A database object in a relational database is a data structure used to either store or reference data. The most common object that people interact with is the table. Other objects are indexes, stored procedures, sequences, views and many more. When a database object is created, a new object type cannot be created because all the various object types created are restricted by the very nature, or source code, of the relational database model being used, such as Oracle, SQL Server or Access.

that can be easily delineated into respective tables to make Database Management Systems capable of utilizing the data effectively. With normalization, information can be confidently accurate in any system and it is to a business’ loss if the fundamentals of normalization are ignored. So what does Normalization look like? There are four levels called first, second, third and fourth normal forms. First Normal (1NF) requires the database to have no repeating groups and must identify all the key…
Data integrity ensures that data is ultimately accurate. This is important when trying to analyze data that is stored in the database or data warehouse. Inaccurate data will lead to false results in reporting and analytics that will affect any business decisions that need to be made. When dealing with data integrity, having the full or complete set of data is a necessity. If only half or some of the data is entered than it cannot be considered accurate. There are several ways to ensure that data…
