Summary of CmdFreak
Several information systems and application software suites use a RDBMS (Relational Database Management System) as a persistence mechanism for their own data. The use of RDBMSs continues to expand.
Most RDBMSs are used as a background service for information systems and application software. However, such systems can also be accessed directly for data mining and faster business operations and maintenance.
An appropriate RDBMS can be chosen to match the characteristics of the target information system and application software. As a result, multiple RDBMSs are often used simultaneously in the same business operation and maintenance environment. However, operating multiple RDBMSs introduces the following issues:
- Different data reference software applications need to be provided, which may increase the learning cost.
- Data reference software needs to be installed on each client-side PC. The cost of introduction is therefore higher with a greater number of client PCs.
CmdFreak is a relational database viewer (data reference software) that provides solutions for the above problems.
- CmdFreak supports the major free RDBMS MySQL, PostgreSQL and MariaDB systems, providing a common user interface for these RDBMSs and enabling data reference as a common operation. This eliminates the need to learn different database viewer tools for multiple RDBMSs, which helps to reduce related learning costs.
- CmdFreak works as web application software, and comes with an all-in-one installer incorporating web server software. This eliminates the need for web server pre-configuration and the use of script language. As a result, the client-side installation cost is practically zero.
CmdFreak provides the following functions for database reference:
- List records/paging
- Table selection
- Table information reference
- Column filtering and sorting
- DBMS selection
