SQLite VS IBM DB2
DB2
IBM developed the Database named DB2. It is a database that follows relational database management system principles. By using DB2, we can fetch the data, analyse it and store it efficiently. DB2 is based on Object-Oriented features and non-relational XML structures. It is a group of related data management products that include data servers developed and marketed by IBM. It is developed on a concept based on SQL, i.e., standard query language on the relational database system, which means DB2 uses SQL queries to retrieve and store the data into the Database. We can use DB2 on AS/400 IBM mainframe and personal computers.
DB2 also supports the storage of non-relational formats like XML and JSON DP. It is not open-source but provides some free distributions, and IBM fully owns it, and if we want to run on large servers, we should have to pay for the licensing.
Let's see some advantages:
DB2 has been around for years and has matured as a robust RDBMS.
1. Powerful Structures Query Language
2. Various Platform support.
3. IBM Support
4. Fetching of data is significantly fast
5. It provides high security
6. It is independent
7. It provides very high concurrency, Allowing multiple applications and users to access the data parallelly and Concurrently.
8. Redundancy is low
9. It provides flexibility with the designs
10 It offers easy access, and user is not required to know the physical relationships of the Database they wish to access
11. It is reliable, secure and offers high availability
12. It can efficiently handle large volumes of data
13. It can work with various operating systems
Let's see some disadvantages
1. It is not open source, so we need licensing, which is quite expensive, and support is paid.
2. We can create the tables, but it should be within block sizeof tablespace.
3. It consumes mainframe processors
4. It is difficult to resolve the issues and debug the issue.
5. The BIND process is time costly for the larger plans.
What is SQLite?
It is a library used to implement an SQL database engine that is self-sufficient, zero-configuration, transactional, zero-configuration, and serverless. It is a database that does not need any configuration for your system. It is not a standalone process, same as other databases; we can link it as we need either statically or dynamically with our application. It fetches its storage files directly.
Disadvantages of SQLite:
SQLite does not provide integrity to data when various users try to update the Database simultaneously.
