What Does the SAP Database Mean? 

Systems, Applications and Products (SAP) Databases can be defined as an organised collection of structured data that helps facilitate OnLine Analytical Processing (OLAP) and OnLine Transition Processing (OLTP) for companies from different sectors. These companies belong to various sectors, such as banking, e-commerce, manufacturing, technology and healthcare. These Databases ensure that the data they store live up to the following features: 

1) Accurate: This feature of the data ensures that the data does not have many errors and has no duplicate versions.   

2) Complete: This feature of the data ensures that the data has no missing values.  

3) Relevant: This feature of the data ensures that the data used for analysis is completely updated and relevant to the necessary context.  

4) Conformant: This feature of the data ensures that the data follows a given set of rules and standardised formats that are defined as part of an organisation’s Data Management strategy process. 

5) Consistent: This feature of the data ensures the uniformity and consistency of data as it is transferred between systems and applications.    

6) Secure: This feature of the data ensures that it is secure from unauthorised attacks, data breaches or corruption.

What are the Different Types of SAP Databases?

There are several types of SAP Databases, all of which we will explore in detail below:

1) Network Database 

A Network Database consists of multiple member files or records linked to multiple owner files and vice versa. A Network Database provides multiple owners with various data access paths. The Database can be imagined as an upside-down tree, where the member information represents the branches leading to the owner at the bottom – and every fragment of data is eventually connected to the main data.   

Network Databases allow more natural modelling of relationships between records and entities. It is also more flexible and accessible, which results in faster search, navigation and access to data. An example of a Network Database is SAP HANA, which consists of components that facilitate system communication with the help of Networking channels. 

2) Open-source Database 

An Open-source Database has a code that can be accessed publicly and is free to download, re-use and modify. This Database stores important information that organisations control. Users can use the Database to create their systems in accordance with their business requirements and modify the source code according to their preferences.   

Users of Open-source Databases do not require any payment for using the code, unlike Commercial Databases, where users pay to use larger datasets or access additional features. These Databases are cost-effective and flexible to use. An example of such an Open-source Database is SAP MaxDB.   

3) Object-oriented Database 

Object-oriented Database Management Systems (OODBMS) make code easier to manage as they help integrate Database functionality into Object-oriented Programming languages. Such Object-oriented Databases incorporate Relational Database principles. An OODBMS is known to use the following: 

1) Objects: Objects are building blocks of classes with either built-in or user-defined types. 

2) Class: A class determines the behaviour of an object. 

3) Methods: The methods of a class determine its behaviour. 

4) Pointer: A pointer helps access elements of an object Database and establish relationships among objects.  

Using Object-oriented Databases has several advantages. The advantages include transparency, easy retrieval, seamless integration and persistent storage. Users are allowed to store all the properties of data objects in the Database, and the Database continues to store them after the program terminates. Upon restarting the program, the Database can retrieve an object with the specified properties. This facilitates the storage and retrieval of complex data objects transparently.    

4) Cloud Database 

A Cloud Database can be defined as a Database hosted on a Cloud server which can be accessed through a web interface or Applicating Programming Interface (API). Much like traditional Databases, these Cloud Databases provide several functionalities.

However, they facilitate secure data storage without the organisation investing in expensive hardware. Cloud Databases are known to support Relational Databases such as Structure Query Language (SQL) and NoSQL Databases such as MongoDB. Their common features include the following: 

1) Scalability: This feature helps businesses easily manage large volumes of data without affecting the overall performance.   

2) Elasticity: This feature means businesses can increase or decrease the number of data nodes per their specific requirement. 

3) Security: This feature assures that the data stored in the Cloud is safe from any possible theft or unauthorised data breaches. 

4) Redundancy: This feature means businesses can ensure their data despite server failures due to regular backups. 

5) Manageability: This final feature means that IT teams can conveniently perform several administrative operations on the Database. 

5) NoSQL Databases 

NoSQL refers to all the Database technologies which do not use Simple Query Languages as the primary language while accessing data. These kinds of Databases are different from Relational Databases, as they  do not require a predefined schema - a feature that makes them great for semi structured or unstructured data. These Databases are often referred to as Non-relational Databases. Some of its features include: 

1) Modifiability: Programmers can modify the NoSQL Database in real time. 

2) Integrity: Modifying data in this Database does not affect the applications. 

3) Versatility: This Database can benefit from technologies like Apache Cassandra, MongoDB, CouchDB, and CouchBase.

What are Some Examples of SAP Databases? 

Now that we have discussed what an SAP Database is as well as the types of SAP Databases, we will look at a few examples of SAP Databases now. 

1) SAP HANA 

SAP High-Performance Analytic Appliance (HANA) is a multi-model Database that facilitates using multiple data models using a single back-end. As with traditional Databases, an SAP HANA Database stores data in its memory rather than on a disk, which facilitates faster data access than Disk or Solid-State Drives (SSD).

The Database supports the search, analytics and integration of structured and unstructured data. It also helps develop smart, insight-driven applications through real-time data, in-memory computing and machine learning. One can access these features both on the Cloud and on-premises.   

2) SAP IQ 

SAP Intelligent Query (IQ) is a column-based, Relational Database system that facilitates Business Intelligence (BI), data warehousing and data marts. The two principal components of SAP IQ are clients and servers, both of which provide their own features to the Database. The client components provide connectivity, SQL command pursuing, authentication, monitoring and administration via the web. The server components provide features such as column stores, query engines, parallel data loading engines, Database encryption, authorisation and scalability. 

3) SAP ASE 

SAP Adaptive Server Enterprise (ASE) is a Relational Database server known to handle large volumes of data and users simultaneously. This feature of the SAP ASE Database ensures reliability, accessibility and performance across multiple industries. It also facilitates the processing of mission-critical transactions while maintaining high levels of performance and availability.

These Databases also possess flexible SQL systems that decrease risk and improve agility. The SAP ASE is also resource-efficient, meaning that it helps organisations lower their operational costs.

4) Oracle Runtime Database 

Oracle Runtime Database is multi-platform document store which allows you to access data regardless of your device type and its Operating System (OS). This allows clients to work using different programming languages like Android, JavaScript, and iOS while using an instance of a Realtime Database. 

Oracle Runtime Database is available for both mobile and website-based access. Additionally, it offers the benefit of being automatically updated with the latest data control features. 

5) SAP MaxDB 

SAP MaxDB Database is known for the consistent structure of its data. This is possible due to the application data and the metadata within the metadata having a unique name, allowing for consistent formatting. 

6) Microsoft SQL Server 

Microsoft SQL Server is one of the leading figures in the domain of Databases It is a Relational Database Management tool which is capable of supporting multiple applications. The usage of this server includes transaction, processing, and analysis. 

7) IBM Db2 

IBM Db2 is a collection of products, which is frequently used for Database Management. Db2 is one of the most popular AI- powered tools in this Database, capable of helping with both structured and unstructured Data Management. The Db2 range of tolls simplify the data handling process, by allowing you to take advantage of AI.
