Many programming languages like Java have strict type checking. when I am trying to parse date while loading or trying doing this after loading using --pandas.to_datetime-- its taking too long to convert it since rows are in 100s of millions. The object is a complex data type that allows you to store collections of data. Note that R also has a built-in mode() function that will serve the same purpose with the one exception in that it will not distinguish integers from doubles. For brevity and clarity in the reference documentation, rather than detailing each data type in the main documentation, the data types are fully defined here. This information is vital to the interpreter. A property key (name) is always a string, but the value can be any data type, like strings, numbers, booleans, or complex data types like arrays, function and other objects. The data types can be divided into value type and reference type. The default value of Object is Nothing(a null reference). Object-Oriented Programming is especially suited for building reusable components and complex applications. Database Object: A database object in a relational database is a data structure used to either store or reference data.
