Database Systems Introduction (INTD-3535)

  1. 1. Database Systems A Brief Introduction
  2. 2. Outline 1. Introduction 2. Description 3. Conclusion 4. References
  3. 3. Introduction <ul><li>Brief Explanation </li></ul><ul><ul><li>My investigation topic is “Database Systems”. Since my academic concentration is Computer Engineer, the Database Systems are widely used in the field. This investigation work pretends to briefly explain what is a Database System to those people who are completely know less of the topic. From now on, I will use “DB” for Database Systems. </li></ul></ul><ul><ul><li>People daily make use of DB’s without knowing it. For example, when checking emails, you are using a DB System. </li></ul></ul>
  4. 4. Introduction <ul><li>Brief Explanation (cont) </li></ul><ul><ul><li>Another example is: when you make use of the cell phone, you are dialing a number stored in the phone’s memory. That’s a DB. </li></ul></ul><ul><ul><li>Another example, but more complex, is the academic system of our college. All the record of courses, students and professors, is stored in a DB system. </li></ul></ul>
  5. 5. Introduction <ul><li>Terms Definition </li></ul><ul><ul><li>Database </li></ul></ul><ul><ul><ul><li>A database is a structured collection of records or data that is stored in a computer system. The structure is achieved by organizing the data according to a database model. </li></ul></ul></ul><ul><ul><li>Database Model </li></ul></ul><ul><ul><ul><li>A database model is the structure or format of the database. </li></ul></ul></ul><ul><ul><li>Relational Database </li></ul></ul><ul><ul><ul><li>It’s a database model based on the first order predicate logic, created in 1969. </li></ul></ul></ul>
  6. 6. Description <ul><li>Database Systems Applications </li></ul><ul><ul><li>DB Management Systems (DBMS) </li></ul></ul><ul><ul><ul><li>A DBMS is a set of software programs that controls the organization, storage, management, and retrieval of data in a database. DBMS are categorized according to their data structures or types. It is a set of prewritten programs that are used to store, update and retrieve a Database. </li></ul></ul></ul><ul><ul><li>Database Driven Web Sites </li></ul></ul><ul><ul><ul><li>Commonly known as dynamic web sites. Those websites grab the information from a DB. In a same manner, they put information on a DB. For example, your bak’s page is a DB driven site. </li></ul></ul></ul>
  7. 7. Description <ul><li>Database Systems Applications </li></ul><ul><ul><li>Mobile Databases </li></ul></ul><ul><ul><ul><li>Mobile databases are databases that allows the development and deployment of database applications for handheld devices, thus, enabling relational database based applications in the hands of mobile workers. </li></ul></ul></ul><ul><ul><ul><li>Some of the commercially available Mobile relational Database systems are: </li></ul></ul></ul><ul><ul><ul><ul><li>IBM's DB2 Everywhere 1.0 </li></ul></ul></ul></ul><ul><ul><ul><ul><li>Oracle Lite </li></ul></ul></ul></ul><ul><ul><ul><ul><li>Sybase's SQL </li></ul></ul></ul></ul>
  8. 8. Description <ul><li>Research Methods and Description </li></ul><ul><ul><li>To gather all information regarding Database Systems I followed some steps that are common to the normal users. </li></ul></ul><ul><ul><li>I started making a search in Google by the term: database system. </li></ul></ul><ul><ul><li>Then, using the General Library web page, I’d continued the information gathering. </li></ul></ul>
  9. 9. Conclusion <ul><li>Suggestions </li></ul><ul><ul><li>Regarding my topic of investigation, the only thing I will suggest is that the Companies responsibles of creating and managing Database Systems may bring some more information to the common user that doesn’t have direct knowledge of DB Systems. </li></ul></ul><ul><ul><li>For example, we can bring information to people letting them know that DB Systems are everywhere. </li></ul></ul>
  10. 10. Conclusion <ul><li>Easiness of Gathering </li></ul><ul><ul><li>Gathering information was a relatively easy process. For luck, information of DB’s is widely available. </li></ul></ul><ul><ul><li>Even when the information is widely available, some sources were difficult to find. For example, to find thesis or magazines articles was more difficult than to find internet information. </li></ul></ul>
