DataMirror's New PointBase 5.1 Increases Database Performance by up to 30%.SANTA CLARA Santa Clara, city, Cuba Santa Clara (sän`tä klä`rä), city (1994 est. pop. 217,000), capital of Villa Clara prov., central Cuba. , Calif. -- Version 5.1 Delivers Optimized System Performance and More Powerful Synchronization DataMirror(R) (Nasdaq:DMCX) (TSX TSX Toronto Stock Exchange (TSE before April, 2002) TSX Transfer from Stack Pointer to Index TSX True Space Extension :DMC DMC Devil May Cry (video game) DMC Detroit Medical Center DMC Darryl McDaniels (rapper) DMC Destination Management Company DMC Del Mar College (Corpus Christi, TX) ), a leading provider of real-time, secure data integration solutions, today announced that it will generally release Version 5.1 of its PointBase technology on October 5, 2004. PointBase solutions are a core component of DataMirror's new Integration Suite 2005, a complete, end-to-end solution (jargon) end-to-end solution - (E2ES) A term that suggests that the supplier of an application program or system will provide all the hardware and/or software components and resouces to meet the customer's requirement and no other supplier need be involved. Compare: turn-key solution. that combines market-leading technology with unparalleled global services. This release includes PointBase Embedded(R), the world's leading 100% pure Java Refers to initiatives from Sun that specify 100% compliance with its Java specification. The goal is to maintain a consistent, single interface for Java so that all Java Virtual Machines can run all Java programs. See Holy Grail. relational database relational database Database in which all data are represented in tabular form. The description of a particular entity is provided by the set of its attribute values, stored as one row or record of the table, called a tuple. , and PointBase UniSync(R), a Java-based bi-directional data synchronization Keeping data in two or more computers up-to-date so that each repository contains the identical information. Data in handheld devices and laptops often require synchronization with the data in a desktop machine or server. solution. The new features introduced in Version 5.1 include hash join The Hash Join is an example of a join algorithm and is used in the implementation of a relational database management system. The basic problem of a join algorithm is to find, for each distinct value of the join attribute, the set of tuples in each relation which display functionality, log file encryption, and many-to-many join filters. DataMirror's PointBase 5.1 addresses customer demand for increased database performance, heightened operational efficiency, and improved usability. With PointBase 5.1, developers can increase production usage through improved database performance and customers can more precisely specify mobile data to reduce synchronization time and make optimal use of memory on handheld devices. "PointBase 5.1 enables customers to improve the overall performance and efficiency of their systems-requirements that our customers have voiced the need for," says Nigel Stokes, CEO (1) (Chief Executive Officer) The highest individual in command of an organization. Typically the president of the company, the CEO reports to the Chairman of the Board. , DataMirror. "In fact, with PointBase 5.1, customers can expect to experience up to a 30 percent increase in database performance. The improved performance, functionality, and usability delivered through this new release demonstrate our ongoing commitment to setting high performance standards for our solutions, giving our Integration Suite 2005 a strong competitive edge in the market." DataMirror's PointBase 5.1 includes the following new and enhanced features and benefits: PointBase Embedded - Hash Joins: This feature includes memory-based algorithms (as opposed to disk-based algorithms), which identify a set of rows within a table or a subset of a table and store the selected rows in a hash table A lookup table that is designed to efficiently store non-contiguous keys (account numbers, part numbers, etc.) that may have wide gaps in their alphabetic and numeric sequences. Hash tables are created by using a hashing function (algorithm) to hash the keys into hash buckets. , improving the performance of large, multi-table joins and reporting applications and providing users with the fastest, most efficient path to entries. - Optimized System Performance: Significant enhancements have been made to the cache manager, B-tree, and table page structure, resulting in performance improvements of up to 15 percent for insert, select, and delete functions and 30 percent for update functions. This increased optimization enhances overall system performance and allows users to improve database management. - Truncate To cut off leading or trailing digits or characters from an item of data without regard to the accuracy of the remaining characters. Truncation occurs when data are converted into a new record with smaller field lengths than the original. Table: This functionality allows users to efficiently, rapidly, and conveniently remove all rows in a table, supporting file-level operation and ensuring referential integrity A database management safeguard that ensures every foreign key matches a primary key. For example, customer numbers in a customer file are the primary keys, and customer numbers in the order file are the foreign keys. constraints remain intact. - Enhanced Security: Database log files can now be optionally encrypted, satisfying stringent security requirements. PointBase UniSync - Enhanced Join Filters: This solution now accommodates many-to-many join filters, in addition to conventional one-to-many joins, providing users with increased flexibility and expressibility of data associations. This feature extends PointBase UniSync's lead as the most expressively powerful, easy to use synchronization solution for enterprise data. - Data Compression data compression Process of reducing the amount of data needed for storage or transmission of a given piece of information (text, graphics, video, sound, etc.), typically by use of encoding techniques. : Data that is sent via TCP/IP TCP/IP in full Transmission Control Protocol/Internet Protocol Standard Internet communications protocols that allow digital computers to communicate over long distances. during synchronization can now be compressed, reducing message traffic and improving synchronization performance, particularly in low bandwidth deployments.
