DATETIME and TIMESTAMP are the data types in MySQL. Both of them can store the values that include data and time part. The significant difference between these two data types is the range of values they accept. The DATETIME data type supports a larger range as compared to TIMESTAMP. As DATETIME supports a larger range, the size of this data type is even bigger than that of TIMESTAMP. In this section, we will explore these data types in detail. We will also identify the maximum differences … [Read more...]

The file system and DBMS offer you a way to store information. But there are many differences between these two methods. The file-based system is a conventional method of storing the data, whereas DBMS is an advanced method. In the file-based system, information is stored in separate files, which leads to redundancy and inconsistency. However, in DBMS, all the data files are integrated into one system, which reduces the chances of redundancy and inconsistency. If we talk of the file-based … [Read more...]

The basic difference between a server and a database is that server is a computer program that runs to provide services to other computer programs or devices. On the other hand, the database is an application that stores data in an organized form and can be retrieved by the user with the help of a query. In the section ahead, we will be discussing the differences between server and database. Content: Server Vs Database Comparison Chart What is Server? What is Server Used for? … [Read more...]

Backup and Recovery are terms related to data protection. An efficient backup and recovery schemes are crucial for any organization for protecting the valuable data of its organization. However, backup and recovery are different concepts where a backup is storing a copy of the entire data of the database or database onto storage devices. Conversely, recovery is the technique of restoring the lost data from the storage mediums which have been backed up. Content: Backup Vs Recovery … [Read more...]

SQL and T-SQL are the query languages used to manipulate the database and are an important part of the DBMS. The prior difference between the SQL and T-SQL is that the SQL is non-procedural while T-SQL is a procedural language. T-SQL is an extension to SQL, developed by Sybase and Microsoft. It has additional features to the SQL like transaction control, row processing, exception and error handling and declared variables. However, all these SQL server interactions are carried out by sending … [Read more...]

The descriptive and predictive data mining techniques are used in data mining to mine the types of patterns. The descriptive analysis is used to mine data and provide the latest information on past or recent events. On the other hand, the predictive analysis provides answers of the future queries that move across using historical data as the chief principle for decisions. Data mining tasks can be descriptive, predictive and prescriptive. Here we are just discussing the two of them descriptive … [Read more...]

In SQL, the DCL commands are used for assigning the different authorizations to the user, these type of authorizations is known as privilege. Grant and Revoke commands are the DCL commands. The GRANT command is used for conferring the authorization to the users whereas REVOKE command is used for withdrawing the authorization. Select, insert, update and delete are some of the privileges that are included in SQL standards. Content: Grant Vs Revoke Comparison Chart Definition Key … [Read more...]

Mirroring and Replication are the terms somehow related to copying of data in a DBMS. The prior difference between mirroring and replication is that mirroring refers to copy a database to another location whereas replication includes the copy of data and database objects from one database to another database. Both mirroring and replication are advantageous and increases the availability and performance of the data or database. Content: Mirroring Vs Replication Comparison Chart … [Read more...]

Clustered and Non-clustered index are the types of single-level ordering index where clustered index determines how the data is stored in the rows of a table. On the other hand, the non-clustered index stores the data at a single place and the indexes are stored at another place. Additionally, each table can have only one clustered index. As against, In case of a non-clustered index, a table can have multiple non-clustered indices. The indices are essentially required for the efficient … [Read more...]

We have already studied different types of keys used in database and schema in the previous articles namely Difference Between Primary key and Foreign Key. In this article, we are distinguishing Primary key and Unique key. Both primary key and the unique key is used to identify a tuple uniquely and enforces uniqueness in a column or combination of a column. The essential difference between primary key and unique key is that primary key does not accept NULL values whereas NULL values are … [Read more...]
