Please respond to the following: Looking back, we can see three distinct waves of database technologies. Methods for collecting, organizing, and processing data existed before the electronic computer, of course. Libraries—especially those using comprehensive indexing systems—represent a form of data store. And even before the electronic computer, information was still being processed mechanically: Punch card technology was in widespread use at the end of the 19th century and the tabulating machines of that era gave rise to the IBM of modern times. Research the evolution of databases.

Discuss the historical development of database management systems and logical data models, starting from the file-based system of the past to today. Make sure you explain why databases were developed. Engage the following resource(s) to get started.

PLEASE RESPOND TO CLASSMATE DISCUSSION WHETHER YOU AGREE OR NOT & A DETAILED WHY: From my reading, I understand that the early stages of database use started with the use of punch cards for input, output, and data storage. Herman Hollerith was the inventor of the punch card database method, which acted as the memory for the tabulating machine. The tabulating machine was an electromechanical machine designed to assist in summarizing information stored on punched cards. One of the first uses of this machine was for the 1890 Census.

Following the punch card database method was the use of coding which began in the mid 1900’s. The coding method utilized large computers to complete the database processing and later developed into a more complex method known as the Integrated Database System and was considered the first “DBMS”. This technology was developed by Charles W. Bachman in 1960. By the mid 1960’s, the database technology developed into what was known as the Common Business Oriented Language (COBOL), or, the CODASYL approach. Due to the complexity and lack of desired features of the CODASYL, the Relational Database was created. The popular database name we know as SQL was developed in 1974 and became further advanced the following years. By the 1980’s, SQL became the standard for database technologies. Examples of database types we see today are MySQL, Oracle, and DB2.
