  Types of softwareOffice Automation David Asirvatham End-user Software Application software Systems software Systems Develop. Tools Used for a specific type of business process. E.g billing systems, inventory system End-User Software General purpose software. E.g. word processor spreadsheet, etc Systems Develop. Tools Used for the construction of other business applications e.g. compilers. DBMS, etc Controls the operation of a computer e.g. Windows95, UNIX, etc Application Software System Software

  Application Software Applicationsoftware perform the functions required by the users e.g. word-processor, graphics, CAD, Animation Effective software should be: free from errors or bugs flexible (can handle a range of transactions; changing OS, etc) performance (response time) Examples General purpose: Ms-word, Excel, OpenOffice, etc Special purpose: ATM application, accounting package, etc Office Automation David Asirvatham

  Systems Software: OperatingSystems Generally, these software are hidden from the users Most of the resident programs are OS modules The main module of the OS is the monitor program. Its functions include: memory allocation and management multi-user scheduling access control I/O control providing utilities and user services OS performs four main functions: controlling of all devices and components of the computer carry out all utility routines performs translation to machine code (compatible to the OS) supports networking & communication Office Automation David Asirvatham

  Operating Systems Examples:Windows XP, 98 and windows 2003 Linux Unix (e.g. Solaris) IBM OS/2 McOS Office Automation David Asirvatham

  Development Tools Thesesoftware supports the programmers Users can also use it to write their own modules It involves the writing, storing and execution of programs The main functions are: load program into the memory (loaders) links modules together (linkers) permits modification of program codes (editors) e.g Visual Basic, Visual C++, PHP, Java, etc Office Automation David Asirvatham

  Programming languages Machinelanguage instructions, in binary, that directly controls the computer processor depended; different machines will different machine codes not human recognisable; difficult to read or understand Assembly language written in symbolic rather than numerical machine code An assembler is used to translate it to machine code High-level language machine independent more efficient development of software procedural language and more English-like easy to user and understand Office Automation David Asirvatham
• 9.
  Programming Language Fourthgeneration language non-procedural language easy to use closer to natural language main features prototyping query language (oracle-SQL) report gemerators application generator E.g PowerBuilder, FOCUS, NOMAD and RAMIS Office Automation David Asirvatham

  Evolution of ProgrammingLanguages Office Automation David Asirvatham First Generation 1940s (Machine language) Difficult to learn and use Long instructions Machine Dependent Second Generation 1950s (Assembly language) Difficult to use for large programs Shorter codes than ML Machine Dependent Third Generation 1950s (COBOL, C++) English-like Problem Oriented Easy to use Fourth Generation 1980s (Foxpro, Dbase) More English-like Many Functions Incl. Data Management Easy to use Natural language Future Use of natural language Voice-recognition

  Off-the shelf vsin-house development Software can be obtained in three different ways: off-the-shelf third party software developers (consultants) in-house development Off-the-shelf suitable for well-established software like word-processors, graphics packages, small database, etc e.g. MS-Office, Lotus Smartsuite, Macromedia Director, etc general applications difficult to customers cheaper upgrade version are available available immediately user-friendly; user-support, documentations Office Automation David Asirvatham

  Off-the shelf vsin-house development Consultant suitable if the necessary skills are not available internally drawback: consultant may not have sufficient experience may require more time future enhancement can be expensive support; documentation; enhancement of software In-house should have a programming team within the company staff must be of high-caliber, reliable and well trained expensive; proper documentation is needed; time consuming easy to maintain; future upgrades; tailor-made Office Automation David Asirvatham

  Selection of SoftwareUser friendly Compatibility (platform, other packages) Editing facilities Text, graphics, GUI and others options import/export capability Media option (interface with various peripherals) Interactivity (branching, menu, hot spots) Management capabilities (database, folder organisation) Cost (incl. Upgrades) Others: Support, Reliability, number of users, hardware & memory requirements, training, installation, Documentation, etc Networking (ability to share the software/files) Office Automation David Asirvatham

  Office Automation Themain reason for the application of IT in office environment is to increase productivity Productivity can be improved in the following ways: better utilisation of workforce (lesser number, higher output per person) improve utilisation of time improve quality of management through better decision-making increase output through better individual performance greater effectiveness through the use of Information Office Automation David Asirvatham

  Benefits of OADirect benefits better control over work fewer conversion from one form of information to another fewer non-productive activities (filing, recording, updating) better personal organisation (less travel and less meetings) Office Automation David Asirvatham

  Benefits of OAIndirect benefits less dependency on other departments less need for procedures and control increased individual job satisfaction greater customer satisfaction Office Automation David Asirvatham

  OA Technology Telecomputingwork from at home save commuting time greater flexibility in working hours significant reduction in interruptions reduction in office space welfare support facilities travel expenses Office Automation David Asirvatham
• 23.
  OA Technology Facsimilescanning and transmission of the documents can verify signatures and can transmit graphics or pictures uses telephone lines Teleconferencing allow organisation to conduct presentation, meetings and negotiations 80% of Fortune 500 companies are using or planning to use it still expensive to high quality video conf. system Office Automation David Asirvatham
