Database Application Software - Essay Example

DATABASE APPLICATION SOFTWARE A database application Is a computer program whose primary purpose is entering and retrieving information from a computer-managed database. Early examples of database applications were accounting systems and Lorene reservations systems, such as SABER, developed starting In 1957. A characteristic of modern database applications Is that they facilitate simultaneous updates and queries from multiple users.

Systems in the sass might have accomplished this by having each user in front of a 3270 terminal to a mainframe computer. By the mid- 1 sass it was becoming more common to give each user a personal computer and have a program running on that PC that connected to a database server. Information would be pulled from the database, transmitted over a network, and then arranged, graphed, or otherwise formatted by the program running on the PC. Starting in the mid-sass it became more common to build database applications with a Web interface.

Rather than develop custom software to run on a user’s PC, the user would use the same Web browser program for every application. A database application with a Web Interface had the advantage that It could be used on devices of deferent sizes, with different hardware, and with different operating systems. Examples of early database applications with Web Interfaces Include Amazon. Com, which used the Oracle relational database management system, the photo. Et online community, whose implementation on top of Oracle was described in the book Database-Backed Web Sites (Jiff-Davis Press; May 1 997), and eBay, also running Oracle. [l] Electronic medical scores are referred to on importers. Com,[2] in December 2010, as “a software database application”. A 2005 Reilly book uses the term in its title: Database Applications and the Web. Some of the most complex database applications remain accounting systems, such as SAP, which may contain thousands of tables in only a single module. 3] Many of today’s most widely used computer systems are database applications, for example, Faceable, which was built on top of Messy. [4] The etymology of the phrase “database application” comes from the practice of delving imputer software Into systems programs, such as the operating system, compilers, the file system, and tools such as the database management system, and application programs, such as a payroll check processor.

On a standard PC running Microsoft Windows, for example, the Windows operating system contains all of the systems programs while games, word processors, spreadsheet programs, photo editing programs, etc. Would be application programs. As “application” is short for “application program”, “database application” is short for “database application aerogram”. Not every program that uses a database would typically be considered a “database application”.

For example, many physics experiments, e. G. , the Large Hadrons generate massive data sets that programs subsequently analyze. The data sets constitute a “database”, though they are not typically managed with a standard relational database management system. The computer programs that analyze the data are primarily developed to answer hypotheses, not to put information back into the database and therefore the overall program would not be
