Nelson Data Systems has a passion for data in all its forms. We provide customers with personalized end-to-end solutions which organize disparate datasets into a secure, accessible structure.

We have found that data collection is often where the majority of the effort is focused, while data protection, integrity and accessibility can sometimes be overlooked or underestimated.

Without a reliable and efficient system in place, stakeholder confidence in the data plummets as a result of:

  • Multiple sources of the ‘truth’
  • Errors created during manual data manipulation
  • Insufficient or inefficient access for reporting/analysis purposes
  • Data entry errors which cannot be found and are therefore never resolved
  • Scalability issues

Nelson Data systems will work with you to design custom processes and infrastructure which meets these challenges.

Database design, development & administration

A well-designed and managed database is vital to a successful data strategy. Without a robust, efficient foundation, every subsequent piece of the puzzle will operate suboptimally.

NDS has decades of experience working with databases and we will work with you to design a secure, reliable structure which will bring order and integrity to your data.

Our business model allows us to be highly flexible and fluid when it comes to meeting the needs of a customer. We frequently work with databases hosted both within a customer's own network and in a range of cloud solutions. These are sometimes supplied by the customer, other times sourced and administered by us.

We have experience with many different database platforms and are comfortable with both closed (SQL Server, Oracle etc) and open-source (MySQL, PostgreSQL etc).

Data migration & quality

Businesses invest a huge amount of capital into the design and execution of data collection programmes. However, the precious results of these activities are frequently neglected.

Many organisations hold critical data in spreadsheets, small local databases and other similar data stores. The integrity and reliability of this data can be questionable and subject to accidental (or malicious) modification or deletion. We have discovered most businesses have difficulty comparing or merging data between these sets for analysis and reporting purposes.

We have many years of experience assisting customers to migrate this data into a robust structure, resulting in an enterprise-level database solution.

Part of this process is a joint-effort between ourselves and the customer to identify, review and correct erroneous and invalid data points. Often there are issues present in the data which are simply too difficult to detect outside of a rigorous migration process and were never previously discovered.

Once this process has been completed, your data will be of an extremely high quality and secure from further corruption or unintended alteration.

User Interface

Information can be secure and correct, but without an interface to interact with the data, it remains out of reach for the majority of end-users.

A good user interface may satisfy one or more requirements, including data entry, data review, quality assurance, access to analysis/reporting functionality and many more.

We have developed a wide variety of user interfaces from very simple data entry applications to complex, yet efficient, enterprise level solutions brimming with custom business logic as defined by the customer. We have the skills and capability to to undertake projects in both enterprise-level Microsoft technologies, such as .NET, but we are also comfortable utilising a variety of open source software and tools.

We work to design and create applications in a way that is intuitive, efficient and easy to use. We enjoy interacting with users, listening to how they work and devising workflow processes which enhance the user experience and exceed expectations.

Business Intelligence & Reporting

The actual worth of a dataset is directly proportional to the value it adds to the business. This value is exposed during analysis and reporting and in this way your data begins to justify the time and capital you have invested up until this point.

NDS has a deep understanding of this process and we work very hard to ensure this becomes a reality. Our aim is to develop efficient and innovative ways to view and analyse your data, whatever your unique requirements are.

We are experienced in the use of the Microsoft Excel BI toolset and SQL Server Reporting Services. Often we are asked to format and store data in a specific way to enable specialist users to analyse the data via external software, such as the statistical program 'R', or to provide access through a web application.

Usually the effort required to reach this apex is not apparent to the end-user, but with a polished, intuitive analysis and reporting solution, the true benefit of great data becomes obvious.

Department of Conservation

"NDS has been working with the Department of Conservation (DOC) to capture and validate some of their animal biodiversity monitoring data that has been held in many spreadsheets in the past. As this data is science based, significant effort has gone into the quality assurance and validation of the data. NDS has built data entry applications that have strong validation rules to ensure accurate data entry from field books (electronic field device capture is a future project). From humble beginnings, this SQL Server 2016 database now holds over 5.3 million individual actual data results, with a current programme of work that will add a further 1.5 million data results."
