Describe the 6 phases of the database life cycle

All of this should be done in accordance with the organization's security requirements.

Product lifecycle

Ever since, according to Elliott"the traditional life cycle approaches to systems development have been increasingly replaced with alternative approaches and frameworks, which attempted to overcome some of the inherent deficiencies of the traditional SDLC".

Developing a conceptual model: It is in this stage that all the logical design parameters of database operations are finalized, and the program development is carried out under a specified time period.

Identify pros and cons of the current system in-place, so as to carry forward the pros and avoid the cons in the new system.

A diagram used during the design phase of database development to illustrate the organization of and relationships between data during database design. A ten-phase version of the systems development life cycle [7] Not every project will require that the phases be sequentially executed.

Some of the questions that need to be answered include if the newly implemented system meets the initial business requirements and objectives, if the system is reliable and fault-tolerant, and if it functions according to the approved functional requirements.

Project managers have been taught that there are always two lifecycles at play on any project; these are Project and Product-oriented lifecycles. In addition to evaluating the software that was released, it is important to assess the effectiveness of the development process.

Maintenance The fifth stage of maintenance is usually a prolonged stage, representing the entire period which is allocated for testing, managing, troubleshooting and maintaining the features of developed database program.

Together these systems can significantly reduce sagging and cooling length needed in the line. If there are any aspects of the entire process or certain stages that management is not satisfied with, this is the time to improve.

Most pipe producers define as overweight the weight of the pipe bigger than determined by the centre of specification. Monitoring, modification, and maintenance 1. Maintenance The web development services not only make sure the installation of the application but they are also responsible for subsequent maintenance and upgrading if and when needed.

According to Taylor"the project life cycle encompasses all the activities of the projectwhile the systems development life cycle focuses on realizing the product requirements ". The SDLC is not a methodology per se, but rather a description of the phases in the life cycle of a software application.

The Open University is proud to release this free course under a Creative Commons licence. If your organization is looking to boost agility or improve business continuity by moving to a service-oriented architecture SOA this strategy may be worth pursuing - even though it is often the most expensive solution.

Some of the questions that need to be answered include if the newly implemented system meets the initial business requirements and objectives, if the system is reliable and fault-tolerant, and if it functions according to the approved functional requirements.

Upon the completion of this design stage, a complete database software package is made available, with all the technical limitations and loopholes addressed in the previous two stages. Scrutiny of the existing system: As benchmark and reference also included in the study was the neat PE virgin material.

Then see how the problem being studied fits in with them. The real code is written here. This new draft EN standard is set up as a system standard containing specifications for pipes, fittings and the fitness for purpose of the system.

Overview[ edit ] A systems development life cycle is composed of a number of clearly defined and distinct work phases which are used by systems engineers and systems developers to plan for, design, build, test, and deliver information systems.Based on the database model described in the Week 2 and Week 3 discussions for your business function Operation, and Maintenance and Evolution phases.

However, the actual implementation of each of the phases will phase of the Database Life Cycle, and describe the manner in which the chosen phase would change based on the size of 97%(). THE DATABASE LIFE CYCLE (DBLC): The Database Life Cycle (DBLC) contains six phases, as shown in the following Figure: database initial study, database design, implementation and loading, testing and evaluation, operation, and maintenance and evolution.

Key components of operational costs are unit price of infrastructure, the ability to match supply and demand, finding a pathway to optionality, employing an elastic cost base, and transparency. Software life cycle models describe phases of the software cycle and the order in which those phases are executed.

Each phase produces deliverables required by the next phase in the life cycle. The database development life cycle A core aspect of software engineering is the subdivision of the development process into a series of phases, or steps, each of which focuses on one aspect of the development.

(DDL) statements, which describe the database that needs to be implemented to meet the user requirements. Implementation. The Product Life Cycle Managing Your Product to Maximize Success The four phases usually used to describe a product's life cycle are: • Introduction • Growth • Maturity • Decline During the earlier parts of the product lifecycle, the cost of promoting the product may be larger than the revenue it brings in.
