An in-memory database is a record that employs Random Access Memory (RAM) as main memory rather than the use of disk. Database Management System is organised to perform totally on disk or entirely in-memory or both collectively.
An in memory database is considerably faster or quicker as compared to the conventional databases. The reason of the faster speed is due to use of Random Access Memory. This is the main memory which is quicker to recover or retrieve data as compared to a drive of the physical disk. The use of RAM decreases the total amount of I/O (Input/output) activity and CPU instructions. Applications that need a resource-limited systems, quick response periods that employ small devices or records that are needed to be without disk like flash drives or routers for permanent or stable storage, this in-memory database is useful and advantageous in such applications.
Some important Benefits of in-memory database –
- Various Drivers & APIs – ODBC Driver, JDBC Driver, ADO.NET Provider, C++ API, ODBC API, SQL API, Objective C API, d_API.
- Ease of Use – An extra keyword to the definition of data tells the records to exist in-memory.
- Reliability – Make sure the compliance of ACID in without disk mode.
- Flexibility – Accumulate some part or entire in-memory database and on-disk database.
- Performance – An in-memory database is quicker to access and retrieve data.
Database is called as program of data collection that may be utilized for a single period or many times. It is quite essential and famous in leading enterprises, industries or organizations as the database is effective in organising and managing important data. Utilise the content type for categorising it is one of the most general ways. Database models and database architectures are other methods of classifying databases. Users can also categorise these databases depending on the hierarchical model and a network model besides these ways. Get more information about an in-memory database by determining its uses and functions in organisation data management.
This is extremely essential tool that may be employed for successful, proficient and effective enterprise data management. Today, almost all organizations and enterprises have DBMS (Data Base Management System) to manage or organise the use and maintain the storage structures of database. It is also essential to determine the different components of a DBMS. The object DBMS components include the storage engine, transaction engine, language drivers and the query engine. There are five components of the Relational DBMS: Storage engine, relational engine, transaction engine, the SQL engine and the interface drivers.
The Tasks of Database Management Systems
Application development, database maintenance, database interrogation and database development are the major four tasks of the Database Management System. An initial task, database development, is important to define and organise the storage of data structure in a specific database. Database interrogation concentrates on information retrieval, report generation and data access. Database maintenance manages or handles data safety and Application development emphasizes the involvement of forums, labels, reports, tables, data entry screens and prototypes of queries.
Other Important Details and Additional Information about Data Management Systems
Database Management System can be categorized into twelve types; some of these types are data warehouse, analytical database and operational database. The navigational database, databases of hypermedia on the web, end-user database and distributed database are other types. Relational database, real time database, document oriented database, in-memory database and navigational database can be used by users except other types. An in-memory database is the most essential type that can be mostly used.
Besides several types, also different models like the model of object database and model of post-relational database are employed for database programming. As these databases have the features of protection or security various organisations and companies have no need to be anxious about using databases. These security features are generally employed or executed with access control, auditing and encryption.
