# Best Other Non-Relational Databases Software

*By [Shalaka Joshi](https://research.g2.com/insights/author/shalaka-joshi)*


The other non-relational databases category encompasses products that deliver relevant functionality but do not align precisely with G2’s defined subcategories. This includes solutions with specialized, emerging, or cross-functional capabilities. These databases are designed to handle a variety of data types and structures, offering flexibility and scalability for diverse applications. They often provide unique features such as real-time data synchronization, end-to-end encryption, or support for immutable data storage, catering to specific needs that traditional databases may not address. These solutions are ideal for developers and organizations looking to implement advanced data management strategies without being confined to conventional database models.

To qualify for inclusion in the Other Non-Relational Databases category, a product must:

- Offer unique database functionalities that do not fit into existing NoSQL databases categories
- Provide specialized features such as real-time data processing, enhanced security measures, and support for complex data structures

### DatuBIM

Datumate, founded in 2011, is a construction technology (contech) company that offers a SaaS, cloud-based photogrammetry solution for stakeholders across the construction project lifecycle. Our product DatuBIM was launched in 2020 and is used by construction, engineering, and departments of transportation (DOTs) in the United States, Europe, and Middle East. DatuBIM is designed specifically for infrastructure construction and heavy civil projects. It focuses on three main areas:mapping and measuring sites; tracking and monitoring projects; and reporting on project progress as well as comprehensive quality control. How does DatuBIM help our clients? Below we have listed several use cases that illustrate the time and money savings DatuBIM provides. 1. Time Savings with DatuBIM’s Automated Engineering Report: Cross Section Volume Report in Highway Expansion Project. The challenge for a project engineer on a heavy civil highway project is accurately tracking the required quantity of aggregates for each base layer. DatuBIM's Cross Section Volume Report offers an efficient solution by comparing surface design files and a precise 3D model of the highway to generate cut fill volumes at each station on the alignment. Automated reporting allows for as needed calculations during the lifecycle of the project. Benefits include improved accuracy, increased efficiency, cost optimization, and enhanced project control. By utilizing DatuBIM's Cross Section Volume Report, project engineers can streamline the process of analyzing and quantifying earthwork volumes in civil engineering projects. 2. Scaling Data: Cloud Based Data Processing and Storage to Eliminate Data Silo. The challenge for a resident engineer is accessing drone photogrammetry data confined to a surveyor's desktop computer. Transitioning to DatuBIM's cloud-based photogrammetry solution solves this challenge by providing centralized data storage, real-time accessibility, collaborative environment, easy data sharing, and scalability. With DatuBIM, the resident engineer can overcome limitations in accessing and sharing data, ensuring seamless collaboration, enhanced productivity, and accessing time sensitive data as needed. 3. Dispute Resolution: Avoiding Costly Mediation with Subcontractors. The project manager faced a challenge when a subcontractor claimed to have completed the precast storm water drain installation before the deadline. Using DatuBIM's time-stamped images and 3D models, the project manager reviewed drone flights and discovered visible gaps and unfinished sections, contradicting the subcontractor's claim. Armed with this evidence, they engaged in a transparent conversation, and the subcontractor acknowledged the incomplete installation, resolving the dispute. DatuBIM's accurate and objective documentation showcased its effectiveness in conflict resolution, providing visual evidence and facilitating fair resolutions in construction projects. 4. Mass Haul Analysis: Avoiding Costly Hauling Fees. Grade Control Managers can optimize material distribution on construction sites by using DatuBIM's Volume Grid Heatmap Report. By integrating design models and drone data, DatuBIM generates a volume grid and heatmap report. Project managers can analyze the heatmap to identify optimal material placement, minimizing haulage distances and reducing costs. Regular flights enable ongoing adjustments. The report saves money by reducing haulage fees and maximizing efficiency. DatuBIM's Volume Grid Heatmap Report enables better decisions, resulting in significant cost and time savings. It enhances project efficiency, budget management, and overall construction operations. 5. Optimized Reporting: Relieve Month End Backlogs. DatuBIM simplifies end-of-the-month reporting for project managers dealing with multiple stockpiles in highway gores. The platform allows easy grouping of stockpile data into a single report, eliminating manual consolidation. Project managers can integrate information on stockpile locations, quantities, and changes, and download a comprehensive spreadsheet report. This streamlines the reporting process, saves time, and ensures data accuracy. DatuBIM's capability to consolidate stockpiles into a downloadable spreadsheet greatly enhances efficiency in end-of-the-month reporting tasks for project managers.
