7 Common Challenges That Database Developers Can Solve

What problems can database developers help with?

Database developers play a vital role in helping with the progression of business-critical systems, however there are also several challenges which can be resolved with the injection of a development team's knowledge and expertise. SQL Server Developer - Robin, has highlighted several common challenges which WellData is resolving for companies on a regular basis.

System Complexity

Over time the complexity of databases can increase and lead users to feel as though they no longer have an understanding of the database and its environment. 

Database developers can resolve database complexity through a combination of best practices, design principles, and the use of appropriate tools and technologies. WellData's team of database develops look at the following areas;

• Normalisation
• Data Modeling
• Indexing
• Use of Views
• Stored Procedures and Functions
• Consistent Naming Conventions
• Version Control
• Testing and Quality Assurance
• Security
• Scalability
• Object Relational Mapping
• Maintenance

Limitations and Restrictions

Poor decisions surrounding the database and its enviroment may lead to limitations and restrictions for users in the future. When considering transformation, users will face issues and be unable to resolve the restrictions that are in place without abandoning the system and starting again, so often they disregard modernisation plans due to lack of experience. 

A knowledgeable database developer can fill in the gaps and give users the confidence they need to proceed with system updates and upgrades, by removing responsibility.

Documentation

Often, those who create or update databases and data resources do not realise the importance of documentation. So, when sytems are inherited by new users, they are unable to carry out tasks without risking performance issues. 

The role of a database developer involves documenting system architecture and maintaining documentation with all information regarding any changes that are made.

System Inheritance

And, when staff members do leave, systems are passed onto other employees. But, those who inherit the databases may not have the relevent knowledge or understanding to maintain the processes. Documentation can assist with this, but a lack of knowlege will increase risk of human error.

Employing a database developer can alleviate risks, as they will have the knowledge and experience to carry out processes in line with best practices and if they occur, resolve issues quickly. 

Performance Optimisation

Databases grow rather organically. Old data or system procedures can bloat the environment and cause poor performance, complexity or other unexpected behaviours. Developers are equipped with the knowledge to identify performance related issues and remove unnecessary elements. 

Compliance

Regulations are constantly updating and if companies are in breach, there can be horrific financial implications. Remaining aware of rules and regulations is an important and ongoing activity which many do not maintain. WellData's development team have tools in place to identify potential updates to rules and alert companies of changes before making any updates required. 

Skills and Knowledge

One of the most common challenges is reluctance to change. Databases and systems have matured so much so that many companies are working with technologies which are 10+ years old and the existing business requirements no longer suit the original specifications. Businesses are unable to take advantage of the latest technologies or unwilling to update their practices to meet industry standards. An external team can influence more willingness and educate users on the benefits of taking a new approach. 

Similarly, if users have become so focused on one environment, they do not have the skills or knowledge to identify new opportunities which may improve the businesses' situation and therefore, a fresh perspective on database development can open up many new doors.
