Database access language.The DBMS must also provide an API to access the data, typically in the form of a database access language that can be used to modify data but also create database objects and secure and authorize access to the data. SQL is an example of a database access languag...
1.in addition to the isolation between the controlling and bearing on the softswitch, the IMS also implements isolation between the call control layer and service control layer; 2.the IMS, which is originated from the mobile communication network, fully supports the mobility.

The leader in the hierarchical model category is the IBM Information Management System (IMS). Object Oriented This model, which combines the relational andopens in new tabobject-oriented programming(OOP) models, is the most popular post-relational database model. ...
IMS has two major components: IMS Database Manager (IMS DB) and IMS Transaction Manager (IMS TM). IMS DB data is organized into a hierarchy, where data in each level is dependent on the data in the next, higher level. The data is arranged so that its integrity is ensured and the sto...
DBMS can be classified depending on the data structure and the way of organizing them. The four main kinds are: Hierarchical DBMS Data is represented as an unordered tree. Example: IBM IMS Network DBMS Graph structure; it allows many-to-many relationships. ...
Its limitation is that hierarchical databases cannot be used for applications where data relationships are more complex than a strict parent-child relationship. Examples include: IBM's Information Management System (IMS) Windows Registry Common use cases include banking transactions, inventory management an...
