Benefits of databases Types of database system. Two types of database structure Databases typically have one of two basic forms: single-file or flat file database multi-file relational or structured database A flat file database stores data in a plain text file, with each line of text typically holding one record.

Types of relationships in a database Four types of relationships exist in relational database design: one to one - where one table record relates to another record in another table one to many - where one table record relates to multiple records in another table many to one - where more than one table record relates to another table record many to many - where multiple records relate to more than one record in another table These relations form functional dependencies within the database.

Four types of database management systems A relational database management system is one of four common types of systems you can use to manage your business data. The other three include: hierarchical database systems network database systems object-oriented database systems Hierarchical database model resembles a tree structure, similar to a folder architecture in your computer system.

NoSQL or non-relational databases A popular alternative to relational databases, NoSQL databases take a variety of forms and allow you to store and manipulate large amounts of unstructured and semi-structured data. Which database is right for you?

Not recommended when you do not have the budget or the expertise to operate a DBMS. Skip to content. What is DBMS?

Characteristics of Database Management System Here are the characteristics and properties of Database Management System: Provides security and removes redundancy Self-describing nature of a database system Insulation between programs and data abstraction Support of multiple views of the data Sharing of data and multiuser transaction processing Database Management Software allows entities and relations among them to form tables.

DBMS supports multi-user environment that allows users to access and manipulate data in parallel. Airlines For reservations and schedule information. Universities For student information, course registrations, colleges and grades. Telecommunication It helps to keep call records, monthly bills, maintaining balances, etc. Finance For storing information about stock, sales, and purchases of financial instruments like stocks and bonds. Manufacturing It is used for the management of supply chain and for tracking production of items.

Inventories status in warehouses. HR Management For information about employees, salaries, payroll, deduction, generation of paychecks, etc. Network Model The network database model allows each child to have multiple parents. Report a Bug. Previous Prev. Next Continue. Home Testing Expand child menu Expand.

Cloud compatibility. Business-oriented by nature and originally developed for the web, MySQL is supported by the most popular cloud providers. This makes MySQL even more attractive and gives businesses room for growth. Scalability challenges. MySQL was not built with scalability in mind, which is inherent in its code. So, if you expect one day your database will increase substantially, keep this limitation in mind or choose another DBMS option.

Partial open-source support. Why do you care? Because when you have completely open-source support, you expect many problem-specific implementations and community assistance.

Limited compliance with SQL standards. Structured Query Language has specific standards. The issues may appear when you have to shift to other databases, which is likely to happen when your business starts growing. Small web-based solutions. In combination with encrypted tablespaces, tables, and logs, it creates a robust protective layer for data.

Above that, MariaDB publishes the related releases on each security update, keeping the security patches totally transparent. Broad functionality. MariaDB has introduced a lot of new features in the last few years. For instance, GIS support suggests smooth coordinate storage and location data queries.

You also can extend its functionality with plugins that are available at MySQL via 3rd parties only. MariaDB is shipped with storage engines for NoSQL backend, legacy databases migration tools, sharding options, and many more. High performance. Extensive optimization features improve thread pool management and data processing. Thus, when rows from the table are deleted, the operating system immediately accesses the free space, eliminating gaps in the tablespace.

On top of that, the database management system suggests engine-independent table statistics. Still growing community.

Albeit MariaDB has a substantial open-source contribution, its community is yet to grow. Since this database management system was established not so long ago, the number of professionals is relatively small. Given currently existing differences between MariaDB Additionally, you get extended location data storage, higher performance, and improved scalability.

Oracle is a relational database management system created and run by the Oracle Corporation. Currently, it supports multiple data models like document, graph, relational, and key-value within the single database.

In its latest releases, it refocused on cloud computing. Oracle database engine licensing is fully proprietary, with both free and paid options available. Innovations for daily workflow. Starting with Oracle 12c release, when the software entered the hybrid cloud era, new cloud computing technologies have appeared on a regular basis.

With every new release, Oracle tries to keep up with the innovation pace while focusing on information security including active data guard, partitioning, improved backup, and recovery. Strong tech support and documentation. Oracle ensures decent customer support and provides comprehensive tech documentation across multiple resources. You may also expect some community support. Large capacity. Thanks to the recently released multi-tenancy feature, the database architecture now simplifies packing many databases and manages them smoothly.

In combination with in-memory data processing capabilities, it creates a strong engine for synchronous data processing. High cost. Though the Oracle database has free editions, they are very limited in terms of functionality.

Resource-consuming technology. Oracle database needs powerful infrastructure. Hard learning curve. Oracle database is not a system to start using right away. If you have a billion records to hold and manage — and sufficient budget to support it — Oracle hybrid cloud software is a good option to choose.

This database management system shares its popularity with MySQL. This is an object-relational DBMS where user-defined objects and table approaches are combined to build more complex data structures. Consequently, it can process any workload, for both single-machine products and complex applications. Great scalability. Considering that almost any custom software solution tends to grow, resulting in database extension, this particular option certainly supports business growth and development.

Support for custom data types. Additionally, it allows users to define their own data types. As your software business model may need different types of databases throughout its existence for better performance or application comprehensiveness, this option brings improved flexibility to the table.

Easily-integrated third-party tools. PostgreSQL database management system has the strong support of additional tools , both free and commercial. The scope of these includes extensions to improve many aspects. To make data comparison and synchronization more effective, consider using DB Data Difftective.

Open-source and community-driven support. Postgres is completely open-source and supported by its community, which strengthens it as a complete ecosystem. Additionally, developers can always expect free and prompt community assistance.

Inconsistent documentation. While PostgreSQL has a large community and provides strong support for its participants, the documentation still lacks consistency and completeness.

Lack of reporting and auditing instruments. A significant shortcoming of PostgreSQL is the absence of revising tools that would show the current condition of a database. You have to continuously check if something goes wrong. Due to complicated queries and a wide choice of custom interfaces accomplished with predefined functions, PostgreSQL is a perfect match for data analysis and warehousing.

All in one, it significantly accelerates the processing of vast amounts of data. This DBMS is popular with financial institutions and telecommunication systems. It copes well with effective storing, changing, and managing relational data. Variety of versions. Microsoft SQL Server provides a wide choice of different options with diverse functionalities. For instance, the Express edition with a free database offers entry-level tooling, the perfect match for learning and building desktop or small server data-driven applications.

The Developers option allows for building and testing applications including some enterprise functionalities, but without a production server license. For bigger projects, there are also Web, Standard, and Enterprise editions, with a varying extent of administrative capabilities and service levels.

End-to-end business data solution. The optional selection of components allows building ETL solutions, forming a knowledge base, and implementing data clearance. Also, it provides tools for overall data administration, online analytical processing, and data mining, additionally providing options for report and visualization generation. Rich documentation and community assistance. With Microsoft SQL Server aimed at comprehensive database maintenance, the full online documentation also reflects this concept.

The consequently structured guidelines, numerous whitepapers, and demos give a full picture of the MSSQL data system.

Also, Microsoft Premier provides access to dedicated Microsoft community support, which is an advantage when a DB engineer needs assistance. Cloud database support. The solutions allow shifting database administration to the cloud if your business software database becomes really overwhelming and hard to administer. Unclear and floating license conditions. Another issue is the ever-changing licensing process.

The pricing strategy itself is hard to understand and the elements included in a particular edition are floating, tending to shift from one to another.
