    I like the availability group functionality. We are setting up more clusters using availability groups. The enterprise licensing or Software Assurance makes it a little bit cheaper as well. It is nice to have that read-only copy for reporting and everything else.

    There is a lot of functionality in Oracle Database. The reports and the GUI are good.Oracle Database is highly scalable.

  4. We use the basic features of MySQL. The interface that allows us to see the parameters of the server is good.MySQL has cross-platform support for multiple operating systems. The backups on a Linux machine can be restored on a Windows machine, and vice versa.
  5. The solution offers advanced features that the company was struggling to implement.The solution is easy to scale.
  6. I like that its true active-active. For example, if there are two instances within a cluster, we can take one of them down and there's no failover or switch over. There's no primary and secondary, it's true active-active. We can take one side down and we can upgrade that with new maintenance or a new version, obviously testing coexistence beforehand, without impacting the business.
  7. Teradata features high productivity and reliability because it has several redundancy options, so the system is always up and running. Teradata has good performance, the response times are very fast. Overall the solution is easy to use. When we do the transformation, we have all of our staging and aggregation data available.

What is a relational database management system (RDBMS)?

A relational database management system (RDBMS) is a software that collects, organizes, and retrieves stored data in a relational database. The RDBMS provides a user interface between the application and the database.

A relational database management system is a common database group that keeps data in tables so that it can be used in relation to other stored datasets. It has the capability of storing large amounts of data, so it is commonly used among various organizations.

Users are enabled to design a personalized database that can meet their individual analytic and reporting needs.

The purpose of relational database nanagement is to maintain various digital software system databases. Querying and maintaining aspects of the database is achieved by using SQL, (Structured Query Language) which is universally accepted by almost all relational database systems. An RDMBS manages, builds and deploys applications located on site or in the cloud. The digital space has a lot of competition and finding the best RDBMS requires IT experts to source the most comprehensive technology.

According to PeerSpot IT professionals, operational performance, (OLTP, DWH - ETL) security, support for developer APIs, and MDX support are among the most important RDMBS features. Scalability and modeling must be easy to use, and responsive vendor support is especially desirable. Data capacity, integration, and speed are integral to the needs of IT and DevOps.

Because IT managers have multiple needs within RDMBS, criteria for choosing a vendor requires the strictest data integrity and offer project specifications such as, “[a] distributed SQL database that has a flexible deployment model allowing the [team] to run the database on a single server machine, across machines in a data center or public cloud, and even on a global basis (across multiple data centers) without having to architect a new solution for each use case.”

PeerSpot IT and Devops managers are clear about how RDMBSs and their many features can function in an enterprise environment to be best leveraged in DevOps. There is a need for parallel distribution and parallel computing when evaluating performance.

One topic that is frequently discussed is, “transactional atomicity.” With all the moving parts in Relational Databases, the granular can become the springboard for success. These include loading and unloading data, meeting performance and recovery time objectives and adherence to standards.

PeerSpot developers have specific standards and would choose RDMBS based on whether the “DB comes with a mature BI stack.” RDMBS has many variables. PeerSpot users chose relational databases based on a number of criteria. PeerSpot’s offerings are complete and wide-ranging for the needs of IT and DevOps teams looking for agile excellence.

How does a relational database work?

A relational database works by storing data in multiple, related tables, using rows and columns. The logical data structures, which consist of the data tables, views, and indexes, are kept separate from the physical storage structure.

The physical separation means that administrators of the database can organize the physical data storage without changing the data of a logical structure. For example, retitling a database file does not change the name of the tables saved within it.

The relationships among data points are easily found, as each row in the table is a record with a unique identification called a key. Each column of the table holds elements of the data, and each record generally has a value for each element.

Effectively, the tables store data similar to an Excel spreadsheet. Rows are unique information, which uses their individual features, while columns are identifying attributes of the information. There can be millions of rows in a database. Columns are made up of one specific data type.

What are the types of databases?

There are nearly a dozen other kinds of databases. They include:

• Cloud databases
• Columnar databases
• Document databases
• Graph databases
• Hierarchical databases
• Key-value databases
• NoSQL databases,
• Object-oriented databases
• Time-series databases.
• Wide column databases

What are the advantages of relational databases?

Among the many advantages of a relational database, its simplistic model makes it a heavily desired option. No complex queries are required. Compared to other databases, a relational database offers a simpler model, free from complex structuring.

Unlike other databases, which require specific paths for accessing data, another huge advantage of a relational database is its easy access to stored data through any path. Even the ability to modify data is made quite simple.

For organizations with a large amount of data, the accuracy of data is essential. As a relational database uses an interrelated table, another benefit to this model is that stored data is not duplicated. This allows for the guarantee that all stored data is accurate.

Perhaps its biggest advantage is high security. The ability to make certain tables confidential makes relational databases a desired option, as one can give authorization to users to work on specific tables while keeping the rest of the information private. This provides an enormous advantage to companies with large amounts of data, where confidentiality is key.

What are the disadvantages of relational databases?

Though relational databases are free from complex structured data, with continuously increasing data, these databases may become complex, too, which can make the system more complicated. Since all data is organized using common characteristics, the more similar data that is inputted, the more complex the data environment can become.

In addition, the underlying cost involved in a relational database is its biggest disadvantage. A separate software must be set up, and an experienced technician is needed to service the system. For businesses working with smaller budgets, this can get costly.

Physical storage is the next biggest disadvantage, as a relational database demands an enormous mass of physical memory, considering it is made up of rows and columns.

Features of Relational Database Management Systems

What are some of the features of a relational database management system?

The main features include:

  • Data normalization - as multiple users have access to a database, one runs the risk of data duplication. Data normalization reduces this risk and diminishes the possibility of destructive redundancies appearing, which helps improve data integrity.
  • Data structuring - an RDBMS allows data to be stored in a concise and hierarchical way so that each data point can be arranged and stored systematically, and then accessed and retrieved easily.
  • Security protocols - security to all data is essential. Not only is the integrity of the database protected, but the data and records residing in it are protected as well by using data encryption.
  • User-defined integrity constraints - users can define integrity rules and constraints in order to prevent accidental damage to the database. The RDBMS allows each user to determine validation and integrity regulations.
  • Data backup - an essential feature, data backup can help your database recover any lost or corrupted data. This can protect your data against any accidental loss. Most RDBMSs can protect against logical and physical data backup.
