What is Screen Scraping?

Technology is continuously evolving around us at lightning speed. With immense innovations being applied daily universally. Scraping data from old software and applications has become complicated. It is not only time-consuming but a costly affair it is. To overcome data scraping needs from old or outdated applications we need another way! Screen Scraping significantly helps to shift legacy applications to containers and clouds. Hence, giving it an edge for falling under budget. To support and integrate legacy applications is undoubtedly a tough task, however, it is not impossible!


Fortunately, there is Screen Scraping which allows new and improved applications to easily interact with the legacy applications for data sharing.


What is Screen Scraping?


Screen Scraping is primarily termed as text data reading from your computer terminal screen. The latest form is referred to as a part of the program which helps mediate between the two applications and user interfaces. Screen scraping programs are specially made compatible with the outdated versions such that they can perform readability tasks very cleverly. Such legacy programs can work just fine and their data or form of logic can be derived for useful business operations.


How does it work?


Screen Scraping gets your data from where it is displayed in both data files and the database. The Screen is the core element within screen scraping. It directly scrapes the intended data as compared with the data of any other database or application.


For Example: Consider a daily life example from the banking sector, Here, the data is transferred from the legacy desktop CRM to CRM of another web-based solution. Such data is largely case sensitive and has to be completed with strict accuracy checks.


Since the legacy CRM does not allow API transfer of data. Therefore, API integrated methodology is not applicable. This might add up to the significant reason for you to test out Screen Scraping Today!


Screen Scraping proves a high-end solution to all data pull-off problems. It does not only scrapes data from the CRM via OCR but also stores it inaccessible databases ensuring 100% accuracy. Moreover, this can be done without the help of any modified application, a source code, or an API.


Screen Scraping Techniques


Screen Scraping Techniques allows pulling off data from an output display of any legacy application. The four techniques to use screen scraping with complete proficiency to your business advantage are as under:


Custom Mirror Driver


Custom Mirror Driver is a Display Driver, used commonly in remote desktop software programs and technical assistance technology. The custom mirror driver does its part by polling the screen changes for scraping updates. Also, it displays the operations and even extends them to gain a physical display device.


Using Standard APIs


Standard APIs are used to extract or scrape only typical desktop applications. Text from such applications can be extracted by employing a certain standard API to use. It can also be used to extract selected, cursor, or text information via sending certain window messages. To enable successful integration of business applications, APIs prove highly accessible. IA2, UIA are some commonly used APIs.


There are many such applications for API because of the compatibility challenges with APIs. In this case, it always proves best to consider which API works best with which application. A handful of applications such as LibreOffice, Microsoft Office, OpenOffice, have their APIs like Microsoft Office Interop UNO and more. It is comparatively easier to integrate such APIs which are compatible with both macros and web.


System APIs Interception


With Intercept APIs, you can easily command all operations on the software. Intercept APIs function calls to construct a set of functions like DrawText, TextOut, and other GDI+ methods in the case of the UI program. These direct target applications such as WinForms, WPF, MFC, or QT.


When intercept is performed with the assistance of the mentioned method, you can easily get the intended text, which is displayed upon the screen. However, every method has its limitations, the benefits come with a slight disadvantage that it has access to the undocumented APIs. Which becomes difficult from time to time as the complexity of data extraction increases. It lacks efficient data management and categorization.


Optical Character Recognition


OCR is also mentioned many times as Optical Character Reader instead of Optical character Recognition. It seeks electronic and mechanical image conversion of any handwritten or typed text into machine-encoded text. It is essential to keep in mind that OCR does not provide a complete accuracy rate. However, it can prove a remarkable easy source to scrape text compared with other methods which are not compatible with all applications out there.


Screen Scraping Tool


It is time to shed some light upon the screen scraping tools. Below are listed some of the top screen scraping tools which make screen scraping all-time hassle-free.
