The Object Oriented Model The object-oriented(OO) model actually had its beginning in the 1970s‚ but it did not see significant commercial use until the 1990s. This sudden emergence came from the inability of then existing RDBMSs (Relational Database Management Systems) to deal with complex data types such as images‚ complex drawings‚ and adio-video files. The sudden explosion of the Internet and the World Wide Web created a sharp demand for mainstream delivery of complex data. An object is a

I. Column Oriented Database A column-oriented DBMS is a database management system (DBMS) that stores data tables as sections of columns of data rather than as rows of data. In comparison‚ most relational DBMSs store data in rows. This column-oriented DBMS has advantages for data warehouses‚ customer relationship management (CRM) systems‚ and library card catalogs‚ and other ad hoc inquiry systems where aggregates are computed over large numbers of similar data items. It is possible to achieve

I had a couple of the challenges I have faced in my project. One of the challenges I’ve faced was making the maze wide enough for the marble to roll with gravity. Another challenge I’ve faced was to make the maze thinner because if it is too wide‚ the velocity increases‚ but if the maze is a little bit thinner‚ the velocity

We encounter many craft- oriented objects day to day. I do not think I really thought about how objects were made and their value in life until I received this assignment. As I was thinking about all of the things that are craft- oriented‚ I especially thought about things at work and my home. I actually work at a dress shop and I’ve thought about how those dresses were made. Every dress company has a location where they make their dresses‚ like China. Each dress is handmade and takes many
