There are many differences between correlational research and experimental research and we will discuss them in detail in this article. First, we will know about correlational research. Correlational Research Correlational research is a type of research which is non-experimental. The research is conducted on two variables and a correlation between them is checked. There are two reasons due to which this research is conducted. The first reason is that the researchers believe that statistical relationship is a causal one The second reason is that a correlational study is used in this research and no experiment is performed. The independent ... Read More
There are different types of computer languages which are used to make various types of software applications. In this article, we will talk about the difference between scripting and programming languages. Scripting Language Scripting language is a programming language in which a program is interpreted at runtime. The process of compiling is not performed in these languages. Scripting languages are used to establish communication between different programming languages. Types of Scripting Languages Scripting languages are of two types which include server side and client side. Server Side Scripts Server-side scripts are developed in such a way that they work at ...

Introduction To ensure both concurrency control and data integrity within database management systems (DBMS). Several locking mechanisms are employed — among them, one is being predicate locking. By utilizing this particular type of lock for protecting specified sections of the stored information from conflicting operations seeking simultaneous access. DBMS guarantees foolproof security measures. By designating a single transaction at a time for reading or modifying a given set of records predicate locking effectively eliminates inconsistencies that might occur due to concurrent access. Moreover. The lock is directly associated with specific predicates. Making it feasible for different subsets of ... Read More
