This information be able to be used to found relationships between current applications and to identify uses of application information. It helps to identify future system requirements and to assess economic benefits of database system.

Feasibility Study- Afeasibility study engages preparing report on these following points: 

1. Technological feasibility- Is suitable skill offered to support database development?
2. Operational feasibility- Does a company have personnel, budget and internal expertise to create a database system successful?
3. Economic feasibility- Can benefits are identified? Determination desired system be cost-beneficial? Could costs and benefits be measured?

Requirements Definition- It involves defining scope of database identifying management and functional area information requirements and establishing hardware or software requirements.
Information requirements are determined from questionnaire responses, interviews with managers and clerical clients and reports and forms currently life form used.

Conceptual Design- conceptual design stage produces conceptual schema for database. Specifications are developed to a point where implementation is able to begin. Throughout this stage, detailed models of user view are created and integrated into conceptual data model recording all corporate data elements to maintain in database.

Implementation- During database implementation, DBMS is selected and acquired. Then detailed conceptual model is converted to implementation model of DBMS, data dictionary built, database populate, application programs developed and customers trained.

Database Evaluation & Maintenance- Evaluation involves interviewing users to determine but any data needs are unmet. Changes are made as needed. Over time system is maintained via introduction of enhancements and adding up of programs and data elements as business requests change and expands.
