Ask the right questions to secure the right FoxPro talent among an increasingly shrinking pool of talent.
FoxPro is a data-centric procedural programming language developed by Fox Software in the mid-1980s, later acquired by Microsoft in 1992. It is renowned for its database management capabilities, particularly for the DOS and Windows platforms. The language is object-oriented and provides powerful data handling functions, making it ideal for business applications. FoxPro was eventually replaced by Visual FoxPro in 2004, which was then discontinued by Microsoft in 2007. Despite its discontinuation, it remains popular among developers due to its robustness and efficiency in managing large databases.
The next 20 minutes of the interview should attempt to focus more specifically on the development questions used, and the level of depth and skill the engineer possesses.
FoxPro supports three types of indexes: Regular index, Compound index, and Candidate index.
FoxPro provides ON ERROR command to handle errors. You can specify a command or a procedure that will be executed when an error occurs.
A Form is a graphical interface used for interaction with the user while a Report is a formatted and organized presentation of data.
FoxPro supports various data types such as Character, Numeric, Float, Date, Logical, Memo, General, and Binary.
You can create a new database in FoxPro using the CREATE DATABASE command followed by the name of the database.
Effective communication is important in any role, but especially so in development where they may need to explain complex concepts to non-technical colleagues.
The tech field is constantly evolving, so it's crucial that the candidate is adaptable and can pick up new skills as needed.
Software development often requires collaboration, so it's important that the candidate can work well in a team.
FoxPro is a database management system, so experience in this area is a key indicator of potential success in the role.
Problem-solving skills are important for developers as they will often need to troubleshoot and fix issues.
This is crucial as the candidate needs to be proficient in FoxPro to be able to perform the job effectively.
The next 20 minutes of the interview should attempt to focus more specifically on the development questions used, and the level of depth and skill the engineer possesses.
Performance in FoxPro can be optimized by using indexes effectively, optimizing SQL queries, and using the SET OPTIMIZE command.
A View is a virtual table based on the result-set of an SQL statement. A Cursor is a temporary work area created in the system memory when a SQL statement is executed.
Key features of FoxPro include support for SQL queries, powerful data manipulation capabilities, support for various data types, and a robust programming language.
You can create a relational database in FoxPro by defining relationships between tables using the SET RELATION command.
A Procedure is a set of commands that performs a specific task and does not return a value. A Function also performs a specific task but it returns a value.
At this point, a skilled FoxPro engineer should have demonstrated proficiency in FoxPro development, a strong understanding of relational database concepts, and problem-solving abilities. Red flags would include a lack of specific examples of past work, inability to discuss complex concepts, or unfamiliarity with latest FoxPro versions.

FoxPro is a file-server database management system that supports both procedural and object-oriented programming. It differs from other DBMS in its data handling capabilities, programming flexibility, and ease of integration with other software.
Advanced features of FoxPro include support for Object-Oriented Programming, ability to create and manipulate databases using SQL, and support for creating standalone applications.
Transactions in FoxPro can be handled using the BEGIN TRANSACTION, END TRANSACTION, and ROLLBACK commands.
A Table is a collection of related data held in a structured format within a database. A Database is an organized collection of data, generally stored and accessed electronically.
FoxPro supports two types of locks: Record lock and File lock.
