Database Management System (DBMS) Collection
of interrelated data Set of programs to access the data DBMS contains information about a particular enterprise DBMS provides an environment that is both convenient and efficient to use. Database Applications: Banking: all transactions Airlines: reservations, schedules Universities: registration, grades Sales: customers, products, purchases Manufacturing: production, inventory, orders, supply chain Human resources: employee records, salaries, tax deductions Databases touch all aspects of our lives Database System Concepts 1.5 ©Silberschatz, Korth and Sudarshan
6.
Purpose of Database
System In the early days, database applications were built on top of file systems Drawbacks of using file systems to store data: Data redundancy and inconsistency Multiple file formats, duplication of information in different files Difficulty in accessing data Need to write a new program to carry out each new task Data isolation — multiple files and formats Integrity problems Integrity constraints (e.g. account balance > 0) become part of program code Hard to add new constraints or change existing ones Database System Concepts 1.6 ©Silberschatz, Korth and Sudarshan
7.
Purpose of Database
Systems (Cont.) Drawbacks of using file systems (cont.) Atomicity of updates Failures may leave database in an inconsistent state with partial updates carried out E.g. transfer of funds from one account to another should either complete or not happen at all Concurrent access by multiple users Concurrent accessed needed for performance Uncontrolled concurrent accesses can lead to inconsistencies – E.g. two people reading a balance and updating it at the same time Security problems Database systems offer solutions to all the above problems Database System Concepts 1.7 ©Silberschatz, Korth and Sudarshan
8.
Levels of Abstraction Physical
level describes how a record (e.g., customer) is stored. Logical level: describes data stored in database, and the relationships among the data. type customer = record name : string; street : string; city : integer; end; View level: application programs hide details of data types. Views can also hide information (e.g., salary) for security purposes. Database System Concepts 1.8 ©Silberschatz, Korth and Sudarshan
9.
View of Data An
architecture for a database system Database System Concepts 1.9 ©Silberschatz, Korth and Sudarshan
10.
Instances and Schemas Similar
to types and variables in programming languages Schema – the logical structure of the database e.g., the database consists of information about a set of customers and accounts and the relationship between them) Analogous to type information of a variable in a program Physical schema: database design at the physical level Logical schema: database design at the logical level Instance – the actual content of the database at a particular point in time Analogous to the value of a variable Physical Data Independence – the ability to modify the physical schema without changing the logical schema Applications depend on the logical schema In general, the interfaces between the various levels and components should be well defined so that changes in some parts do not seriously influence others. Database System Concepts 1.10 ©Silberschatz, Korth and Sudarshan
11.
Data Models A collection
of tools for describing data data relationships data semantics data constraints Entity-Relationship model Relational model Other models: object-oriented model semi-structured data models Older models: network model and hierarchical model Database System Concepts 1.11 ©Silberschatz, Korth and Sudarshan
12.
Entity-Relationship Model Example of
schema in the entity-relationship model Database System Concepts 1.12 ©Silberschatz, Korth and Sudarshan
13.
Entity Relationship Model
(Cont.) E-R model of real world Entities (objects) E.g. customers, accounts, bank branch Relationships between entities E.g. Account A-101 is held by customer Johnson Relationship set depositor associates customers with accounts Widely used for database design Database design in E-R model usually converted to design in the relational model (coming up next) which is used for storage and processing Database System Concepts 1.13 ©Silberschatz, Korth and Sudarshan
14.
Relational Model Attributes Example of
tabular data in the relational model Customer-id customername 192-83-7465 Johnson 019-28-3746 Smith 192-83-7465 Johnson 321-12-3123 Jones 019-28-3746 Smith Database System Concepts customerstreet customercity accountnumber Alma Palo Alto A-101 North Rye A-215 Alma Palo Alto A-201 Main Harrison A-217 North Rye A-201 1.14 ©Silberschatz, Korth and Sudarshan
15.
A Sample Relational
Database Database System Concepts 1.15 ©Silberschatz, Korth and Sudarshan
16.
Data Definition Language
(DDL) Specification notation for defining the database schema E.g. create table account ( account-number char(10), balance integer) DDL compiler generates a set of tables stored in a data dictionary Data dictionary contains metadata (i.e., data about data) database schema Data storage and definition language language in which the storage structure and access methods used by the database system are specified Usually an extension of the data definition language Database System Concepts 1.16 ©Silberschatz, Korth and Sudarshan
17.
Data Manipulation Language
(DML) Language for accessing and manipulating the data organized by the appropriate data model DML also known as query language Two classes of languages Procedural – user specifies what data is required and how to get those data Nonprocedural – user specifies what data is required without specifying how to get those data SQL is the most widely used query language Database System Concepts 1.17 ©Silberschatz, Korth and Sudarshan
18.
SQL SQL: widely used
non-procedural language E.g. find the name of the customer with customer-id 192-83-7465 select customer.customer-name from customer where customer.customer-id = ‘192-83-7465’ E.g. find the balances of all accounts held by the customer with customer-id 192-83-7465 select account.balance from depositor, account where depositor.customer-id = ‘192-83-7465’ and depositor.account-number = account.accountnumber Application programs generally access databases through one of Language extensions to allow embedded SQL Application program interface (e.g. ODBC/JDBC) which allow SQL queries to be sent to a database Database System Concepts 1.18 ©Silberschatz, Korth and Sudarshan
19.
Database Users Users are
differentiated by the way they expect to interact with the system Application programmers – interact with system through DML calls Sophisticated users – form requests in a database query language Specialized users – write specialized database applications that do not fit into the traditional data processing framework Naï ve users – invoke one of the permanent application programs that have been written previously E.g. people accessing database over the web, bank tellers, clerical staff Database System Concepts 1.19 ©Silberschatz, Korth and Sudarshan
20.
Database Administrator Coordinates all
the activities of the database system; the database administrator has a good understanding of the enterprise’s information resources and needs. Database administrator's duties include: Schema definition Storage structure and access method definition Schema and physical organization modification Granting user authority to access the database Specifying integrity constraints Acting as liaison with users Monitoring performance and responding to changes in requirements Database System Concepts 1.20 ©Silberschatz, Korth and Sudarshan
21.
Transaction Management A transaction
is a collection of operations that performs a single logical function in a database application Transaction-management component ensures that the database remains in a consistent (correct) state despite system failures (e.g., power failures and operating system crashes) and transaction failures. Concurrency-control manager controls the interaction among the concurrent transactions, to ensure the consistency of the database. Database System Concepts 1.21 ©Silberschatz, Korth and Sudarshan
22.
Storage Management Storage manager
is a program module that provides the interface between the low-level data stored in the database and the application programs and queries submitted to the system. The storage manager is responsible to the following tasks: interaction with the file manager efficient storing, retrieving and updating of data Database System Concepts 1.22 ©Silberschatz, Korth and Sudarshan
23.
Overall System Structure Database
System Concepts 1.23 ©Silberschatz, Korth and Sudarshan
24.
Application Architectures Two-tier architecture
: E.g. client programs using ODBC/JDBC to communicate with a database Three-tier architecture : E.g. web-based applications, and applications built using “middleware” Database System Concepts 1.24 ©Silberschatz, Korth and Sudarshan
