Solutions to Practice Exercises

Atomicity of updates Failures may leave database in an inconsistent state with partial updates carried out Example: 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 Example: Two people reading a balance and updating it at the same time Security problems Hard to provide user access to some, but not all, data Database systems offer solutions to all the above problems.

Views can. Example: 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 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.

Entity-Relationship data model mainly for database design Object-based data models Object-oriented and Object-relational Semistructured data model XML Other older models:. DML also known as query language Procedural user specifies what data is required and how to get those data Declarative nonprocedural user specifies what data is required without specifying how to get those data.

Example: Find the name of the customer with customer-id select customer. Database Design The process of designing the general structure of the database: Logical Design Deciding on the database schema. Database design. Business decision What attributes should we record in the database? Computer Science decision What relation schemas should we have and how should the attributes be distributed among the various relation schemas?

The Entity-Relationship Model Models an enterprise as a collection of entities and relationships. The storage manager is responsible to the following tasks:. Efficient storing, retrieving and updating of data Storage access File organization. Depends critically on statistical information about relations which the database must maintain Need to estimate statistics for intermediate results to compute cost of complex expressions.

Concurrency-control manager controls the interaction among the. Punched cards for input Hard disks allow direct access to data Network and hierarchical data models in widespread use Ted Codd defines the relational data model. Research relational prototypes evolve into commercial systems SQL becomes industry standard Parallel and distributed database systems Object-oriented database systems s:. Large decision support and data-mining applications Large multi-terabyte data warehouses Emergence of Web commerce s:.

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. Storage structure and access method definition Schema and physical organization modification Granting users authority to access the database Backing up data Monitoring performance and responding to changes.

Database Architecture The architecture of a database systems is greatly influenced by the underlying computer system on which the database is running: Centralized Client-server Parallel multiple processors and disks Distributed. Object-Relational Data Models Extend the relational data model by including object orientation and.

Allow attributes of tuples to have complex types, including non-atomic. Preserve relational foundations, in particular the declarative access to. Provide upward compatibility with existing relational languages.
