Legal and ethical Standards
Availability – the system should allow data to be available to the authorized person at the right time and with less effort needed to access it.
Integrity – data in the database should modified by only the authorized persons and in the correct way. Such that such modification or alterations do not bring conflict in the database meaning data should not be tampered with. If tampered this could amount to misuse.
Confidentiality factor- a system should be designed in such a way that it does not allow unauthorized person to access information which they don’t have permission for Vinyl records . There should be restriction to data accessed by different parties.
The system being developed should not negatively affect the health, safety and welfare of the users instead it should make life better.
A system developed should not perform illegal actions such as corrupting data, leaking of information or used in spying.
The policies and procedures used in the operation to the system being developed should must assure reliable data.
A system developed should be licensed; the legal process of obtaining license should be used.
One should not use software product that they don’t have license or are not authorized to use by the owner. Intellectual rights should not be violated.
Legal compliance
To ensure accurate data is entered every time the system should be able to validate data before Restricting access to data in the database through separating data into different tables with where user privileges are restricted. The design of the database should enable separating different object attributes of entities to restrict access to the whole entity information hence able to protect data from unauthorized access.
Database design methodology used in this case must allow scalability of the information such that the database will continue to function properly even when the data is increasing and hence ensure availability and reliability.
Integrity of the data should be done by setting access privileges in the physical design of the database which is implemented.
Security should be incorporated in all phases of the database development cycle. In the design phase the system.
Standards
The access to different types of databases is done through DBMS only, so for this the standards are easier to enforce. Standards may include and relate to structure of data, format of data, naming of data etc.... generally standardized data is used for the purpose of data exchange between various systems.

MobileDBSecurity.pptx
Dr. Wei Chen discusses database security. The three components of database security are confidentiality, integrity, and availability (CIA). Confidentiality involves protecting data from unauthorized disclosure through encryption and access controls. Integrity ensures data is not tampered with using hashing and signing. Availability ensures authorized users can access data when needed through backups and DDoS protection. Mobile database security poses additional challenges due to devices leaving secure networks. Encrypting sensitive data and using device authentication can help. Content providers allow sharing data between apps if necessary but increase security risks. Auditing, access controls, and input validation are important defenses against threats like SQL injection.
Database
Data exists in unorganized files but can be organized into a database using a database management system (DBMS). Traditional file management involves storing data in files that can be manually accessed and updated, but this leads to problems like data redundancy, lack of flexibility, and security issues. A DBMS centralizes data, allows efficient management and sharing of data, and provides access to stored data through application programs to reduce these problems.
01 database security ent-db
Databases store logically interrelated data representing real-world aspects. They require security measures to protect data confidentiality, integrity, and availability from threats. Common threats include privilege abuse, injection attacks, and unmanaged sensitive data. Database security uses prevention techniques like access control and detection techniques like auditing. Access control policies include discretionary access control based on authorization rules, mandatory access control, and role-based access control. Views and stored procedures also help implement access control by restricting data access.

Santosh Kumar Meher(2105040008) DISTRIBUTED DATABASE.pptx
Distributed database consists of multiple databases that are connected with each other and are spread across different physical locations. The data that is stored on various physical locations can thus be managed independently of other physical locations. The communication between databases at different physical locations is thus done by a computer network.
A distributed database is a database that is not limited to one computer system.
It is like a database that consists of two or more files located in different computers or sites either on the same network or on an entirely different network.
Instead of storing all of the data in one database, data is divided and stored at different locations or sites which do not share any physical component.
The data can be easily accessed, managed, modified, updated, controlled, and organized in a database.
Database user and administrator.pptx
1) The document discusses different types of database users and the role of the database administrator. There are four types of database users: naive users, application programmers, sophisticated users, and specialized users.
2) The database administrator is responsible for defining the database schema, storage structure, granting access authorizations, and performing routine maintenance like backups and monitoring performance.
3) The roles and responsibilities of each user type and the database administrator are outlined. Naive users interact through simple programs, application programmers create interfaces, sophisticated users use query languages, and specialized users build custom applications.

For each topology, it describes the logical layout, advantages, disadvantages, and examples of applications. The key points are that topology refers to the layout of connected devices on a network, different topologies use different connection schemes (fully connected, centralized hub, shared backbone cable, circular connection, hierarchical tree, etc.), and choosing a topology depends on factors like cost, cable needs, growth requirements, and cable types supported.
csmacd.pptx
CSMA/CD is a media access control method used in Ethernet that improves on CSMA by allowing stations to detect collisions. When a collision is detected, the station sends a jam signal and waits a random time before resending the frame. This allows collisions to be handled efficiently. CSMA/CD provides reliable transmission since collisions are detected and packets are retransmitted, making it effective for local area networks, though it has limitations such as maximum segment length and scaling to large networks.

unit 1 section 7.pptx
Multiplexing allows multiple communication signals to be transmitted across a shared channel by separating the signals to prevent interference and ensuring each destination receives only the data from the corresponding source. It uses either time division multiplexing (TDM), where signals take turns transmitting over the channel and are marked with an identifier, or frequency division multiplexing (FDM), where signals can transmit simultaneously by using different frequency channels. Multiplexing is commonly used with transmission systems and network hardware to efficiently share bandwidth and reduce transmission costs.
ARP.pptx
ARP stands for Address Resolution Protocol and is used to map IP addresses to MAC addresses on a local network. There are different types of ARP including Proxy ARP, Gratuitous ARP, Reverse ARP, and Inverse ARP. Proxy ARP allows a router to respond to ARP requests and map the router's MAC address to the target IP address. Gratuitous ARP helps identify duplicate IP addresses on a network. Reverse ARP allows a client to request its IPv4 address from a router table.
interface.pptx
A DBMS is software that manages and stores data in an organized way.
