Key Differences Between Microsoft SQL Server and Oracle

 

Before going into the key differences between Microsoft SQL Server and Oracle, an understanding of the two is relevant.

Microsoft SQL Server is a database product and helps users to SQL queries and execute them. It is a secure, reliable, and very stable database solution. SQL Server supports a wide range of transaction processing, analytics, and business intelligence applications.

Coming to Oracle SQL Server, Oracle Database is from Oracle Corporation and is aRDMS system built around the relational database framework. Data objects can be accessed by the users through the SQL language. Oracle is a fully scalable architecture and is one of the biggest vendors in the IT sector.



The key differences in Oracle SQL Server are as follows.

·        Oracle operates on a wide range of platforms while the SQL Server can be installed on the Microsoft Windows Server only.

·        Star query optimization is supported by Oracle while SQL Server does not provide query optimization.

·        Values do not change in Oracle before commit whereas values are changed in SQL Server even before commit. This is a critical difference in Oracle SQL Server.

·        During the transaction process, Oracle allows rollback. This is not so in SQL Server which does not allow rollback in the transaction process. 

·        Many “schemas” with the instance are supported by Oracle. However, SQL Server offers “schemas” within each database.

·        Database backups offered by Oracle are full, file-level, incremental and differential while SQL Server permits full, partial, and incremental backups only.

·        Finally, in Oracle SQL Server, Oracle uses both “after” and “before” triggers but SQL Server mostly uses “after” triggers only.

There are several areas also where Microsoft SQL Server scores over the Oracle database and vice versa.

The Use of ETL tool for Amazon Web Service (AWS)

Image
  Most organizations today require customized options to enable working with both structured and unstructured data so that the data from different sources can be integrated into one single database. There is a need to migrate databases to advanced platforms like AWS (Amazon Web Service) which is based in the cloud. This ensures that data warehouses, NoSQL databases, relational databases can migrate existing off-cloud databases and replicate concurrent changes while keeping data at source and target in sync. This process is facilitated by the use of an optimized and the right ETL tool for AWS . To migrate data from various sources to a single database and to streamline data management, the most used and common method is using the ETL tool as it guarantees quick data migration, data management, and data movement. The best ETL tool for AWS is ideal for cloud-based platforms like Amazon Web Service. Components of ETL tools Extract (E) – The required data is extracted from Hete...

Database Replication and the Types of Tools

Image
  Replication is the process where data is continually copied electronically from one database in a server or computer to another database in another server or location. This results in a distributed database where users can access necessary data without interfering in the work of others who are accessing the same data or server from the same or a different place. However, the replication process is not simple and can be precisely done only by following the right processes and using the most optimized tools. To make the process a success, the best database replication tool should be used. There are fundamentally three types of such tools and organizations should choose one that matches their need. Snapshot database replication tool – It is a simple process where a “snapshot” of the data in one server is taken and moved to a separate server or a database in the same server. After the first synchronization is completed, the tool refreshes the data in the published tables over f...

What is Change Data Capture for SQL Server

Image
  In today’s data-driven business environment, the overriding concern is data breaches. Organizations try to solve this issue by ramping up data security to protect historical data. Hence, the top database platforms like Microsoft SQL Server and Oracle database have introduced various solutions like timestamps, complex queries, triggers, and data audits. In 2005, SQL Server launched “after date”, “after delete”, and “after insert” features for SQL Server Change Data Capture ( CDC). But that only partially solved the issue. In 2008 SQL Server introduced a modified version of CDC that turned out to be more effective. CDC helps to track and capture all the changes that are made on the SQL Server database tables without extra programming. In the initial stages up to 2016, SQL Server Change Data Capture was active only in the Enterprise Edition but now, it is a universal feature in the SQL Server. CDC monitors the Insert, Update, and Delete operations in the table of a database. Al...
