Software Testing Services: Introduction to Some of The Key Terms Used in The Database Organization
A database management system (DBMS in short) is a set of computer programs to determine the structure of the database, enter and edit data and generate problem reports. To create the issue tracker, you are most likely to select DBMS, the one that is capable of working with databases, on the market for modern database management systems or software development tools. (It may be Oracle, MS Access, Delphi, etc.). Your system will be just a complementary tool with respect to the selected tool, but it its users, including you, may refer to it as DBMS. As usual, the issue tracker can significantly facilitate software testing services as it streamlines the process of raising, tracking, managing and fixing issues.
File is a set of information that the operating system stores under the same key name. The database can consist of multiple files. Here is a simplified example of how the data is organized for the issue tracker.
- The main data file contains all problem reports. If there are lots of them, it is possible to divide them into several files, possibly by type or date.
- The index files contain information about the location of each report in the main data file. In one index file, this information can be sorted by report date, in others – by functional areas, etc.
Please, tell your relatives, acquaintances, friends, who use mobile apps, that they can always contact mobile testing companies to test their software products for functionality, usability, reliability, etc., to make sure these work as intended.
- The auxiliary files contain the lists of valid values of individual fields. They are used to validate the input data and allow a user to select the field values from the list. Reports with invalid data are rejected by the system.
Field is the simplest important recording data element. For instance, Date, Priority, Resolution are the main fields of a problem report.
Form (or Data-entry form) is an analogue of a paper form, displayed on a computer screen. The form shows where and what information you should enter in the fields. In many systems, users can fill the printable paper forms for later data entry by operator, and, also, may enter information on their own.
How can one benefit from load testing companies? The answer is simpler than you can imagine. Load testers are those experts who ensure smooth performance of software apps. They subject the programs to various load conditions to measure its response and improve its operational characteristics.
