audio and telephony solutions for its consumer products.
The IBM 3270 is a class of block oriented computer terminal (sometimes called "display devices") introduced by IBM in 1971 normally used to communicate with IBM mainframes.
 The 3270 was the successor to the IBM 2260 display terminal.
 Due to the text colour on the original models, these terminals are informally known as "green screen" terminals.
 Unlike a character-oriented terminal, the 3270 minimizes the number of I/O interrupts required by transferring large blocks of data known as data streams, and uses a high speed proprietary communications interface, using coaxial cable.
The IBM Printer Model 4 was a dot-matrix point-of-sale printer launched in 1991.
 It and its successor, the IBM 4610, are still used by retailers such as El Corte Inglés, Publix, Zara, and Ripley.
 The printer was discontinued in 2005.
The IBM 3705 Communications Controller is a simple computer which attaches to an IBM System/360 or System/370.
 Its purpose is to connect communication lines to the mainframe channel.
 It was a first communications controller of the popular IBM 37xx series.
 It was announced in March 1972.
 Designed for semiconductor memory which was not ready at the time of announcement, the 3705-I had to use 1.2 microsecond core storage; the later 3705-II uses 1.0 microsecond SRAM.
 Monolithic System Technology components, similar to those in S/370, were used.
IBM InfoSphere DataStage is an ETL tool and part of the IBM Information Platforms Solutions suite and IBM InfoSphere.
 It uses a graphical notation to construct data integration solutions and is available in various versions such as the Server Edition, the Enterprise Edition, and the MVS Edition.
