Abstract: Embodiments of the present disclosure are directed to systems and methods for managing a database. In one or more examples, the system obtains input data comprising one or more data entries, where each data entry comprises one or more data items, and each data item comprises a field name and a field value. The system can generate a key-value set for each data item to obtain a plurality of key-value sets. Each key-value set includes at least a first key element comprising the field name of the respective data item and a second key element comprising the field value of the respective data item. The system can sort and store the plurality of key-value sets in the database. The system can further receive a query indicative of a field name or a field value, and generate, for display, an output based on retrieved key elements sets based on the query.
