What are the Basic Stages of Database Development?

Introduction

It is hard to always avail perfect web development services from an organization that is fully aware of the basic knowledge of Database Development. There are plenty of database services around as IT infrastructure can’t run and work without a synchronized database.

Database consulting services can provide you an accurate market trending about the latest database software. IT companies are fully aware of the primary stages of database development. A brief description is also mentioned below for attaining the fundamental knowledge for a layman.

Database Development Process Phases

There are a series of phases, which include planning, requirement analysis, and implementation. Each procedure is divided into steps. The diagram of these phases is shown below:

1. Planning

The planning phase starts when there comes a customer request for database development. A set of activities that are required to be performed as follows concludes in the planning phase. Following are the steps involved in the planning phase, which are to be performed repeatedly:

• Reviewing and approving database project requests
• Prioritizing database project activities
• Allocating resources such as tools, money, people, etc.
• Arranging with the development team to accomplish the database project
• 
  

2. Requirement Analysis

This step is performed in order to understand an unresolved problem. This step is also an essential step in the database development as well as for the database consulting services. The person who is dealing with all the requirement analysis phase is known as a Database Analyst. All the requirements are collected and analyzed in this step. The following are the majorly performed activates in the requirement analysis phase:

• Problem perceptive or investigation.
• Requirements specification
• Developing a Conceptual Data Model
• Developing a Process Model
• Data Flow Diagram
• 
  

3. Design

This is the foremost phase of the database development process. The informational model created in the previous phase is designed into a conceptual schema for the database and to design an application. This is an essential phase of the process as it deals with the presentation of the software. The conceptual schema designs the data requirements collected for the analysis phase and is examined for an intangible database schema is produced, which is more important in the design phase of the database development process. The major steps in the design phase are:

• Database design
• Process design
• 
  

1. DBMS Selection

A suitable DBMS is selected in this step to support the information system. Numeral factors are involved in DBMS selection. Factors can be technological and cost-effective factors.

2. Technological Factors

The technological factors are apprehensive with the suitability of the DBMS information system, which includes the following:

• Nature of DBMS such as relational, object-oriented, etc.
• Storage structure and access methods supported by DBMS
• The interface is available for users and programmers.
• Type of query: Language Development tools
• 
  

3. Monetary Factors

The monetary factors deal with the expenditure of DBMS and to operate it, which includes:

• Software Cost
• Maintenance Cost
• Hardware Cost
• Database Creation and Maintenance Cost
• Training Cost

4. Implementation

Implementation is the last phase of database development, which is installed to use. All the information is installed according to the plan and design, as described in the previous phase. Implementation carries two steps:

• Database Definition
• Creating an application
• 
  

5. Maintenance

Maintenance is the process of monitoring as well as maintaining the database system. This includes activities like adding up new fields, re-sizing the existing file, adding new tables, etc. The requirements keep on changing with time. Thus, maintenance is mandatory and valuable.
