Click on the arrows to vote for the correct answer
A. B. C. D.B.
Embedded database 4GLsare depend on self-contained database management systems.
These characteristics often makes them more user-friendly but also may lead to applications that are not integrated well with other product applications.
Example includes FOCUS, RAMIS II and NOMAD 2
For CISA exam you should know below mentioned types of 4GLs Query and report generator " These specialize language can extract and produce reports.
Recently more powerful language has been produced that can access database records, produce complex on-line output and be developed in an almost natural language.

Relational database 4GLs " These high level language products are usually an optional feature on vendor's DBMS product line.
These allow the application developer to make better use of DBMS product, but they often are not end-user-oriented.
Example include SQL+ MANTIS and NATURAL.
Application generators " These development tools generate lower level programming languages(3GL) such as COBOL and.
C.
The application can be further tailored and customized.
Data processing development personnel, not end user, use application generators.
The following were incorrect answers: Query and report generator " These specialize language can extract and produce reports.

The fourth generation language (4GL) is a programming language that is used to create high-level, self-contained programs for specific business applications. These languages are designed to be easier to use than traditional programming languages, as they typically rely on pre-built libraries and tools for common programming tasks.
The answer to the question is B. Embedded database 4GLs.
Embedded database 4GLs are 4GLs that are specifically designed to work with self-contained database management systems. These systems typically include built-in support for managing data storage, indexing, and retrieval, as well as query and reporting capabilities. Examples of embedded database 4GLs include Microsoft Access, FileMaker, and dBASE.
Query and report generators, on the other hand, are tools that allow users to generate customized reports and queries based on data stored in a database. These tools do not necessarily rely on a self-contained database management system, but can be used with a variety of different database systems.
Relational database 4GLs are 4GLs that are specifically designed to work with relational databases, which are databases that organize data into one or more tables with a predefined relationship between them. Examples of relational database 4GLs include SQL and Oracle PL/SQL.
Application generators are tools that allow users to create customized software applications without having to write any code. These tools typically include pre-built modules and libraries for common programming tasks, and may rely on a variety of different programming languages and database systems.
In summary, the correct answer to the question is B. Embedded database 4GLs, which are 4GLs that rely on self-contained database management systems.
