The database managements system will help from ay data loss. It have the features which that can support the updates like batch processing, locking, two-phase locking and the time stamping. The DBMS function is it has recovery services. It means that if the database is damaged, the database management system will recover the records and all the information. The data and the records need to recover and backup so that it will not be permanently lost.

Since there are so many database management systems are available, so it is important to ensure that they communicate with each other. This is because, most database software comes with an Open Database Connectivity (ODBC) driver which allows the database to incorporate with other databases. A DBMS perform several important functions that guarantee the integrity and consistency of the data in the database. Most of these functions are transparent to end users, and most can be achieved only through the use of a DBMS. They including the data dictionary management, data store management, security management and also backup and recovery management.

Answer Structured data is defined as a data that are record and being filed in the database to make it can be used efficiently. frequent the case with the selection of the type of detailed data structures should be used to allow efficient algorithms can be used. Good design data structure allows a variety of critical operations carried out by using the time and little memory space, as possible. structured data will be represent in discrete form which is in column and row form. this can make the data in the database more organized.
There are times computers may break down, a fire or other natural disaster may occur, or a user may enter inaccurate information invalidating or making records conflicting If the database is cracked or spoiled in any way, the DBMS must be able to recover the correct state of the database, and this process is called Recovery. The easiest way to do this is to make standard backups of information. This can be done at a set controlled time so in the event a catastrophe occurs, the database can be restored to the state that it was last at prior to backup. Security Security is the avoidance of illegal users accessing the database. DBMS uses features such as encryption, authentication, authorization and views to provide security to the database.
This can be done by maintaining the data independence because the system will be serasi with the users. Next is the DBMS as a storage which is it’s enforce data security and users privacy while using database. This is important for the multiusers database system whereby each of them might have different types of database. By having this DBMS functions, its will provide users with their individual database. Where they can access through their own items, data operation, and data that they used.

b) DBMS (Crucial Concept): The DBMS would be responsible for all database activities (storage, retrieval, indexing, etc) and also be responsible for keeping a detailed description of the data being held. DBMS is a program that helps users to communicate with the Operating System through an interface in order to access the data from a Database in a friendly way and as soon as possible. It allows users to store retrieve and update information quick and productive. DBMS handle to recover the database in case of system error and needs to have an organized system for security issues. c) Metadata – Data that Describes Data Metadata it’s all about data being held in a Database.
