SQL and Java: a comparison

SQL and Java are both programming languages in great demand in today's job market. Both hold under increased task load and despite changes to their application: one may execute 13 lines in either language, yet both will complete tasks as efficiently as if there were only one line. Both possess releases subject to use, study, change, and distribution by anyone and for any means, making them accessible to all potential users and thus highly desirable for said users: there is no pay barrier for anyone wishing to employ SQL or Java. Also, their form is similar: where databases are in SQL, procedures are in Java; where arguments are placed after procedures in Java, arguments succeed databases in SQL. Both SQL and Java are thus similar in their appearances and availability to the public.


Similarities end there, however. First and foremost, Java is a general programming language: it communicates with the computer in machine language, i.e. 0s and 1s, thus permitting a greater range of activities within a computer. SQL, by contrast, queries the computer for databases it then manipulates as users will: it is a data query language, and thus limited in functionality. SQL is thereby standard for querying, manipulating, managing and otherwise operating on databases whose data can be arranged into tables and have some common idea. Java is not standard for this purpose. Furthermore, though Java can perform functions similar to SQL's, it Is more tedious to do so than with SQL. This is one reason why Java is regarded as harder to learn than SQL. Another reason why Java is considered harder to learn is its data and anything possessing a state, behavior, and procedure: all new data must be assigned initial values. SQL lacks such a requirement and anything having a state and behavior lacks a procedure in SQL. This allocates ease of use to SQL users compared to Java, though Java thereby provides users with more control of data. Following ease of use, SQL adheres to English syntax; Java does so to a lesser degree. Given differences between the two, SQL does less in exchange for accessibility for novices; Java does more in exchange for a steeper learning curve.
