DBLC (DataBase Life Cycle):

  • DBLC is a sequential process which is used to trace the history of the application that is present within the information system.
  • The history of the application can be traced from the beginning till its last even though being outdated.
  • DBLC is concurrent to Software Development Life Cycle (SDLC) because the database represents the core of the information system.
  • It is composed of six phases:
    • Initial study:
      • Examining the operations of the current system.
    • Design:
      • It focuses on designing the database model which satisfies both operation and objectives of the company.
    • Implementation and loading:
      • It is a process of designing the specifications.
    • Testing and evaluation:
      • Ensure the database performance.
    • Operation:
      • The process that is designed to make it operational.
    • Maintenance and evolution:
      • Performs routine maintenance activity within the database.

using r language in an accelerated failure test, components are operated under extreme conditions so that a substantial number will fail in a rather short time. in such a test involving two types of microships 600 chips manufactured by an existing process were tested and 125 of them failed then 800 chips manufactured by a new process were tested and 130 of them failed what is the 90%confidence interval for the difference between the proportions of failure for chips manufactured by two processes? using r language
