TOP JavaScript TreeGrid libraries in 2020-2021

The article will cover one of the most complex interface elements for web applications: ​JavaScript TreeGrid​. It will be of interest to front-end developers and novice JavaScript programmers developing business applications and solutions for working with rich data.

From this material, you will learn about ready-made TreeGrid solutions, their purpose, and application methods. At the end of the article, we will look at the TOP 5 TreeTable web widgets that you can freely download and use in your work.

Using ready-made JavaScript components significantly speeds up the development process and allows you to avoid unwanted errors. We will look at the products of Webix.com, Treegrid.com, jQuery.com, DHTMLX.com, and Sencha.com.

What is it?

Let’s start by defining what a TreeGrid or TreeTable is. It is a way of arranging table data in the form of a list of hierarchical tables. Traditionally, TreeGrid allows developers to create tree-like lists where entire tables are used as “branches.”

The TreeTable component has appeared as a logical response to the complexity of working with the UI trees. On another one hand, TreeTable is a classic DataGrid that allows you to conveniently present information in the form of a table. On the other hand, it performs tree-like hierarchical grouping of table data in the same way as the Tree widget.

Do not confuse the TreeTable component with the grouping of rows and columns used in DataGrid.

Grouping columns

This mechanism is available in some advanced UI widgets, such as ​SpreadSheet JS​, where rows and columns are grouped in an Excel manner. But TreeTable is a more complex solution, as it groups not only separate data but also entire arrays of information. In addition to that, it displays table data in a hierarchical subordination and control elements to view this structure.

Application areas of TreeTable

Such interface solutions are in demand in the areas related to:

  • Big-Data;
  • Analytical systems;
  • Financial statistics;

Any industry or business task that contains rich data can use this solution. A key sign that analysts and developers should pay their attention to the TreeTable components is the so-called “data rhythm.”

When data is grouped, for example, by date, in this case, there is a prerequisite for working with three-dimensional arrays of information, which is quite challenging to implement in practice, but it is possible using TreeGrid.

Example:

A good illustration of the demand for TreeTable in applied tasks with big data is the speech of the developer and former Google employee ​Dan Dascalescu​. At a conference in San Francisco, he presented a prototype analytical system, the core of which was TreeGrid.

The development team set an ambitious goal of creating tools for working with complex structured data. The use of the TreeGrid component allowed them to solve the main tasks and complete the project in a shorter period. The full version of the speech can be found at this link​.

Advantages and disadvantages of the TreeTable/TreeGrid UI component

The advantages include:

The possibility to visualize three-dimensional data arrays on a single screen, without having to switch to nested tabs.

Here we note the apparent disadvantages of this approach:

  • The user may get lost in a large number of nested tables. You can avoid this by using navigation and table management elements, such as collapsing/ expanding all data branches.
  • A large amount of data uploaded to the browser loads the client part of the system significantly and can lead to errors due to physical limitations (the maximum size of the web page, the amount of RAM).
  • Complex tables with a large number of rows and columns will be rendered slowly in the browser, so you should choose solutions optimized for rendering speed as much as possible.

The possibility to quickly navigate through large amounts of data without using filters and search queries. TreeTable is a powerful analytical tool in the hands of an experienced user.

Disadvantages that analysts mention:

  • The complexity of working with “end-to-end data,” in cases when TreeTable can combine tables with different structures.
  • It is not possible to build a pivot table.

The opportunity to combine data of different formats in the same table when the nested table has a structure different from the “parent” table.

4 Ways to Reduce the Risk of Human Error When Entering Data

Data entry is a vital part of many businesses, but it is also one of the most error-prone processes in any field. Human errors can lead to costly mistakes, negatively impacting business operations. That’s why it is essential to implement systems and procedures that reduce the risk of human errors during data entry processes. This article will discuss four strategies you can use to minimize the risk of human errors during data entry processes.

1. Utilizing Automation Tools

Automation tools are essential for minimizing the risks associated with manual data entry. Automated software and systems eliminate the potential for human error by automatically transferring data from one system to another without any manual input. These automated tools also reduce the amount of time spent on mundane tasks such as data entry, meaning that more time can be invested in higher-level tasks which require more input and analysis.

Automation tools are particularly useful for businesses with large volumes of data to process or complex datasets requiring numerous calculations. In addition, they allow users to access the same data from multiple applications and devices, meaning that data can be shared easily between different systems.

Furthermore, automation tools allow businesses to incorporate customization into their data processing. This means that users can tailor the system to their specific needs and set up automated notifications and alerts when specific system parameters have been met.

2. Verifying Data

It’s essential to verify all data before entering a system or database. You can do this manually by having someone review the data for accuracy or through automated systems that check the data against existing records. Verifying data ensures that only accurate information is entered into a system, thus reducing the risk of human error during data entry processes.

Once the data is verified, you can use it to create reports and insights. For example, if a company has sales data entered into a system with no errors, it can quickly generate detailed financial reports with accurate information. The same goes for any other type of data – verifying it beforehand ensures that the results are accurate and reliable.

In addition to accuracy, verifying data also helps protect against malicious data manipulation. By ensuring that all entries are correct, organizations can reduce the risk of fraudulent activities such as identity theft or financial fraud. Furthermore, verifying data helps maintain security standards across different systems and databases by providing an additional layer of protection against potential cyber-attacks.

Utilizing Automation Tools

3. Providing Training

Employees must be adequately trained to enter data into a system or database. Regular training sessions should cover the procedures and guidelines, as well as discuss best practices for entering data accurately and efficiently. This will reduce the chances of employees making mistakes when entering data into systems.

Furthermore, it is crucial to provide employees with ongoing training and support. This way, they can stay up-to-date with the latest developments in data entry techniques and ensure that their skills are not becoming outdated. Training should also include problem-solving scenarios so employees can practice their decision-making skills practically. Additionally, it is vital to provide feedback and reviews after training sessions for employees to know if they are following the correct procedures.

Other aspects of providing training that should be considered include the need for adequate resources, such as having a well-equipped computer room or access to appropriate software. It is also essential to ensure that all employees have the same level of understanding about data entry and databases so that everyone can contribute to the process.

4. Outsourcing

If manual data entry is necessary, it may be best to outsource the task. By outsourcing processes to professional data entry services, businesses can reduce their risk of human errors and ensure that accurate data is entered into their systems.

Outsourcing data entry can also offer cost savings for businesses. By utilizing a third-party data entry service, companies can avoid the expense of hiring additional staff or providing training to existing employees to do the work. In fact, statistics show that outsourcing data entry can reduce costs by up to 70%. Additionally, external data entry services can often complete work faster than in-house teams.

To outsource data entry properly, it is vital to ensure the service provider is reliable, experienced, and offers the right level of quality control. Companies should carefully research potential providers and select a partner that fits their needs. Once an outsourcing partner has been selected, businesses can test their services with small tasks to assess quality and accuracy.

Final Words

Data entry errors can have severe consequences for businesses, and taking steps to minimize the risk of human errors occurring during data entry processes is essential. These are all strategies that can help reduce the chances of mistakes being made during the data entry processes. Implementing these strategies can help ensure that your business’s information is accurate and up-to-date at all times.
