Data Engineering, Modelling, & Migration
NDS has extensive knowledge in the design and development of solutions using a range of Database Management Systems, including SQL Server, Oracle, MySQL, MS Access, and others.
We are comfortable working with data in any form and of any type, from unstructured social survey data to normalised scientific data which must adhere to stringent protocols and standards.
We are frequently asked to design and develop automated data pipelines to feed data through a system, including cleansing, validation, and transformation into appropriate forms for storage and analysis.
Our services in this area include:
- General administration (system health, log checks, indexes/statistics, patching and upgrades, volume/storage monitoring, SQL agent management, backups and logs, up-time monitoring, instance configuration etc.)
- ETL (extraction, transformation, loading)
- Performance monitoring
- Business continuity planning and disaster recovery
- Database tuning
- Stored procedure and function creation
- Software installation and maintenance
- Security and authentication
- Data cleansing
- Data pipelines
- Data modelling
- Data and information management consultation
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.
NDS has assisted with the development of multiple enterprise level applications, both desktop and web, using combinations of the following technologies, libraries, and frameworks.
- DevExtreme Component Suite
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 to capture it.
Our team is experienced in the following technologies and tools:
- Microsoft Excel
- SQL Server Reporting Services
- Power BI
We are often asked to format and store data in a specific configuration to enable specialist users to analyse the data via external software, such as R, or to provide results for consumption through an API service.
Kelvin Sparks, CEO/Director
Kelvin has been working with databases and data since the mid 1980’s. A self-confessed “data nut”, Kelvin’s greatest satisfaction come from assisting clients to get
the maximum possible use from their data.
When not at work, Kelvin can be found enjoying the company of his wife, children and grandchildren (often around the BBQ).
Benjamin Foord, Operations Manager
Ben has been with NDS since early 2014 and has experience with SQL Server, SSRS, MS Access, and Microsoft Dynamics AX. He also helps to manage projects and write documentation as required.
He spends his spare time with his wife and three children, and also likes cycling, running, photography, and brewing.
Iurii Gerasimov, Senior Developer
Iurii has 15+ years professional experience working in information technology, software development lifecycles, enterprise application development and consulting.
He has been awarded a Masters degree in Computer Science and holds Microsoft Professional Certifications.
Iurii is usually busy working on a project, but in his spare time he enjoys hiking, reading, sports, and generally leading an active lifestyle.
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."
