Case #2: Database Management System Implementation at Salala Juices Ltd, Oman Salala Juices Ltd, a well-established juice brand with five factories across GCC countries, has been a regional favorite since its inception in 1990. The onset of the COVID-19 pandemic brought about a remarkable 53% surge in product sales, driven primarily by partnerships with food delivery giants like Akeed and Talabat. However, this surge in demand has ushered in heightened competition and amplified challenges in effectively managing the company's business processes and operations. One particularly pressing issue revolves around the handling of data, which has become increasingly burdensome and resource-intensive. Salala Juices lacks a structured mechanism for capturing, storing, processing, and visualizing data, especially data originating from a multitude of manual and automated sources. As the company engages with numerous individual and corporate customers, suppliers, and distribution partners, the volume of generated data has skyrocketed. The company currently struggles to harness this data efficiently to derive meaningful insights. To address this data management crisis, the senior management at Salala Juices has initiated a search for proposals from IT consulting firms to design and implement a comprehensive database management system.
