The Systems Development Life Cycle (SDLC) is a structured methodology used for developing information systems in a phased manner, ensuring systematic progress from project initiation to deployment and maintenance. It encompasses several phases including planning, analysis, design, development, testing, implementation, and maintenance, providing a framework that guides the successful delivery of a software system (Dennis, Wixom, & Roth, 2020). SDLC aims to enhance project management efficiency, reduce risks, and ensure that the final system effectively meets user requirements and organizational goals.

The Database Life Cycle (DBLC) is a subset of the SDLC focused specifically on the development, implementation, and ongoing management of databases. It includes phases such as requirements analysis, design, implementation, testing, deployment, and maintenance of databases (Coronel & Morris, 2015). The DBLC fits within the SDLC as a specialized process that supports the broader system development by ensuring the database components are effectively designed and integrated into the overall information system. This alignment facilitates data consistency, integrity, and security, which are vital for reliable system performance.

Within the SDLC framework, the DBLC typically occurs during the analysis, design, and implementation phases. During analysis, database requirements are identified based on system needs. The design phase involves creating the database schema and data models. Implementation involves constructing the database, populating it with data, and integrating it into the system architecture. Ongoing maintenance ensures data accuracy, performance optimization, and security over the database’s lifespan. Thus, the DBLC is integral to the SDLC, providing a structured approach to database management that complements the development of the entire information system.

Understanding the role of the database professional is crucial in ensuring smooth SDLC and DBLC processes. For example, a Database Administrator (DBA) plays a vital role in managing the organization's databases, ensuring their availability, performance, and security. A DBA reports to the IT manager or director and oversees database administrators and developers (Higgins, 2018). Their key tasks include database installation, configuration, backup and recovery, performance monitoring, and security management.

Job advertisements for a DBA often highlight essential skills such as proficiency in database management systems like Oracle, SQL Server, or MySQL, along with skills in scripting, troubleshooting, and data security. Their responsibilities include implementing database policies, ensuring data integrity, optimizing performance, and supporting application development teams. The role demands a comprehensive understanding of database architecture, security protocols, and disaster recovery plans, making it a critical component in ensuring the operational stability of organizational data assets (Silberschatz, Korth, & Sudarshan, 2019).
